NAME

       neomuttrc - Configuration file for the NeoMutt Mail User Agent (MUA)

DESCRIPTION

       A NeoMutt configuration file consists of a series of “commands”. Each line of the file may
       contain one or more commands. When multiple commands are used, they must be separated by a
       semicolon (“;”).

       The  hash  mark,  or pound sign (“#”), is used as a “comment” character. You can use it to
       annotate your initialization file. All text after the comment character to the end of  the
       line is ignored.

       Single  quotes  (“'”)  and  double quotes (“"”) can be used to quote strings which contain
       spaces or other special characters. The difference between the  two  types  of  quotes  is
       similar  to  that  of  many  popular shell programs, namely that a single quote is used to
       specify a literal string (one that is not interpreted for shell variables or quoting  with
       a  backslash  [see next paragraph]), while double quotes indicate a string which should be
       evaluated. For example, backticks are evaluated inside of double quotes,  but  not  single
       quotes.

       “\” quotes the next character, just as in shells such as Bash and Zsh. For example, if you
       want to put quotes (“"”) inside of a string, you can use “\” to force the  next  character
       to be a literal instead of interpreted character.

       “\\”  means  to  insert  a  literal  “\”  into  the line. “\n” and “\r” have their usual C
       meanings of line feed (LF) and carriage return (CR), respectively.

       A “\” at the end of a line can be used to split commands  over  multiple  lines,  provided
       that the split points don't appear in the middle of command names.

       It  is also possible to substitute the output of a Unix command in an initialization file.
       This is accomplished by enclosing the command in backticks (`command`).

       Unix environment variables can be accessed like the way it is done in shells like  sh  and
       Bash: Prepend the name of the variable by a dollar (“$”) sign.

COMMANDS

   Configuration Commands
       The following are the commands understood by NeoMutt:

       account-hook regex command

              This  hook  is  executed  whenever  you  access  a remote mailbox. Useful to adjust
              configuration settings to different IMAP or POP servers.

       alias [ -group name ... ] key address [, address ... ]
       unalias [ -group name ... ] { * | key ... }

              alias defines a surrogate key for the  given  address(es).  Each  address  will  be
              resolved  into  either an email address (user@example.com) or a named email address
              (User Name <user@example.com>).  The address may be specified in either format,  or
              in the format “user@example.com (User Name)”.

              Note:  If  you want to create an alias for more than one address, you must separate
              the addresses with a comma (“,”).

              unalias removes the alias corresponding to the given key or all aliases when “*” is
              used as an argument.

              The  optional -group flag causes the address(es) to be added to or removed from the
              named group.

       alternates [ -group name ... ] regex [ regex ... ]
       unalternates [ -group name ... ] { * | regex ... }

              alternates is used to inform NeoMutt about alternate addresses  where  you  receive
              mail;  you can use regular expressions (regex) to specify alternate addresses. This
              affects NeoMutt's idea about messages from you, and messages addressed to you.

              unalternates can be used to write exceptions to alternates regular  expression.  To
              remove  a regular expression from the alternates list, use the unalternates command
              with exactly the same regex or use “*” to remove all entries.

              The optional -group flag causes all of the subsequent  regular  expressions  to  be
              added to or removed from the named group.

       alternative_order mime-type[/mime-subtype] [ mime-type[/mime-subtype] ... ]
       unalternative_order { * | mime-type[/mime-subtype] ... }

              alternative_order command permits you to define an order of preference that is used
              by NeoMutt to determine which part of a multipart/alternative body  to  display.  A
              mime-subtype  of  “*”  matches  any multipart/alternative subtype, as does an empty
              mime-subtype.

              unalternative_order removes entries from the ordered list  or  deletes  the  entire
              list when “*” is used as an argument.

       attachments { + | - }disposition mime-type [ mime-type ... ]
       unattachments { + | - }disposition mime-type [ mime-type ... ]
       attachments ?
       unattachments *

              You  can  make  your  message index display the number of qualifying attachments in
              each message, or search for messages by attachment count. You  also  can  configure
              what  kinds  of  attachments  qualify  for  this  feature  with the attachments and
              unattachments commands.

              disposition is  the  attachment's  Content-Disposition  type  —  either  inline  or
              attachment. You can abbreviate this to I or A.

              Disposition  is  prefixed  by  either a + symbol or a - symbol. If it's a +, you're
              saying that you want to allow this disposition and MIME type to qualify. If it's  a
              -,  you're saying that this disposition and MIME type is an exception to previous +
              rules.

              mime-type is the MIME type of the attachment you want the command to affect. A MIME
              type  is  always  of  the  format  major/minor. The major part of mime-type must be
              literal text (or the special token “*”,  but  the  minor  part  may  be  a  regular
              expression. Therefore, “*/.*”  matches any MIME type.

              Note  that the first MIME part is treated slightly differently: It is almost always
              the message text.  Thus, it is not counted as an attachment if its  disposition  is
              inline and it is not a multipart/* or message/* MIME-type.

              Entering  the  command “attachments ?” as a command will list your current settings
              in neomuttrc format, so that it can be pasted elsewhere.

              Entering the command “unattachments *” as  a  command  will  Clear  all  attachment
              settings.

       auto_view mime-type[/mime-subtype] [ mime-type[/mime-subtype] ... ]
       unauto_view { * | mime-type[/mime-subtype] ... }

              This  commands permits you to specify that NeoMutt should automatically convert the
              given mime-types to text/plain when displaying messages. For this  to  work,  there
              must  be  a  mailcap(5) entry for the given mime-type with the copiousoutput option
              set.  A mime-subtype of “*” matches any multipart/alternative subtype, as  does  an
              empty mime-subtype.

       bind map[,map ... ] key function
       unbind { * | map | [,map...]} [ key ]

              This  command  allows  you  to change the default or define additional key bindings
              (operation invoked when pressing a key).

              map specifies in which menu the binding belongs. Multiple maps may be specified  by
              separating  them  with  commas (no additional whitespace is allowed). The currently
              defined maps are: alias, attach, browser, compose,  editor,  generic,  index,  mix,
              pager, pgp, postpone, query and smime.

              key  is  the  key (or key sequence) you wish to bind, e.g.  “\Ca” for control-A. In
              addition, key may be specified as a three digit octal number prefixed with a “\” or
              as  a  symbolic  name.  The  <what-key> function can be used to explore keycode and
              symbolic names for the keys on your keyboard.

              function specifies which action to take when key is pressed. Note that the function
              name is to be specified without angle brackets.

              Missing  key sequence in unbind command means unbind all bindings in menus given in
              map .

              For more information on keys and functions, please consult the NeoMutt manual.

       charset-hook alias charset
       iconv-hook charset local-charset

              charset-hook defines an alias for a character  set.  This  is  useful  to  properly
              display messages which are tagged with a character set name not known to NeoMutt.

              iconv-hook  defines a system-specific name for a character set. This is useful when
              your system's iconv(3) implementation does not understand MIME character set  names
              (such as iso-8859-1), but instead insists on being fed with implementation-specific
              character set names (such as 8859-1). In this  specific  case,  you'd  put  “iconv-
              hook iso-8859-1 8859-1” into your configuration file.

       color object [ attribute ... ] foreground background
       color { header | body } [ attribute ... ] foreground background regex
       color status foreground background [regex [ num ]]
       color index-object [ attribute ... ] foreground background pattern
       color compose composeobject foreground background
       color compose composeobject [ attribute ... ] foreground background
       uncolor { index-object | header | body } { * | pattern ... }

              If  your  terminal supports color, these commands can be used to assign foreground/
              background combinations to certain objects.  The  currently  defined  objects  are:
              attach_headers,  attachment,  body,  bold, error, hdrdefault, header, index, index_
              author, index_collapsed, index_date, index_flags, index_label, index_number, index_
              size,  index_subject,  index_tag,  index_tags, indicator, markers, message, normal,
              progress,  prompt,  quoted,  quotedN,  search,  signature,   status,   stripe_even,
              stripe_odd, tilde, tree, underline.

              If the sidebar is enabled the following objects are also valid: sidebar_background,
              sidebar_divider, sidebar_flagged,  sidebar_highlight,  sidebar_indicator,  sidebar_
              new, sidebar_ordinary, sidebar_spool_file.

              The  body  and  header  objects allow you to restrict the colorization to a regular
              expression. The index-object permits you to select colored messages by pattern.

              The header and body match regex in the header/body of a message,  index-object  can
              match  pattern  in the message index.  Note that IMAP server-side searches (=b, =B,
              =h) are not supported for color index patterns.

              The status object optionally takes an regex and a match number.  If  the  regex  is
              given,  only  the  matching parts are colored.  If additionally the match number is
              given, only that sub-match of the regex is colored.

              Valid   composeobjects    include    header,    security_encrypt,    security_sign,
              security_both, security_none.

              Valid  colors  include:  default,  black,  red, green, yellow, blue, magenta, cyan,
              white, #RRGGBB, colorN.

              Valid attributes include: none, bold, underline, reverse, and standout.

              The uncolor command can be applied to the index, header and body objects  only.  It
              removes  entries  from the list. You must specify the same pattern specified in the
              color command for it to be removed. The pattern “*” is a special token which  means
              to clear the color list of all entries.

              For further information on colorization, please consult the NeoMutt manual.

       crypt-hook regex keyid

              The  crypt-hook  command  provides  a method by which you can specify the ID of the
              public key to be used when encrypting messages to a certain recipient. The  meaning
              of keyid is to be taken broadly: This can be a different email address, a numerical
              keyid, or even just an arbitrary search string. You may  use  multiple  crypt-hooks
              with  the  same  regex; multiple matching crypt-hooks result in the use of multiple
              keyids for a recipient.

       index-format-hook name [!]pattern format-string
              This command is used to inject format strings dynamically into $index_format  based
              on pattern matching against the current message.

              The $index_format expando %@name@ specifies a placeholder for the injection. Index-
              format-hooks with the same name are  matched  using  pattern  against  the  current
              message.  Matching is done in the order specified in the .neomuttrc, with the first
              match being used. The hook's format-string is then substituted and evaluated.

       exec function [ function ... ]

              This command can be used to execute any  function.  Functions  are  listed  in  the
              function reference. “exec function” is equivalent to “push <function>”.

       fcc-save-hook pattern mailbox
       fcc-hook pattern mailbox
       save-hook pattern mailbox

              fcc-save-hook  is  a  shortcut, equivalent to doing both a fcc-hook and a save-hook
              with its arguments, including %-expansion on mailbox according to $index_format.

              fcc-hook is used to save outgoing mail in a mailbox other  than  $record.   NeoMutt
              searches  the initial list of message recipients for the first matching pattern and
              uses mailbox as the default “Fcc:” mailbox. If no match is found the  message  will
              be saved to $record mailbox.

              save-hook  is  used  to  override  the  default  mailbox used when saving messages.
              mailbox will be used as the default if the message matches pattern.

              To provide more flexibility and good defaults,  NeoMutt  applies  the  expandos  of
              $index_format  to  mailbox  after  it  was  expanded. See PATTERNS section below or
              consult section “Message Matching in Hooks” in NeoMutt manual  for  information  on
              the exact format of pattern.

       folder-hook [-noregex] regex command

              When  NeoMutt enters a folder which matches regex (or, when regex is preceded by an
              exclamation mark, does not  match  regex),  the  given  command  is  executed.  The
              -noregex switch controls whether regex is matches as simple string equality or full
              regex match.

              When several folder-hooks match a given mail folder, they are executed in the order
              given in the configuration file.

       group [ -group name ... ] { -rx regex ... | -addr address ... }
       ungroup [ -group name ... ] { * | -rx regex ... | -addr address ... }

              group  is  used  to  directly  add  either  addresses or regular expressions to the
              specified group or groups. The different  categories  of  arguments  to  the  group
              command  can  be  in  any order. The flags -rx and -addr specify what the following
              strings (that cannot begin with a  hyphen)  should  be  interpreted  as:  either  a
              regular expression or an email address, respectively.

              ungroup is used to remove addresses or regular expressions from the specified group
              or groups. The syntax  is  similar  to  the  group  command,  however  the  special
              character “*” can be used to empty a group of all of its contents.

              These  address groups can also be created implicitly by the alias, lists, subscribe
              and alternates commands by specifying the optional -group option.

              Once defined, these address groups can be used in patterns to search for and  limit
              the display to messages matching a group.

       hdr_order header [ header ... ]
       unhdr_order { * | header ... }

              With  the  hdr_order command you can specify an order in which NeoMutt will attempt
              to present these headers to you when viewing messages.

              “unhdr_order *” will clear all previous headers from the order list, thus  removing
              the header order effects set by the system-wide startup file.

       ifdef symbol "config-command [ args ... ]"
       ifndef symbol "config-command [ args ... ]"
       finish

              The  ifdef  feature introduces three new commands to NeoMutt and allow you to share
              one config file between versions  of  NeoMutt  that  may  have  different  features
              compiled in.

              └──────────────────────────────────┴──────────────────────┘
              A  list  of  compile-time  symbols  can  be  seen  in  the  output  of  the command
              “neomutt -v” (in the “Compile options” section).

              finish is particularly useful when combined with ifndef.

       ignore string [ string ... ]
       unignore { * | string ... }

              The ignore command allows you to specify header fields  which  you  don't  normally
              want  to  see  in the pager. You do not need to specify the full header field name.
              For example, “ignore content-” will ignore all header fields that  begin  with  the
              string “content-”, “ignore *” will ignore all headers.

              To  remove  a  previously  added token from the list, use the unignore command. For
              example, “unignore *” will remove all tokens from the ignore list.

       lists [ -group name ... ] regex [ regex ... ]
       unlists [ -group name ... ] { * | regex ... }
       subscribe [ -group name ... ] regex [ regex ... ]
       unsubscribe [ -group name ... ] { * | regex ... }

              NeoMutt maintains two lists of mailing list address regular expressions, a list  of
              subscribed mailing lists, and a list of known mailing lists. All subscribed mailing
              lists are known.

              The lists command adds a mailing list address to the list of known  mailing  lists.
              The  unlists  command removes a mailing list from the lists of known and subscribed
              mailing lists.

              The subscribe command adds a mailing list to the  lists  of  known  and  subscribed
              mailing  lists.  The  unsubscribe  command  removes  it from the list of subscribed
              mailing lists.

              The -group flag adds all of the subsequent regular expressions to the named group.

       macro menu[,menu ... ] key sequence [ description ]
       unmacro { * | menu | [,menu...]} [ key ]

              This command binds the given sequence of keys to the given key in the given menu or
              menus.  For  currently  defined  menus, see bind command above. To specify multiple
              menus, put only a comma between the menus.

              Optionally you can specify a descriptive text after sequence, which is shown in the
              help screens if they contain a description.

              Missing  key sequence in unmacro command means unmacro all macros in menus given in
              menu.

       mailboxes [[-label label] | -nolabel]
                  [[-notify | -nonotify]
                  [-poll | -nopoll]
                  mailbox] [ ... ]
       named-mailboxes label mailbox [label mailbox ... ]
       unmailboxes { * | mailbox ... }

              The mailboxes specifies folders which can receive mail and which  will  be  checked
              for  new messages. When changing folders, pressing space will cycle through folders
              with new mail.

              The named-mailboxes is an alternative to mailboxes -label label.   NeoMutt  can  be
              configured to display the label instead of the mailbox path.

              The  unmailboxes  command  is  used  to remove a file name from the list of folders
              which can receive mail. If “*” is specified as the file name, the list is emptied.

       mailto_allow { * | header-field ... }
       unmailto_allow { * | header-field ... }

              As a security measure, NeoMutt will only add  user-approved  header-fields  from  a
              mailto:  URL.  This  is  necessary since NeoMutt will handle certain header-fields,
              such as Attach, in a special way.  The  mailto_allow  and  unmailto_allow  commands
              allow the user to modify the list of approved headers.

              NeoMutt  initializes  the default list to contain only the Subject and Body header-
              fields, which are the only requirement specified by the  mailto:  specification  in
              RFC2368, and the Cc, In-Reply-To, References headers to aid with replies to mailing
              lists.

       echo message
              Prints message to the message window. After printing the message, echo  will  pause
              for the number of seconds specified by $sleep_time.

       cd directory
              Changes the current working directory.

       mbox-hook [-noregex] regex mailbox

              When  NeoMutt changes to a mail folder which matches regex, mailbox will be used as
              the “mbox” folder, i.e. read messages will be moved to that folder  when  the  mail
              folder  is  left.  The  -noregex switch controls whether regex is matches as simple
              string equality or full regex match.

              Note that execution of mbox-hooks is dependent on the $move configuration variable.
              If set to “no” (the default), mbox-hooks will not be executed.

              The first matching mbox-hook applies.

       message-hook pattern command

              Before  NeoMutt  displays  (or  formats for replying or forwarding) a message which
              matches the given pattern (or, when it is preceded by an exclamation mark, does not
              match  the  pattern),  the  given command is executed.  When multiple message-hooks
              match, they are executed in the order in which  they  occur  in  the  configuration
              file.

       mime_lookup mime-type[/mime-subtype] [ mime-type[/mime-subtype] ... ]
       unmime_lookup { * | mime-type[/mime-subtype] ... }

              This  command  permits  you to define a list of “data” MIME content types for which
              NeoMutt will try to determine the actual file type from the file name, and not  use
              a  mailcap(5) entry given for the original MIME type. For instance, you may add the
              application/octet-stream MIME type to this list.

              In addition, the unmime_lookup command may be used to disable this feature for  any
              particular MIME type if it had been set, for example in a global neomuttrc.

       mono object attribute
       mono { header | body } attribute regex
       mono index-object attribute pattern
       unmono { index-object | header | body } { * | pattern ... }

              For  terminals  which  don't  support  color,  you  can  still assign attributes to
              objects.

       my_hdr string
       unmy_hdr { * | field ... }

              Using my_hdr, you can define headers which  will  be  added  to  the  messages  you
              compose. unmy_hdr will remove the given user-defined headers.

       open-hook regex "shell-command"
       close-hook regex "shell-command"
       append-hook regex "shell-command"

              These  commands  provide  a  way  to  handle  compressed  folders.  The given regex
              specifies which folders are taken as compressed (e.g.  "\.gz$"). The commands  tell
              NeoMutt  how  to uncompress a folder (open-hook), compress a folder (close-hook) or
              append a compressed mail to a compressed folder (append-hook). The shell-command is
              a  printf(3) like format string and must contain two placeholders for from (%f) and
              to (%t) filenames which should be placed inside single-quotes to prevent unintended
              shell expansions. Examples:

                     append-hook '\.gz$' "gzip --stdout '%t' >> '%f'"
                     close-hook '\.gz$' "gzip --stdout '%t' > '%f'"
                     open-hook '\.gz$' "gzip --stdout --decompress '%f' > '%t'"

       push string

              This  command  adds  the  named string to the beginning of the keyboard buffer. The
              string may contain control characters,  key  names  and  function  names  like  the
              sequence  string  in  the  macro  command.  You  may  use it to automatically run a
              sequence of commands at startup, or when entering certain folders.

              For using functions, it's important to use angle brackets (“<”  and  “>”)  to  make
              NeoMutt  recognize  the  input  as  a  function  name.  Otherwise  it will simulate
              individual just keystrokes.

       reply-hook pattern command
       send-hook pattern command
       send2-hook pattern command

              These commands can be used to execute arbitrary configuration commands  based  upon
              recipients  of  the  message.  pattern  is  used  to match the message, see section
              “Message Matching in Hooks” in  manual  for  details.   command  is  executed  when
              pattern matches.

              reply-hook  is  matched  against  the  message  you are replying to, instead of the
              message you are sending. send-hook is matched against all messages,  both  new  and
              replies.  Note,  reply-hooks  are  matched  before the send-hook, regardless of the
              order specified in the user's configuration file.

              send2-hook is matched every time a message is changed, either by editing it, or  by
              using the compose menu to change its recipients or subject.  send2-hook is executed
              after send-hook, and can, e.g., be used to set parameters  such  as  the  $sendmail
              variable  depending  on  the  message's  sender  address. Note, send-hooks are only
              executed once after getting the initial list of recipients.

       score pattern value
       unscore { * | pattern ... }

              The score command adds value to a message's score if pattern matches it. pattern is
              a string in the format described in the PATTERNS section below. value is a positive
              or negative integer.  A message's final score is the  sum  total  of  all  matching
              score entries.

              The  unscore command removes score entries from the list. You must specify the same
              pattern specified in the score command for it to be removed. The pattern “*”  is  a
              special token which means to clear the list of all score entries.

       set { [ no | inv | & | ? ]variable } [ ... ]
       set { variable=value | variable+=increment | variable-=decrement } [ ... ]
       unset variable  [ variable ... ]
       reset variable  [ variable ... ]
       toggle variable [ variable ... ]
       set variable ?

              These commands are used to set and manipulate configuration variables.

              NeoMutt  knows  four basic types of variables: boolean, number, string, string list
              and quadoption. Boolean variables can be set (true),  unset  (false),  or  toggled.
              Number  variables  can  be  assigned  a  positive  integer  value.  Value of number
              variables can be incremented "+=" and decremented "-=". String list  variables  use
              "+=" for appending increment to the string list and "-=" for removal decrement from
              the string list.

              String variables consist of any number of printable characters and must be enclosed
              in  quotes  if  they  contain spaces or tabs. You may also use the escape sequences
              “\n” and “\t” for newline and tab, respectively. Content of a string variables  can
              be extended using "+="

              Quadoption  variables are used to control whether or not to be prompted for certain
              actions, or to specify a default action. A value of yes will cause the action to be
              carried  out automatically as if you had answered “yes” to the question. Similarly,
              a value of no will cause the action to be carried out as if you had answered  “no”.
              A  value  of  ask-yes will cause a prompt with a default answer of “yes” and ask-no
              will provide a default answer of “no”.

              The toggle command  automatically  prepends  the  “inv”  prefix  to  all  specified
              variables.  The  unset  command  automatically  prepends  the  “no”  prefix  to all
              specified variables. If you use the command set and prefix the  variable  with  “&”
              this has the same behavior as the reset command.

              The reset command resets all given variables to the compile time defaults. With the
              reset command there exists the special variable all, which allows you to reset  all
              variables to their system defaults.

              Using  the  <enter-command>  function,  you  can  query  the value of a variable by
              suffixing the name of the variable with a question mark: ":set  allow_8bit?".   The
              old prefix query syntax (":set ?allow_8bit") is also still supported.

       setenv { ?variable | variable value }
       unsetenv variable

              You  can  alter the environment that NeoMutt passes on to its child processes using
              the setenv and unsetenv operators.

              You can also query current environment values by prefixing a “?” character.

       sidebar_pin mailbox [ mailbox ...]
       sidebar_unpin { * | mailbox ... }

              The sidebar_pin command specifies mailboxes that will always be  displayed  in  the
              sidebar, even if $sidebar_new_mail_only is set and the mailbox does not contain new
              mail.

              The sidebar_unpin command is used to remove a  mailbox  from  the  list  of  always
              displayed mailboxes. Use “sidebar_unpin *” to remove all mailboxes.

       source filename

              This  command allows the inclusion of initialization commands from other files.  If
              the filename begins with a tilde (“~”), it will be expanded to  the  path  of  your
              home directory.

              If  the  filename ends with a vertical bar (“|”), then filename is considered to be
              an executable program from which to read input, (e.g.  “source ~/bin/myscript|”).

              If the filename is relative and the command source is executed from the context  of
              a configuration file, then the filename is interpreted relative to the directory of
              that configuration file.  If the command is executed  outside  of  a  configuration
              file,  e.g.  from  the  prompt,  then  the  filename is interpreted relative to the
              current working directory (see cd on how to change the current working directory at
              runtime).

              Note:  A  hook  remembers  the  configuration  file  it was defined in and sets the
              context to that file when executing its commands.  As a  result  a  source  command
              inside  a  hook  is  executed in the context of the configuration file the hook was
              defined in.  Thus relative filenames are interpreted relative to the  configuration
              file the hook is defined in.

       spam regex format
       nospam { * | regex }

              NeoMutt has generalized support for external spam-scoring filters. By defining your
              spam regexs with the spam and nospam commands, you can limit, search, and sort your
              mail  based  on its spam attributes, as determined by the external filter. You also
              can display the spam attributes in your index display using the %H selector in  the
              $index_format  variable. (Tip: try "%<H?[%H] >" to display spam tags only when they
              are defined for a given message).

              For further information on spam-scoring filters, please consult the  section  “Spam
              Detection” in the NeoMutt manual.

       subjectrx regex replacement
       unsubjectrx { * | regex }

              The  subjectrx  command  specifies  a  regular  expression  which, if detected in a
              message subject, causes the subject to be replaced with the replacement value.  The
              replacement is subject to substitutions in the same way as for the spam command: %L
              for the text to the left of the match, %R for text to the right of the  match,  and
              %1  for  the  first  subgroup  in  the match (etc). If you simply want to erase the
              match, set it to “%L%R”.  Any number of subjectrx commands may coexist.

              Note this well: the replacement value replaces the entire  subject,  not  just  the
              match!

              unsubjectrx  removes  a given subjectrx from the substitution list.  If “*” is used
              as the argument, all substitutions will be removed.

       subscribe-to imap-folder-uri
       unsubscribe-from imap-folder-uri

              Tell the IMAP server to subscribe to or unsubscribe from  the  folder  imap-folder-
              uri.     The    argument    must    be    an    IMAP    URI,   e.g.   “subscribe-to
              imaps://mail.example.org/inbox”.

              Subscription is an IMAP protocol  feature  where  the  server  manages  a  list  of
              subscribed folders.  This list can be queried by clients like NeoMutt.

              NeoMutt  uses  that  list  in  various  situations,  see  $imap_list_subscribed and
              $imap_check_subscribed.

       timeout-hook command
       startup-hook command
       shutdown-hook command

              The Global Hooks feature introduces these hooks to NeoMutt. They  are  called  when
              global events take place in NeoMutt. startup-hook and shutdown-hook are most likely
              to be useful to users of notmuch(1).

              timeout-hook runs a command periodically when NeoMutt checks  for  new  mail.  This
              hook is called every $timeout seconds.

              Before  NeoMutt  opens  the first mailbox when first starting, NeoMutt will run the
              startup-hook for the given command.

              Before NeoMutt is about to exit, and before the mailbox is closed, NeoMutt will run
              the shutdown-hook for the given command.

       unhook { * | hook-type }

              This command permits you to flush hooks you have previously defined. You can either
              remove all hooks by giving the “*” character as an argument, or you can remove  all
              hooks of a specific hook-type by saying something like “unhook send-hook”.

PATTERNS

   Pattern Modifier
       Many  of  NeoMutt's commands allow you to specify a pattern to match messages (limit, tag-
       pattern, delete-pattern, the above mentioned  hook  commands  etc.).  The  table  “Pattern
       modifiers” shows several ways to select messages.

       Special  attention  has  to  be  paid  when  using regular expressions inside of patterns.
       Specifically, NeoMutt's parser for these patterns will strip one level of backslash (“\”),
       which  is  normally  used  for  quoting. If it is your intention to use a backslash in the
       regular expression, you will need to use two backslashes (“\\”) instead.

       You can force NeoMutt to treat EXPR as a simple STRING instead of a regular expression  by
       using “=” instead of “~” in the pattern name. For example, “=b *.*” will find all messages
       that contain the literal STRING*.*”. Simple substring matches  are  less  powerful  than
       regular  expressions  but  can  be  considerably  faster. This is especially true for IMAP
       folders, because substring matches can be performed on the server instead of  by  fetching
       every  message. IMAP treats “=h” specially: it must be of the form “Header: substring” and
       will not partially match header names. The substring part may be  omitted  if  you  simply
       wish to find messages containing a particular header without regard to its value.

       Patterns matching lists of addresses (notably c, C, p, P and t) match if there is at least
       one match in the whole list. If you want to make sure  that  all  elements  of  that  list
       match, you need to prefix your pattern with “^”.

       This example matches all mails which only has recipients from Germany.

              Matching all addresses in address lists: ^~C \.de$

       You  can  restrict  address pattern matching to aliases that you have defined with the “@”
       modifier. This example matches messages whose recipients are all from Germany and who  are
       known to your alias list.

              Matching restricted to aliases: ^@~C \.de$

       To match any defined alias, use a regular expression that matches any string. This example
       matches messages whose senders are known aliases.

              Matching any defined alias: @~f .

   Nesting and Boolean Operators
       Logical AND is performed by specifying more than one criterion.

              For example: ~t work ~f smith

       would select messages which contain the word “work” in the list  of  recipients  and  that
       have the word “elkins” in the “From:” header field.

       NeoMutt also recognizes the following operators to create more complex search patterns:

              • “!” — logical NOT operator
              • “|” — logical OR operator
              • “()” — logical grouping operator

       Here  is  an  example  illustrating a complex search pattern. This pattern will select all
       messages which do not contain “work” in the “To:”  or  “Cc:”  field  and  which  are  from
       “elkins”.

              Using boolean operators in patterns: !(~t work|~c work) ~f smith

       Here  is  an  example  using  white  space in the regular expression (note the “'” and “"”
       delimiters). For this to match, the mail's subject must match the “^Junk +From  +Me$”  and
       it must be from either “Jim +Somebody” or “Ed +SomeoneElse”:

              Quoting regex: '~s "^Junk +From +Me$" ~f ("Jim +Somebody"|"Ed +SomeoneElse")'

       Note:  If  a  regular  expression  contains parenthesis, or a vertical bar (“|”), you must
       enclose the expression in double or single quotes since those characters are also used  to
       separate different parts of NeoMutt's pattern language.

              For example: ~f "user@(home\.org|work\.com)"

       Without  the  quotes,  the  parenthesis  wouldn't end. This would be separated to two OR'd
       patterns: ~f user@(home\.org and work\.com). They are never what you want.

   Searching by Date
       NeoMutt supports two types of dates, absolute and relative for the “~d” and “~r” pattern.

       Absolute Dates
       Dates must be in dd[/mm[/[CC]YY]] format (day, month, century and year — all  parts,  with
       the  exception of day, are optional, defaulting to the current month and year). An example
       of a valid range of dates is:

              Limit to messages matching: ~d 20/1/95-31/10

       Alternatively, you may use YYYYMMDD to specify a date.

       When given a two-digit year, NeoMutt will interpret values less than “70” as lying in  the
       21st  century  (i.e.,  “38” means 2038 and not 1938, and “00” is interpreted as 2000), and
       values greater than or equal to “70” as lying in the 20th century.

       If you omit the MINimum (first) date, and just specify -dd/mm/YY, all messages before  the
       given date will be selected. If you omit the MAXimum (second) date, and specify dd/mm/YY-,
       all messages after the given date will be selected. If you specify a single date  with  no
       dash (“-”), only messages sent/received on the given date will be selected.

       You  can  add  error  margins  to  absolute dates. An error margin is a sign (“+” or “-”),
       followed by a digit, followed by one of the units  in  table  “Date  units”  below.  As  a
       special  case,  you can replace the sign by a “*” character, which is equivalent to giving
       identical plus and minus error margins.

                       ┌─────────────┬──────┬───────┬────────┬───────┬───┬───┬───┐

       Example: To select any messages two weeks around January 15, 2001, you'd use the following
       pattern:

              Limit to messages matching: ~d 15/1/2001*2w

       It is possible to give multiple error margins:

              which cumulate: ~d 1/1/2001-1w+2w*3d

       Relative Dates
       This type of date is relative to the current date, and may be specified as:

              • “<offset” for messages newer than offset units
              • “=offset” for messages exactly offset units old
              • “>offset” for messages older than offset units

       offset is specified as a positive number with one of the units from table “Date units”.

       Example: To select messages less than 1 month old, you would use:

              Limit to messages matching: ~d <1m

       Note:  All  dates  used  when searching are relative to the local time zone, so unless you
       change the setting of your $index_format to include a “%[...]” format, these are  not  the
       dates shown in the main index.

CONFIGURATION VARIABLES

       abort_backspace
              Type: boolean
              Default: yes

              If set, hitting backspace against an empty prompt aborts the prompt.

       abort_key
              Type: string
              Default: "007"

              Specifies  the  key  that  can be used to abort prompts.  The format is the same as
              used in "bind" commands.  The default is equivalent to  "Ctrl-G".   Note  that  the
              specified  key  should  not  be  used in other bindings, as the abort operation has
              higher precedence and the binding will not have the desired effect.

              Example:

              set abort_key = "<Esc>"

              Please note that when using <Esc> as the abort key, you may also want  to  set  the
              environment  variable  ESCDELAY to a low value or even 0 which will reduce the time
              that ncurses waits to distinguish singular <Esc> key presses from the  start  of  a
              terminal  escape  sequence.  The  default  time is 1000 milliseconds and thus quite
              noticeable.

       abort_noattach
              Type: quadoption
              Default: no

              If set to yes, when composing messages containing the regular expression  specified
              by $abort_noattach_regex and no attachments are given, composition will be aborted.
              If set to no, composing messages as such will never be aborted.

              Example:

              set abort_noattach_regex = "\\<attach(|ed|ments?)\\>"

       abort_noattach_regex
              Type: regular expression
              Default: "\<(attach|attached|attachments?)\>"

              Specifies a regular expression to  match  against  the  body  of  the  message,  to
              determine  if an attachment was mentioned but mistakenly forgotten.  If it matches,
              $abort_noattach will be consulted to determine if message sending will be aborted.

              Like other regular expressions in NeoMutt, the search  is  case  sensitive  if  the
              pattern contains at least one upper case letter, and case insensitive otherwise.

       abort_nosubject
              Type: quadoption
              Default: ask-yes

              If  set  to  yes,  when  composing  messages and no subject is given at the subject
              prompt, composition will be aborted.  If set to  no,  composing  messages  with  no
              subject given at the subject prompt will never be aborted.

       abort_unmodified
              Type: quadoption
              Default: yes

              If  set to yes, composition will automatically abort after editing the message body
              if no changes are made to the file (this check only happens after the first edit of
              the file).  When set to no, composition will never be aborted.

       account_command
              Type: command
              Default: ""

              If  set,  this  command  is  used  to  retrieve account credentials. The command is
              invoked passing a number of --key value arguments with the specifics of the account
              to  lookup.  The  command  writes  to standard output a number of key: value lines.
              Currently supported arguments are --hostname, --username, and  --type,  where  type
              can  be  any  of  imap,  imaps,  pop, pops, smtp, smtps, nntp, and nntps. Currently
              supported output lines are login, username, and password.

       alias_file
              Type: path
              Default: "~/.neomuttrc"

              The default file in which to save aliases created by the  <create-alias>  function.
              Entries  added  to  this  file  are  encoded  in  the  character  set  specified by
              $config_charset if it is set or the current character set otherwise.

              Note: NeoMutt will not automatically source this file; you must explicitly use  the
              "source"  command  for  it to be executed in case this option points to a dedicated
              alias file.

              The default for this option is the currently used neomuttrc file, or "~/.neomuttrc"
              if no user neomuttrc was found.

       alias_format
              Type: string
              Default: "%3n %f%t %-15a %-56r | %c"

              Specifies  the  format  of  the data displayed for the "alias" menu.  The following
              printf(3)-style sequences are available:
              %a     Alias name
              %c     Comment
              %f     Flags - currently, a "d" for an alias marked for deletion
              %n     Index number
              %r     Address which alias expands to
              %t     Character which indicates if the alias is tagged for inclusion
              %>X    right justify the rest of the string and pad with character "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

       allow_8bit
              Type: boolean
              Default: yes

              Controls whether 8-bit data is converted to 7-bit using either Quoted- Printable or
              Base64 encoding when sending mail.

       allow_ansi
              Type: boolean
              Default: no

              Controls  whether  ANSI  color  codes  in  messages  (and  color  tags in rich text
              messages) are to be interpreted.  Messages containing these codes are rare, but  if
              this  option  is  set,  their  text will be colored accordingly. Note that this may
              override your color choices, and even present a security problem, since  a  message
              could include a line like

              [-- PGP output follows ...

              and give it the same color as your attachment color (see also $crypt_timestamp).

       arrow_cursor
              Type: boolean
              Default: no

              When  set,  an  arrow  ("->")  will  be used to indicate the current entry in menus
              instead of highlighting the whole line.  On slow network or modem links  this  will
              make  response  faster  because  there is less that has to be redrawn on the screen
              when moving to the next or previous entries in the menu.

       arrow_string
              Type: string
              Default: "->"

              Specifies the string of arrow_cursor when arrow_cursor enabled.

       ascii_chars
              Type: boolean
              Default: no

              If set, NeoMutt  will  use  plain  ASCII  characters  when  displaying  thread  and
              attachment trees, instead of the default ACS characters.

       ask_bcc
              Type: boolean
              Default: no

              If  set,  NeoMutt  will  prompt  you  for blind-carbon-copy (Bcc) recipients before
              editing an outgoing message.

       ask_cc
              Type: boolean
              Default: no

              If set, NeoMutt will prompt you for carbon-copy (Cc) recipients before editing  the
              body of an outgoing message.

       ask_followup_to
              Type: boolean
              Default: no

              If  set, NeoMutt will prompt you for follow-up groups before editing the body of an
              outgoing message.

       ask_x_comment_to
              Type: boolean
              Default: no

              If set, NeoMutt will prompt you for x-comment-to field before editing the  body  of
              an outgoing message.

       assumed_charset
              Type: string list
              Default: ""

              This  variable is a colon-separated list of character encoding schemes for messages
              without character encoding  indication.   Header  field  values  and  message  body
              content  without  character  encoding  indication  would  be  assumed that they are
              written in one of this list.  By default, all the header fields  and  message  body
              without any charset indication are assumed to be in "us-ascii".

              For example, Japanese users might prefer this:

              set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"

              However, only the first content is valid for the message body.

       attach_charset
              Type: string list
              Default: ""

              This variable is a colon-separated list of character encoding schemes for text file
              attachments. NeoMutt uses this setting to guess which encoding files being attached
              are encoded in to convert them to a proper character set given in $send_charset.

              If  unset,  the value of $charset will be used instead.  For example, the following
              configuration would work for Japanese text handling:

              set attach_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"

              Note: for Japanese users, "iso-2022-*" must be put at the  head  of  the  value  as
              shown above if included.

       attach_format
              Type: string
              Default: "%u%D%I %t%4n %T%d %> [%.7m/%.10M, %.6e%<C?, %C>, %s] "

              This  variable  describes  the  format  of  the  "attachment"  menu.  The following
              printf(3)-style sequences are understood:
              %C     Charset
              %c     Requires charset conversion ("n" or "c")
              %D     Deleted flag
              %d     Description (if none, falls back to %F)
              %e     MIME content-transfer-encoding
              %f     Filename
              %F     Filename in content-disposition header (if none, falls back to %f)
              %I     Disposition ("I" for inline, "A" for attachment)
              %m     Major MIME type
              %M     MIME subtype
              %n     Attachment number
              %Q     "Q", if MIME part qualifies for attachment counting
              %s     Size (see formatstrings-size)
              %T     Graphic tree characters
              %t     Tagged flag
              %u     Unlink (=to delete) flag
              %X     Number of qualifying MIME parts in this part and its  children  (please  see
                     the "attachments" section for possible speed effects)
              %>X    Right justify the rest of the string and pad with character "X"
              %|X    Pad to the end of the line with character "X"
              %*X    Soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the $index_format documentation.

       attach_save_dir
              Type: path
              Default: "./"

              The directory where attachments are saved.

       attach_save_without_prompting
              Type: boolean
              Default: no

              This  variable,  when  set  to  true,  will  cause  attachments  to be saved to the
              'attach_save_dir' location without prompting the user for the filename.

       attach_sep
              Type: string
              Default: "\n"

              The separator to add between attachments when operating (saving, printing,  piping,
              etc) on a list of tagged attachments.

       attach_split
              Type: boolean
              Default: yes

              If this variable is unset, when operating (saving, printing, piping, etc) on a list
              of tagged attachments, NeoMutt will concatenate the attachments and will operate on
              them  as  a  single  attachment.  The  $attach_sep  separator  is  added after each
              attachment. When set, NeoMutt will operate on the attachments one by one.

       attribution_intro
              Type: string
              Default: "On %d, %n wrote:"

              This is the string that will precede a replied-to message which is  quoted  in  the
              main body of the reply (this is the case when $include is set).

              For  a  full  listing  of  defined  printf(3)-like  sequences  see  the  section on
              $index_format.  See also $attribution_locale.

       attribution_locale
              Type: string
              Default: ""

              The locale used by strftime(3) to format dates in the attribution  strings.   Legal
              values  are  the  strings  your  system accepts for the locale environment variable
              $LC_TIME.

              This variable is to allow the attribution date format to be customized by recipient
              or  folder  using  hooks.  By default, NeoMutt will use your locale environment, so
              there is no need to set this except to override that default.

              Affected     variables     are:      $attribution_intro,      $attribution_trailer,
              $forward_attribution_intro, $forward_attribution_trailer, $indent_string.

       attribution_trailer
              Type: string
              Default: ""

              Similar to the $attribution_intro variable, this is the string that will come after
              a replied-to message which is quoted in the main body of the  reply  (this  is  the
              case when $include is set).

              For  a  full  listing  of  defined  printf(3)-like  sequences  see  the  section on
              $index_format.  See also $attribution_locale.

       auto_edit
              Type: boolean
              Default: no

              When set  along  with  $edit_headers,  NeoMutt  will  skip  the  initial  send-menu
              (prompting  for  subject and recipients) and allow you to immediately begin editing
              the body of your message.  The send-menu  may  still  be  accessed  once  you  have
              finished editing the body of your message.

              Note:  when  this  option  is  set,  you  can't  use  send-hooks that depend on the
              recipients when composing a  new  (non-reply)  message,  as  the  initial  list  of
              recipients is empty.

              Also see $fast_reply.

       auto_subscribe
              Type: boolean
              Default: no

              When set, NeoMutt assumes the presence of a List-Post header means the recipient is
              subscribed to the list.  Unless  the  mailing  list  is  in  the  "unsubscribe"  or
              "unlist"  lists,  it  will  be added to the "subscribe" list.  Parsing and checking
              these things slows header reading down, so this option is disabled by default.

       auto_tag
              Type: boolean
              Default: no

              When set, functions in the index menu which affect a message will be applied to all
              tagged  messages  (if  there  are  any).   When  unset,  you  must  first  use  the
              <tag-prefix> function (bound to ";" by default) to make the next function apply  to
              all tagged messages.

       autocrypt
              Type: boolean
              Default: no

              When set, enables autocrypt, which provides passive encryption protection with keys
              exchanged via headers.  See "autocryptdoc" for more details.  (Autocrypt only)

       autocrypt_acct_format
              Type: string
              Default: "%4n %-30a %20p %10s"

              This variable describes the format of the "autocrypt account" menu.  The  following
              printf(3)-style sequences are understood
              %a     email address
              %k     gpg keyid
              %n     current entry number
              %p     prefer-encrypt flag
              %s     status flag (active/inactive)

              (Autocrypt only)

       autocrypt_dir
              Type: path
              Default: "~/.mutt/autocrypt"

              This  variable sets where autocrypt files are stored, including the GPG keyring and
              SQLite database.  See "autocryptdoc" for more details.  (Autocrypt only)

       autocrypt_reply
              Type: boolean
              Default: yes

              When set, replying to an autocrypt email automatically  enables  autocrypt  in  the
              reply.   You  may  want to unset this if you're using the same key for autocrypt as
              normal web-of-trust, so that autocrypt isn't forced on for all  encrypted  replies.
              (Autocrypt only)

       beep
              Type: boolean
              Default: yes

              When this variable is set, NeoMutt will beep when an error occurs.

       beep_new
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will beep whenever it prints a message notifying
              you of new mail.  This is independent of the setting of the $beep variable.

       bounce
              Type: quadoption
              Default: ask-yes

              Controls whether you will be asked to confirm bouncing messages.  If set to yes you
              don't get asked if you want to bounce a message. Setting this variable to no is not
              generally useful, and thus not  recommended,  because  you  are  unable  to  bounce
              messages.

       bounce_delivered
              Type: boolean
              Default: yes

              When  this variable is set, NeoMutt will include Delivered-To headers when bouncing
              messages.  Postfix users may wish to unset this variable.

              Note: On Debian systems, this option is unset by default in /etc/Muttrc.

       braille_friendly
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will place the cursor at the  beginning  of  the
              current  line  in  menus,  even when the $arrow_cursor variable is unset, making it
              easier for blind persons using Braille displays to follow these menus.  The  option
              is  unset  by  default because many visual terminals don't permit making the cursor
              invisible.

       browser_abbreviate_mailboxes
              Type: boolean
              Default: yes

              When this variable is set, NeoMutt will abbreviate mailbox  names  in  the  browser
              mailbox list, using '~' and '=' shortcuts.

              The  default  "alpha"  setting  of  $sort_browser  uses locale-based sorting (using
              strcoll(3)), which ignores some punctuation.  This  can  lead  to  some  situations
              where  the order doesn't make intuitive sense.  In those cases, it may be desirable
              to unset this variable.

       catchup_newsgroup
              Type: quadoption
              Default: ask-yes

              If this variable is set, NeoMutt will mark all articles in newsgroup as  read  when
              you quit the newsgroup (catchup newsgroup).

       certificate_file
              Type: path
              Default: "~/.mutt_certificates"

              This  variable  specifies the file where the certificates you trust are saved. When
              an unknown certificate is encountered, you are asked if you accept it  or  not.  If
              you  accept  it,  the  certificate  can  also  be  saved  in  this file and further
              connections are automatically accepted.

              You can also manually add CA certificates in this file. Any server certificate that
              is signed with one of these CA certificates is also automatically accepted.

              Example:

              set certificate_file=~/.neomutt/certificates

       change_folder_next
              Type: boolean
              Default: no

              When  this  variable  is  set, the <change-folder> function mailbox suggestion will
              start at the next folder in your "mailboxes" list, instead of starting at the first
              folder in the list.

       charset
              Type: string
              Default: ""

              Character set your terminal uses to display and enter textual data.  It is also the
              fallback for $send_charset.

              Upon startup NeoMutt tries to derive this value from environment variables such  as
              $LC_CTYPE or $LANG.

              Note:  It  should only be set in case NeoMutt isn't able to determine the character
              set used correctly.

       check_mbox_size
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will use file size attribute instead  of  access
              time when checking for new mail in mbox and mmdf folders.

              This  variable  is  unset  by  default  and  should  only  be enabled when new mail
              detection for these folder types is unreliable or doesn't work.

              Note that enabling this variable should happen before  any  "mailboxes"  directives
              occur  in  configuration files regarding mbox or mmdf folders because NeoMutt needs
              to determine the initial new mail status of such a mailbox  by  performing  a  fast
              mailbox scan when it is defined.  Afterwards the new mail status is tracked by file
              size changes.

       check_new
              Type: boolean
              Default: yes

              Note: this option only affects maildir and MH style mailboxes.

              When set, NeoMutt will check for new mail delivered  while  the  mailbox  is  open.
              Especially  with  MH  mailboxes,  this  operation can take quite some time since it
              involves scanning the directory and checking each file to see  if  it  has  already
              been  looked  at.   If  this  variable is unset, no check for new mail is performed
              while the mailbox is open.

       collapse_all
              Type: boolean
              Default: no

              When set, NeoMutt will collapse all threads when entering a folder.

       collapse_flagged
              Type: boolean
              Default: yes

              When unset, NeoMutt will not collapse a thread if it contains any flagged messages.

       collapse_unread
              Type: boolean
              Default: yes

              When unset, NeoMutt will not collapse a thread if it contains any unread messages.

       color_directcolor
              Type: boolean
              Default: no

              When set, NeoMutt will use and allow 24bit colours (aka truecolor aka directcolor).
              For  colours  to  work  properly support from the terminal is required as well as a
              properly set  TERM  environment  variable  advertising  the  terminals  directcolor
              capability, e.g. "TERM=xterm-direct".

              NeoMutt  tries  to  detect  whether the terminal supports 24bit colours and enables
              this variable if it does.  If this fails for  some  reason,  you  can  force  24bit
              colours  by  setting  this  variable manually.  You may also try to force a certain
              TERM environment variable by starting NeoMutt from  a  terminal  as  follows  (this
              results in wrong colours if the terminal does not implement directcolors):

              TERM=xterm-direct neomutt

              Note: This variable must be set before using any `color` commands.

       compose_format
              Type: string
              Default: "-- NeoMutt: Compose  [Approx. msg size: %l   Atts: %a]%>-"

              Controls  the  format  of  the  status  line displayed in the "compose" menu.  This
              string is similar  to  $status_format,  but  has  its  own  set  of  printf(3)-like
              sequences:
              %a     Total number of attachments
              %h     Local hostname
              %l     Approximate size (in bytes) of the current message (see formatstrings-size)
              %v     NeoMutt version string
              %>X    right justify the rest of the string and pad with character "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

              See  the  text  describing the $status_format option for more information on how to
              set $compose_format.

       compose_show_user_headers
              Type: boolean
              Default: yes

              When set, Neomutt will display user-defined headers (set via my_hdr or from editing
              with edit-headers).

       config_charset
              Type: string
              Default: ""

              When  defined,  NeoMutt  will recode commands in rc files from this encoding to the
              current character set as specified by $charset and aliases written  to  $alias_file
              from the current character set.

              Please   note   that   if   setting   $charset  it  must  be  done  before  setting
              $config_charset.

              Recoding should be avoided as it may render unconvertable  characters  as  question
              marks   which   can  lead  to  undesired  side  effects  (for  example  in  regular
              expressions).

       confirm_append
              Type: boolean
              Default: yes

              When set, NeoMutt will prompt  for  confirmation  when  appending  messages  to  an
              existing mailbox.

       confirm_create
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will prompt for confirmation when saving messages to a mailbox
              which does not yet exist before creating it.

       content_type
              Type: string
              Default: "text/plain"

              Sets the default Content-Type for the body of newly composed messages.

       copy
              Type: quadoption
              Default: yes

              This variable controls whether or not copies of  your  outgoing  messages  will  be
              saved  for  later  references.  Also see $record, $save_name, $force_name and "fcc-
              hook".

       copy_decode_weed
              Type: boolean
              Default: no

              Controls whether NeoMutt will weed  headers  when  invoking  the  <decode-copy>  or
              <decode-save> functions.

       count_alternatives
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  recurse  inside  multipart/alternatives while performing
              attachment searching and counting(see attachments).

              Traditionally,  multipart/alternative  parts  have  simply  represented   different
              encodings  of the main content of the email.  Unfortunately, some mail clients have
              started to place email attachments inside one of alternatives.  Setting  this  will
              allow NeoMutt to find and count matching attachments hidden there, and include them
              in the index via %X or through ~X pattern matching.

       crypt_auto_encrypt
              Type: boolean
              Default: no

              Setting this variable will cause NeoMutt to always attempt to PGP encrypt  outgoing
              messages.   This  is probably only useful in connection to the "send-hook" command.
              It can be overridden by use of the pgp menu, when encryption  is  not  required  or
              signing  is  requested  as well.  If $smime_is_default is set, then OpenSSL is used
              instead to create S/MIME messages and settings can be  overridden  by  use  of  the
              smime menu instead.  (Crypto only)

       crypt_auto_pgp
              Type: boolean
              Default: yes

              This  variable  controls  whether  or  not  NeoMutt  may  automatically  enable PGP
              encryption/signing     for     messages.      See     also     $crypt_auto_encrypt,
              $crypt_reply_encrypt, $crypt_auto_sign, $crypt_reply_sign and $smime_is_default.

       crypt_auto_sign
              Type: boolean
              Default: no

              Setting  this  variable  will  cause NeoMutt to always attempt to cryptographically
              sign outgoing messages.  This can be overridden  by  use  of  the  pgp  menu,  when
              signing is not required or encryption is requested as well. If $smime_is_default is
              set, then OpenSSL is used instead to create S/MIME messages  and  settings  can  be
              overridden by use of the smime menu instead of the pgp menu.  (Crypto only)

       crypt_auto_smime
              Type: boolean
              Default: yes

              This  variable  controls  whether  or  not  NeoMutt may automatically enable S/MIME
              encryption/signing     for     messages.     See     also      $crypt_auto_encrypt,
              $crypt_reply_encrypt, $crypt_auto_sign, $crypt_reply_sign and $smime_is_default.

       crypt_chars
              Type: character string
              Default: "SPsK "

              Controls the characters used in cryptography flags.
              Character
                     Default Description
              1      S The mail is signed, and the signature is successfully verified.
              2      P The mail is PGP encrypted.
              3      s The mail is signed.
              4      K The mail contains a PGP public key.
              5      <space> The mail has no crypto info.

       crypt_confirm_hook
              Type: boolean
              Default: yes

              If  set,  then  you  will  be  prompted  for  confirmation  of  keys when using the
              crypt-hook command.  If unset, no such confirmation prompt will be presented.  This
              is generally considered unsafe, especially where typos are concerned.

       crypt_opportunistic_encrypt
              Type: boolean
              Default: no

              Setting  this  variable  will  cause  NeoMutt  to  automatically enable and disable
              encryption, based on whether all message recipient keys can be located by NeoMutt.

              When this option is enabled, NeoMutt will enable/disable encryption each  time  the
              TO, CC, and BCC lists are edited.  If $edit_headers is set, NeoMutt will also do so
              each time the message is edited.

              While this is set, encryption can't be manually enabled/disabled.  The pgp or smime
              menus  provide  a  selection  to  temporarily  disable  this option for the current
              message.

              If $crypt_auto_encrypt or $crypt_reply_encrypt enable  encryption  for  a  message,
              this  option  will  be disabled for that message.  It can be manually re-enabled in
              the pgp or smime menus.  (Crypto only)

       crypt_opportunistic_encrypt_strong_keys
              Type: boolean
              Default: no

              When set, this modifies the behavior of $crypt_opportunistic_encrypt to only search
              for  "strong  keys", that is, keys with full validity according to the web-of-trust
              algorithm.  A key with marginal  or  no  validity  will  not  enable  opportunistic
              encryption.

              For  S/MIME,  the  behavior depends on the backend.  Classic S/MIME will filter for
              certificates with the 't'(trusted) flag in the .index file.  The GPGME backend will
              use  the  same  filters as with OpenPGP, and depends on GPGME's logic for assigning
              the GPGME_VALIDITY_FULL and GPGME_VALIDITY_ULTIMATE validity flag.

       crypt_protected_headers_read
              Type: boolean
              Default: yes

              When set, NeoMutt will display protected headers ("Memory Hole") in the pager, When
              set, NeoMutt will display protected headers in the pager, and will update the index
              and header cache with revised headers.

              Protected headers are stored inside the encrypted or signed part of an an email, to
              prevent     disclosure     or     tampering.      For    more    information    see
              https://github.com/autocrypt/protected-headers Currently NeoMutt only supports  the
              Subject header.

              Encrypted  messages  using  protected  headers often substitute the exposed Subject
              header with a dummy value  (see  $crypt_protected_headers_subject).   NeoMutt  will
              update its concept of the correct subject after the message is opened, i.e. via the
              <display-message> function.  If you reply to a message before opening  it,  NeoMutt
              will  end  up  using  the  dummy  Subject header, so be sure to open such a message
              first.  (Crypto only)

       crypt_protected_headers_save
              Type: boolean
              Default: no

              When $crypt_protected_headers_read is set, and a message with a  protected  Subject
              is  opened, NeoMutt will save the updated Subject into the header cache by default.
              This allows searching/limiting based on the protected Subject header if the mailbox
              is  re-opened,  without  having  to  re-open  the  message each time.  However, for
              mbox/mh mailbox types, or if header caching is  not  set  up,  you  would  need  to
              re-open  the  message  each  time  the mailbox was reopened before you could see or
              search/limit on the protected subject again.

              When this variable is set, NeoMutt additionally saves the protected Subject back in
              the  clear-text  message  headers.   This  provides  better usability, but with the
              tradeoff of reduced  security.   The  protected  Subject  header,  which  may  have
              previously  been  encrypted,  is  now  stored in clear-text in the message headers.
              Copying the message elsewhere, via NeoMutt or external  tools,  could  expose  this
              previously  encrypted  data.   Please  make sure you understand the consequences of
              this before you enable this variable.  (Crypto only)

       crypt_protected_headers_subject
              Type: string
              Default: "..."

              When  $crypt_protected_headers_write  is  set,  and  the  message  is  marked   for
              encryption, this will be substituted into the Subject field in the message headers.

              To  prevent a subject from being substituted, unset this variable, or set it to the
              empty string.  (Crypto only)

       crypt_protected_headers_write
              Type: boolean
              Default: no

              When set, NeoMutt will generate protected headers for signed and encrypted emails.

              Protected headers are stored inside the encrypted or signed part of an an email, to
              prevent     disclosure     or     tampering.      For    more    information    see
              https://github.com/autocrypt/protected-headers

              Currently NeoMutt only supports the Subject header.  (Crypto only)

       crypt_reply_encrypt
              Type: boolean
              Default: yes

              If set, automatically  PGP  or  OpenSSL  encrypt  replies  to  messages  which  are
              encrypted.  (Crypto only)

       crypt_reply_sign
              Type: boolean
              Default: no

              If set, automatically PGP or OpenSSL sign replies to messages which are signed.

              Note: this does not work on messages that are encrypted and signed!  (Crypto only)

       crypt_reply_sign_encrypted
              Type: boolean
              Default: no

              If  set, automatically PGP or OpenSSL sign replies to messages which are encrypted.
              This makes sense in combination with $crypt_reply_encrypt, because it allows you to
              sign all messages which are automatically encrypted.  This works around the problem
              noted in $crypt_reply_sign, that NeoMutt  is  not  able  to  find  out  whether  an
              encrypted message is also signed.  (Crypto only)

       crypt_timestamp
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will include a time stamp in the lines surrounding PGP or S/MIME
              output, so spoofing such lines is more difficult.  If you are using colors to  mark
              these lines, and rely on these, you may unset this setting.  (Crypto only)

       crypt_use_gpgme
              Type: boolean
              Default: yes

              This  variable controls the use of the GPGME-enabled crypto backends.  If it is set
              and NeoMutt was built with GPGME support, the gpgme code for S/MIME and PGP will be
              used  instead  of  the  classic  code.   Note  that  you need to set this option in
              .neomuttrc; it won't have any effect when used interactively.

              Note  that  the  GPGME  backend  does  not  support   creating   old-style   inline
              (traditional) PGP encrypted or signed messages (see $pgp_auto_inline).

       crypt_use_pka
              Type: boolean
              Default: no

              Controls whether NeoMutt uses PKA (see http://www.g10code.de/docs/pka-intro.de.pdf)
              during signature verification (only supported by the GPGME backend).

       crypt_verify_sig
              Type: quadoption
              Default: yes

              If "yes", always attempt to verify PGP  or  S/MIME  signatures.   If  "ask-*",  ask
              whether  or  not  to  verify  the  signature.   If  "no",  never  attempt to verify
              cryptographic signatures.  (Crypto only)

       date_format
              Type: string
              Default: "!%a, %b %d, %Y at %I:%M:%S%p %Z"

              Instead of using $date_format it is encouraged to  use  "%[fmt]"  directly  in  the
              corresponding  format  strings,  where  "fmt"  is  the value of $date_format.  This
              allows for a more fine grained control of the different menu needs.

              This variable controls the format of the date  printed  by  the  "%d"  sequence  in
              $index_format.  This is passed to the strftime(3) function to process the date, see
              the man page for the proper syntax.

              Unless the first character in the string is a bang ("!"), the month  and  week  day
              names  are  expanded according to the locale.  If the first character in the string
              is a bang, the bang is discarded, and the month and week day names in the  rest  of
              the string are expanded in the C locale (that is in US English).

              Format strings using this variable are:

              UI:   $folder_format,   $index_format,  $mailbox_folder_format,  $message_format.IP
              Composing:             $attribution_intro,              $forward_attribution_intro,
              $forward_attribution_trailer, $forward_format, $indent_string.

       debug_file
              Type: path
              Default: "~/.neomuttdebug"

              Debug  logging  is  controlled  by  the  variables  $debug_file  and  $debug_level.
              $debug_file specifies the root of the filename.  NeoMutt will add "0" to  the  end.
              Each  time  NeoMutt  is  run  with  logging  enabled, the log files are rotated.  A
              maximum of five log files are kept, numbered 0 (most recent) to 4 (oldest).

              This option can be enabled on the command line, "neomutt -l mylog"

              See also: $debug_level

       debug_level
              Type: number
              Default: 0

              Debug logging is controlled by the variables $debug_file and $debug_level.

              The debug level controls how much information is saved to the  log  file.   If  you
              have a problem with NeoMutt, then enabling logging may help find the cause.  Levels
              1-3 will usually provide enough information for writing a bug report.   Levels  4,5
              will be extremely verbose.

              Warning: Logging at high levels may save private information to the file.

              This option can be enabled on the command line, "neomutt -d 2"

              See also: $debug_file

       default_hook
              Type: string
              Default: "~f %s !~P | (~P ~C %s)"

              This  variable  controls how some hooks are interpreted if their pattern is a plain
              string or a regex. i.e. they don't contain a pattern, like ~f

              The hooks are: fcc-hook,  fcc-save-hook,  index-format-hook,  message-hook,  reply-
              hook, save-hook, send-hook and send2-hook.

              The  hooks  are  expanded  when  they  are  declared, so a hook will be interpreted
              according to the value of this variable at the time the hook is declared.

              The default value matches if the message is either from a user matching the regular
              expression  given,  or if it is from you (if the from address matches "alternates")
              and is to or cc'ed to a user matching the given regular expression.

       delete
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are really deleted when closing or synchronizing a
              mailbox.   If set to yes, messages marked for deleting will automatically be purged
              without prompting.  If set to no, messages marked for deletion will be kept in  the
              mailbox.

       delete_untag
              Type: boolean
              Default: yes

              If  this option is set, NeoMutt will untag messages when marking them for deletion.
              This applies when you either explicitly delete a message, or when you  save  it  to
              another folder.

       digest_collapse
              Type: boolean
              Default: yes

              If  this  option  is  set,  NeoMutt's  received-attachments  menu will not show the
              subparts of individual messages in a  multipart/digest.   To  see  these  subparts,
              press "v" on that menu.

       display_filter
              Type: command
              Default: ""

              When set, specifies a command used to filter messages.  When a message is viewed it
              is passed as standard input to $display_filter, and the filtered  message  is  read
              from the standard output.

              When  preparing  the  message, NeoMutt inserts some escape sequences into the text.
              They are of the form: <esc>]9;XXX<bel> where "XXX" is a random 64-bit number.

              If these escape sequences interfere with your filter, they can be removed  using  a
              tool like ansifilter or sed 's/^\x1b]9;[0-9]\+\x7//'

              If  they  are  removed, then PGP and MIME headers will no longer be coloured.  This
              can be fixed by adding this to your config: color body magenta  default  '^\[--  .*
              --\]$'.

       dsn_notify
              Type: string
              Default: ""

              This  variable  sets  the  request  for  when notification is returned.  The string
              consists of a comma separated list (no spaces!) of one or more  of  the  following:
              never,   to  never  request  notification,  failure,  to  request  notification  on
              transmission failure, delay, to be notified  of  message  delays,  success,  to  be
              notified of successful transmission.

              Example:

              set dsn_notify="failure,delay"

              Note:  when using $sendmail for delivery, you should not enable this unless you are
              either using Sendmail 8.8.x or greater or a MTA providing a  sendmail(1)-compatible
              interface  supporting  the  -N  option  for  DSN. For SMTP delivery, DSN support is
              auto-detected so that it depends on the server whether DSN will be used or not.

       dsn_return
              Type: string
              Default: ""

              This variable controls how much of your message is returned in  DSN  messages.   It
              may  be set to either hdrs to return just the message header, or full to return the
              full message.

              Example:

              set dsn_return=hdrs

              Note: when using $sendmail for delivery, you should not enable this unless you  are
              either  using Sendmail 8.8.x or greater or a MTA providing a sendmail(1)-compatible
              interface supporting the -R option for DSN.  For  SMTP  delivery,  DSN  support  is
              auto-detected so that it depends on the server whether DSN will be used or not.

       duplicate_threads
              Type: boolean
              Default: yes

              This  variable  controls  whether  NeoMutt,  when  $sort is set to threads, threads
              messages with the same Message-Id together.  If it is set, it will indicate that it
              thinks they are duplicates of each other with an equals sign in the thread tree.

       edit_headers
              Type: boolean
              Default: no

              This  option allows you to edit the header of your outgoing messages along with the
              body of your message.

              Although the compose menu may have localized header labels, the  labels  passed  to
              your  editor  will be standard RFC2822 headers, (e.g. To:, Cc:, Subject:).  Headers
              added in your editor must also be RFC2822 headers, or one  of  the  pseudo  headers
              listed in "edit-header".  NeoMutt will not understand localized header labels, just
              as it would not when parsing an actual email.

              Note that changes made to  the  References:  and  Date:  headers  are  ignored  for
              interoperability reasons.

       editor
              Type: command
              Default: ""

              This  variable specifies which editor is used by NeoMutt.  It defaults to the value
              of  the  $VISUAL,  or   $EDITOR,   environment   variable,   or   to   the   string
              "/usr/bin/editor" if neither of those are set.

              The  $editor  string may contain a %s escape, which will be replaced by the name of
              the file to be edited.  If the %s escape does not appear in $editor,  a  space  and
              the name to be edited are appended.

              The resulting string is then executed by running

              sh -c 'string'

              where string is the expansion of $editor described above.

       empty_subject
              Type: string
              Default: "Re: your mail"

              This  variable  specifies  the subject to be used when replying to an email with an
              empty subject.  It defaults to "Re: your mail".

       encode_from
              Type: boolean
              Default: no

              When set, NeoMutt will quoted-printable  encode  messages  when  they  contain  the
              string  "From  "  (note  the  trailing  space) in the beginning of a line.  This is
              useful to avoid the tampering certain mail delivery and transport agents tend to do
              with  messages  (in  order to prevent tools from misinterpreting the line as a mbox
              message separator).

       entropy_file
              Type: path
              Default: ""

              The file which includes  random  data  that  is  used  to  initialize  SSL  library
              functions.

       envelope_from_address
              Type: e-mail address
              Default: ""

              Manually  sets the envelope sender for outgoing messages.  This value is ignored if
              $use_envelope_from is unset.

       external_search_command
              Type: command
              Default: ""

              If set, contains the name of the external program used by "~I" patterns.  This will
              usually  be  a  wrapper  script  around  mairix, mu, or similar indexers other than
              notmuch (for which there is optional special support).

              Here is an example how it works.  Let's assume $external_search_command is  set  to
              "mairix_filter",  and  mairix_filter  is a script which runs the old but well loved
              mairix indexer with the arguments given to mairix_filter,  in  the  "raw"  mode  of
              mairix, producing on the standard output a list of Message-IDs, one per line.

              If  possible,  it  also  filters down the results coming from mairix such that only
              messages in the current folder remain.  It can do this because  it  gets  a  hidden
              first argument which is the path to the folder.  (This can be the type of clean and
              simple script called a one-liner.)

              Now if NeoMutt gets a limit  or  tag  command  followed  by  the  pattern  "~I  '-t
              s:bleeping='",  mairix_filter runs mairix with the arguments from inside the quotes
              (the quotes are needed because of the space after "-t"), mairix finds all  messages
              with  "bleeping"  in  the  Subject plus all messages sharing threads with these and
              outputs their  file  names,  and  mairix_filter  translates  the  file  names  into
              Message-IDs.   Finally,  NeoMutt  reads  the  Message-IDs  and targets the matching
              messages with the command given to it.

              You, the user, still have to rewrite the mairix_filter script to match the behavior
              of  your  indexer,  but  this  should  help users of indexers other than notmuch to
              integrate them cleanly with NeoMutt.

       fast_reply
              Type: boolean
              Default: no

              When set, the initial prompt for recipients (to, cc, bcc) and subject  are  skipped
              when the relevant information is already provided.  These cases include replying to
              messages and passing the relevant command line arguments. The  initial  prompt  for
              recipients  is  also  skipped  when  composing a new message to the current message
              sender, while the initial prompt  for  subject  is  also  skipped  when  forwarding
              messages.

              Note: this variable has no effect when the $auto_edit variable is set.

              See also: $auto_edit, $edit_headers, $ask_cc, $ask_bcc

       fcc_attach
              Type: quadoption
              Default: yes

              This  variable  controls  whether or not attachments on outgoing messages are saved
              along with the main body of your message.

              Note: $fcc_before_send forces the default (set) behavior of this option.

       fcc_before_send
              Type: boolean
              Default: no

              When this variable is set, FCCs will occur  before  sending  the  message.   Before
              sending,  the message cannot be manipulated, so it will be stored the exact same as
              sent: $fcc_attach and $fcc_clear will be ignored (using their default values).

              When unset, the default, FCCs will occur after sending.  Variables $fcc_attach  and
              $fcc_clear  will  be  respected,  allowing  it  to be stored without attachments or
              encryption/signing if desired.

       fcc_clear
              Type: boolean
              Default: no

              When this variable is set, FCCs will be stored unencrypted and unsigned, even  when
              the actual message is encrypted and/or signed.

              Note:  $fcc_before_send  forces  the default (unset) behavior of this option.  (PGP
              only)

              See also $pgp_self_encrypt, $smime_self_encrypt

       flag_chars
              Type: character string
              Default: "*!DdrONon- "

              Controls the characters used in several flags.
              Character
                     Default Description
              1      * The mail is tagged.
              2      !  The mail is flagged as important.
              3      D The mail is marked for deletion.
              4      d The mail has attachments marked for deletion.
              5      r The mail has been replied to.
              6      O The mail is Old (Unread but seen).
              7      N The mail is New (Unread but not seen).
              8      o The mail thread is Old (Unread but seen).
              9      n The mail thread is New (Unread but not seen).
              10     - The mail is read - %S expando.
              11     <space> The mail is read - %Z expando.

       flag_safe
              Type: boolean
              Default: no

              If set, flagged messages can't be deleted.

       folder
              Type: mailbox
              Default: "~/Mail"

              Specifies the default location of your mailboxes.  A "+" or "=" at the beginning of
              a pathname will be expanded to the value of this variable.  Note that if you change
              this variable (from the default) value you need to make sure  that  the  assignment
              occurs  before  you  use  "+"  or "=" for any other variables since expansion takes
              place when handling the "mailboxes" command.

       folder_format
              Type: string
              Default: "%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %i"

              This variable allows you to customize the file browser  display  to  your  personal
              taste.   This  string  is  similar  to  $index_format,  but  has  its  own  set  of
              printf(3)-like sequences:
              %C

                     Current file number
              %d

                     Date/time folder was last modified
              %D

                     Date/time folder was last modified using $date_format.  It is encouraged  to
                     use "%[fmt]" instead, where "fmt" is the value of $date_format.
              %f

                     Filename  ("/" is appended to directory names, "@" to symbolic links and "*"
                     to executable files)
              %F

                     File permissions
              %g

                     Group name (or numeric gid, if missing)
              %i

                     Description of the folder
              %l

                     Number of hard links
              %m     * Number of messages in the mailbox
              %n     * Number of unread messages in the mailbox
              %N

                     "N" if mailbox has new mail, " " (space) otherwise
              %s

                     Size in bytes (see formatstrings-size)
              %t

                     "*" if the file is tagged, blank otherwise
              %u

                     Owner name (or numeric uid, if missing)
              %[fmt]

                     Date/time folder was last modified using an strftime(3) expression
              %>X

                     Right justify the rest of the string and pad with character "X"
              %|X

                     Pad to the end of the line with character "X"
              %*X

                     Soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the $index_format documentation.

              * = can be optionally printed if nonzero

              %m, %n, and %N only work for monitored mailboxes.  %m requires $mail_check_stats to
              be set.  %n requires $mail_check_stats to be set (except for IMAP mailboxes).

       followup_to
              Type: boolean
              Default: yes

              Controls  whether  or  not  the  "Mail-Followup-To:" header field is generated when
              sending mail.  When set, NeoMutt will generate this field when you are replying  to
              a known mailing list, specified with the "subscribe" or "lists" commands.

              This field has two purposes.  First, preventing you from receiving duplicate copies
              of replies to messages which you send to mailing lists, and second,  ensuring  that
              you do get a reply separately for any messages sent to known lists to which you are
              not subscribed.

              The header will contain only the list's address for subscribed lists, and both  the
              list  address  and  your  own  email  address for unsubscribed lists.  Without this
              header, a group reply to your message sent to a subscribed list  will  be  sent  to
              both the list and your address, resulting in two copies of the same email for you.

       followup_to_poster
              Type: quadoption
              Default: ask-yes

              If  this variable is set and the keyword "poster" is present in Followup-To header,
              follow-up to newsgroup function is not permitted.  The message will  be  mailed  to
              the submitter of the message via mail.

       force_name
              Type: boolean
              Default: no

              This  variable  is  similar to $save_name, except that NeoMutt will store a copy of
              your outgoing message by the username of the address you are  sending  to  even  if
              that mailbox does not exist.

              Also see the $record variable.

       forward_attachments
              Type: quadoption
              Default: ask-yes

              When  forwarding  inline  (i.e.  $mime_forward  unset  or  answered  with  "no" and
              $forward_decode set), attachments which cannot be decoded in  a  reasonable  manner
              will  be  attached  to  the  newly  composed  message  if this quadoption is set or
              answered with "yes".

       forward_attribution_intro
              Type: string
              Default: "----- Forwarded message from %f -----"

              This is the string that will precede a message which has been forwarded in the main
              body  of  a  message  (when $mime_forward is unset).  For a full listing of defined
              printf(3)-like  sequences   see   the   section   on   $index_format.    See   also
              $attribution_locale.

       forward_attribution_trailer
              Type: string
              Default: "----- End forwarded message -----"

              This  is the string that will follow a message which has been forwarded in the main
              body of a message (when $mime_forward is unset).  For a  full  listing  of  defined
              printf(3)-like   sequences   see   the   section   on   $index_format.    See  also
              $attribution_locale.

       forward_decode
              Type: boolean
              Default: yes

              Controls the decoding of complex MIME messages into text/plain  when  forwarding  a
              message.   The message header is also RFC2047 decoded.  This variable is only used,
              if $mime_forward is unset, otherwise $mime_forward_decode is used instead.

       forward_decrypt
              Type: boolean
              Default: yes

              Controls the handling of encrypted messages when forwarding a message.   When  set,
              the  outer  layer  of  encryption  is  stripped off.  This variable is only used if
              $mime_forward is set and $mime_forward_decode is unset.

       forward_edit
              Type: quadoption
              Default: yes

              This quadoption controls whether or not the user is  automatically  placed  in  the
              editor  when  forwarding  messages.   For  those who always want to forward with no
              modification, use a setting of "no".

       forward_format
              Type: string
              Default: "[%a: %s]"

              This variable controls the default subject when forwarding a message.  It uses  the
              same format sequences as the $index_format variable.

       forward_quote
              Type: boolean
              Default: no

              When  set,  forwarded  messages  included  in  the  main  body of the message (when
              $mime_forward is unset) will be quoted using $indent_string.

       forward_references
              Type: boolean
              Default: no

              When set, forwarded messages set the "In-Reply-To:" and  "References:"  headers  in
              the  same  way as normal replies would. Hence the forwarded message becomes part of
              the original thread instead of starting a new one.

       from
              Type: e-mail address
              Default: ""

              When set, this variable contains a default "from" address.  It  can  be  overridden
              using  "my_hdr" (including from a "send-hook") and $reverse_name.  This variable is
              ignored if $use_from is unset.

              If not specified, then it may be read from the environment variable $EMAIL.

       from_chars
              Type: character string
              Default: ""

              Controls the character used to prefix the %F and %L fields in the index.
              Character
                     Description
              1      Mail is written by you and has a To address, or has a known mailing list  in
                     the To address.
              2      Mail  is written by you and has a Cc address, or has a known mailing list in
                     the Cc address.
              3      Mail is written by you and has a Bcc address.
              4      All remaining cases.

              If this is empty or unset (default), the traditional long "To ", "Cc " and  "Bcc  "
              prefixes  are  used.   If set but too short to include a character for a particular
              case, a single space will be prepended to the field.  To prevent any prefix at  all
              from  being  added  in a particular case, use the special value CR (aka ^M) for the
              corresponding character.

              This slightly odd  interface  is  necessitated  by  NeoMutt's  handling  of  string
              variables;  one  can't  tell  a  variable that is unset from one that is set to the
              empty string.

       gecos_mask
              Type: regular expression
              Default: "^[^,]*"

              A regular expression used by NeoMutt to parse the GECOS field of a  password  entry
              when expanding the alias.  The default value will return the string up to the first
              "," encountered.  If the GECOS field contains a string like  "lastname,  firstname"
              then you should set it to ".*".

              This can be useful if you see the following behavior: you address an e-mail to user
              ID "stevef" whose full name is "Steve Franklin".  If NeoMutt  expands  "stevef"  to
              '"Franklin"  stevef@foo.bar'  then  you  should  set  the  $gecos_mask to a regular
              expression that will match the whole name so  NeoMutt  will  expand  "Franklin"  to
              "Franklin, Steve".

       greeting
              Type: string
              Default: ""

              When  set,  this is the string that will precede every message as a greeting phrase
              to the recipients.

              "Format strings" are similar to the strings used in  the  "C"  function  printf  to
              format  output  (see  the  man  page for more detail).  The following sequences are
              defined in NeoMutt:

              %n     Recipient's real name
              %u     User (login) name of recipient
              %v     First name of recipient

       group_index_format
              Type: string
              Default: "%4C %M%N %5s  %-45.45f %d"

              This variable allows you  to  customize  the  newsgroup  browser  display  to  your
              personal  taste.   This string is similar to "index_format", but has its own set of
              printf()-like sequences:
              %C     Current newsgroup number
              %d     Description of newsgroup (becomes from server)
              %f     Newsgroup name
              %M     - if newsgroup not allowed for direct post (moderated for example)
              %N     N if newsgroup is new, u if unsubscribed, blank otherwise
              %n     Number of new articles in newsgroup
              %s     Number of unread articles in newsgroup
              %>X    Right justify the rest of the string and pad with character "X"
              %|X    Pad to the end of the line with character "X"

       hdrs
              Type: boolean
              Default: yes

              When unset, the header fields normally  added  by  the  "my_hdr"  command  are  not
              created.  This variable must be unset before composing a new message or replying in
              order to take effect.  If set, the user defined header fields are  added  to  every
              new message.

       header
              Type: boolean
              Default: no

              When set, this variable causes NeoMutt to include the header of the message you are
              replying to into the edit buffer.  The $weed setting applies.

       header_cache
              Type: path
              Default: ""

              This variable points to the header  cache  database.  If  the  path  points  to  an
              existing  directory,  NeoMutt  will  create  a  dedicated header cache database per
              folder. Otherwise, the path points to a regular file,  which  will  be  created  as
              needed  and used as a shared global header cache for all folders.  By default it is
              unset so no header caching will be used.

              Header caching can greatly improve speed when  opening  POP,  IMAP  MH  or  Maildir
              folders, see "caching" in the NeoMutt Guide for details.

       header_cache_backend
              Type: string
              Default: ""

              This  variable specifies the header cache backend.  If no backend is specified, the
              first available  backend  will  be  used  in  the  following  order:  tokyocabinet,
              kyotocabinet, qdbm, rocksdb, gdbm, bdb, tdb, lmdb.

       header_cache_compress_level
              Type: number
              Default: 1

              When  NeoMutt  is compiled with lz4, zstd or zlib, this option can be used to setup
              the compression level.

       header_cache_compress_method
              Type: string
              Default: ""

              When NeoMutt is compiled with lz4, zstd or zlib, the header cache backend  can  use
              these  compression  methods  for compressing the cache files.  This results in much
              smaller cache file sizes and may even improve speed.

       header_color_partial
              Type: boolean
              Default: no

              When set, color header regexes behave like color body regexes: color is applied  to
              the  exact  text  matched by the regex.  When unset, color is applied to the entire
              header.

              One use of this option might be to apply color to just the header labels.

              See "color" for more details.

       help
              Type: boolean
              Default: yes

              When set, help lines describing the bindings for the major  functions  provided  by
              each menu are displayed on the first line of the screen.

              Note:  The  binding  will  not be displayed correctly if the function is bound to a
              sequence rather than a single keystroke.  Also, the help line may not be updated if
              a  binding  is  changed while NeoMutt is running.  Since this variable is primarily
              aimed at new users, neither of these should present a major problem.

       hidden_host
              Type: boolean
              Default: no

              When set, NeoMutt will skip the host name part of $hostname  variable  when  adding
              the domain part to addresses.

       hidden_tags
              Type: string list
              Default: "unread,draft,flagged,passed,replied,attachment,signed,encrypted"

              This  variable  specifies a list of comma-separated private notmuch/imap tags which
              should not be printed on screen.

       hide_limited
              Type: boolean
              Default: no

              When set, NeoMutt will not show  the  presence  of  messages  that  are  hidden  by
              limiting, in the thread tree.

       hide_missing
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  not  show the presence of missing messages in the thread
              tree.

       hide_thread_subject
              Type: boolean
              Default: yes

              When set, NeoMutt will not show the subject of messages in  the  thread  tree  that
              have the same subject as their parent or closest previously displayed sibling.

       hide_top_limited
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  not  show  the  presence  of messages that are hidden by
              limiting, at the top of threads in the thread tree.  Note that  when  $hide_limited
              is set, this option will have no effect.

       hide_top_missing
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  not  show the presence of missing messages at the top of
              threads in the thread tree.  Note that when $hide_missing is set, this option  will
              have no effect.

       history
              Type: number
              Default: 10

              This  variable  controls  the  size (in number of strings remembered) of the string
              history buffer per category. The buffer is cleared each time the variable is set.

              Note that strings (e.g. commands) starting with a space are never recorded  in  the
              history.   This is for example useful to prevent leaking sensitive information into
              the history file or for one off tests.

              Also note that a string is not added to the  history  if  it  exactly  matches  its
              immediate  predecessor,  e.g.  executing the same command twice in a row results in
              only one copy being added to the history.  To prevent duplicates over  all  entries
              use $history_remove_dups.

       history_file
              Type: path
              Default: "~/.mutthistory"

              The file in which NeoMutt will save its history.

              Also see $save_history.

       history_remove_dups
              Type: boolean
              Default: no

              When set, all of the string history will be scanned for duplicates when a new entry
              is added.  Duplicate entries in the $history_file will also be removed when  it  is
              periodically compacted.

       honor_disposition
              Type: boolean
              Default: no

              When  set,  NeoMutt will not display attachments with a disposition of "attachment"
              inline even if it could render the part to plain text. These MIME parts can only be
              viewed from the attachment menu.

              If  unset,  NeoMutt  will  render all MIME parts it can properly transform to plain
              text.

       honor_followup_to
              Type: quadoption
              Default: yes

              This variable controls whether or not a Mail-Followup-To  header  is  honored  when
              group-replying to a message.

       hostname
              Type: string
              Default: ""

              Specifies  the  fully-qualified  hostname  of  the  system  NeoMutt  is  running on
              containing the host's name and the DNS domain it belongs to.  It  is  used  as  the
              domain part (after "@") for local email addresses.

              If  not specified in a config file, then NeoMutt will try to determine the hostname
              itself.

              Optionally, NeoMutt can be compiled with a fixed domain name.

              Also see $use_domain and $hidden_host.

              Note:  On  Debian  systems,  the  default  for  this  variable  is  obtained   from
              /etc/mailname when Mutt starts.

       idn_decode
              Type: boolean
              Default: yes

              When  set, NeoMutt will show you international domain names decoded.  Note: You can
              use IDNs for addresses even if this is unset.  This variable only affects decoding.
              (IDN only)

       idn_encode
              Type: boolean
              Default: yes

              When  set, NeoMutt will encode international domain names using IDN.  Unset this if
              your SMTP server can handle newer (RFC6531) UTF-8 encoded domains. (IDN only)

       ignore_list_reply_to
              Type: boolean
              Default: no

              Affects the behavior of the <reply> function when replying to messages from mailing
              lists  (as  defined  by  the  "subscribe"  or  "lists" commands).  When set, if the
              "Reply-To:" field is set to the same value as the "To:" field, NeoMutt assumes that
              the  "Reply-To:"  field  was  set  by the mailing list to automate responses to the
              list, and will ignore this field.  To direct a response to the  mailing  list  when
              this option is set, use the <list-reply> function; <group-reply> will reply to both
              the sender and the list.

       imap_authenticators
              Type: string list
              Default: ""

              This is a colon-separated list of authentication methods NeoMutt may attempt to use
              to  log in to an IMAP server, in the order NeoMutt should try them.  Authentication
              methods are either "login" or the right  side  of  an  IMAP  "AUTH=xxx"  capability
              string, e.g. "digest-md5", "gssapi" or "cram-md5". This option is case-insensitive.
              If it's unset (the default) NeoMutt will try all available methods, in  order  from
              most-secure to least-secure.

              Example:

              set imap_authenticators="gssapi:cram-md5:login"

              Note:  NeoMutt  will only fall back to other authentication methods if the previous
              methods are unavailable. If a method is available but authentication fails, NeoMutt
              will not connect to the IMAP server.

       imap_check_subscribed
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  fetch  the  set  of  subscribed folders from your server
              whenever a mailbox is selected, and add them to the set of mailboxes it  polls  for
              new mail just as if you had issued individual "mailboxes" commands.

       imap_condstore
              Type: boolean
              Default: no

              When  set,  NeoMutt will use the CONDSTORE extension (RFC7162) if advertised by the
              server.  NeoMutt's current implementation is basic, used only for  initial  message
              fetching and flag updates.

              For  some  IMAP  servers,  enabling this will slightly speed up downloading initial
              messages.  Unfortunately, Gmail is not one those, and  displays  worse  performance
              when enabled.  Your mileage may vary.

       imap_deflate
              Type: boolean
              Default: yes

              When  set,  NeoMutt will use the COMPRESS=DEFLATE extension (RFC4978) if advertised
              by the server.

              In general a good compression efficiency can be achieved, which speeds  up  reading
              large mailboxes also on fairly good connections.

       imap_delim_chars
              Type: string
              Default: "/."

              This contains the list of characters that NeoMutt will use as folder separators for
              IMAP paths, when no separator is provided on the IMAP connection.

       imap_fetch_chunk_size
              Type: number (long)
              Default: 0

              When set to a value greater than 0, new headers will be  downloaded  in  groups  of
              this  many  headers  per  request.   If  you  have a very large mailbox, this might
              prevent a timeout and disconnect when opening the mailbox, by sending a  FETCH  per
              set of this many headers, instead of a single FETCH for all new headers.

       imap_headers
              Type: string
              Default: ""

              NeoMutt  requests  these header fields in addition to the default headers ("Date:",
              "From:",  "Sender:",  "Subject:",  "To:",  "Cc:",   "Message-Id:",   "References:",
              "Content-Type:",  "Content-Description:",  "In-Reply-To:",  "Reply-To:",  "Lines:",
              "List-Post:", "X-Label:") from IMAP servers before displaying the index  menu.  You
              may want to add more headers for spam detection.

              Note: This is a space separated list, items should be uppercase and not contain the
              colon, e.g. "X-BOGOSITY X-SPAM-STATUS" for the "X-Bogosity:"  and  "X-Spam-Status:"
              header fields.

       imap_idle
              Type: boolean
              Default: no

              When set, NeoMutt will attempt to use the IMAP IDLE extension to check for new mail
              in the current mailbox. Some servers (dovecot was the inspiration for this  option)
              react  badly  to  NeoMutt's  implementation.  If your connection seems to freeze up
              periodically, try unsetting this.

       imap_keep_alive
              Type: number
              Default: 300

              This variable specifies the maximum amount of time in  seconds  that  NeoMutt  will
              wait  before polling open IMAP connections, to prevent the server from closing them
              before NeoMutt has finished with them. The default is well within the RFC-specified
              minimum  amount  of time (30 minutes) before a server is allowed to do this, but in
              practice the RFC does get violated every now and then. Reduce this  number  if  you
              find yourself getting disconnected from your IMAP server due to inactivity.

       imap_list_subscribed
              Type: boolean
              Default: no

              This variable configures whether IMAP folder browsing will look for only subscribed
              folders or all folders.   This  can  be  toggled  in  the  IMAP  browser  with  the
              <toggle-subscribed> function.

       imap_login
              Type: string
              Default: ""

              Your login name on the IMAP server.

              This variable defaults to the value of $imap_user.

       imap_oauth_refresh_command
              Type: command
              Default: ""

              The  command  to  run  to  generate  an  OAUTH  refresh  token for authorizing your
              connection to your IMAP server.  This command  will  be  run  on  every  connection
              attempt  that  uses  the  OAUTHBEARER  or  XOAUTH2  authentication mechanisms.  See
              "oauth" for details.

       imap_pass
              Type: string
              Default: ""

              Specifies the password for your IMAP account.  If unset, NeoMutt  will  prompt  you
              for  your password when you invoke the <imap-fetch-mail> function or try to open an
              IMAP folder.

              Warning: you should only use this option when you are on a fairly  secure  machine,
              because  the superuser can read your neomuttrc even if you are the only one who can
              read the file.

       imap_passive
              Type: boolean
              Default: yes

              When set, NeoMutt will not open  new  IMAP  connections  to  check  for  new  mail.
              NeoMutt  will  only  check  for  new  mail over existing IMAP connections.  This is
              useful if you don't  want  to  be  prompted  for  user/password  pairs  on  NeoMutt
              invocation, or if opening the connection is slow.

       imap_peek
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  avoid  implicitly marking your mail as read whenever you
              fetch a message from the server. This is generally  a  good  thing,  but  can  make
              closing an IMAP folder somewhat slower. This option exists to appease speed freaks.

       imap_pipeline_depth
              Type: number
              Default: 15

              Controls  the number of IMAP commands that may be queued up before they are sent to
              the server. A deeper pipeline reduces the amount of time NeoMutt must wait for  the
              server,  and  can  make IMAP servers feel much more responsive. But not all servers
              correctly handle pipelined commands, so if you have problems you might want to  try
              setting this variable to 0.

              Note: Changes to this variable have no effect on open connections.

       imap_poll_timeout
              Type: number
              Default: 15

              This  variable  specifies  the  maximum amount of time in seconds that NeoMutt will
              wait for a response when polling IMAP connections for new mail, before  timing  out
              and closing the connection.  Set to 0 to disable timing out.

       imap_qresync
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  use the QRESYNC extension (RFC7162) if advertised by the
              server.  NeoMutt's current implementation is basic, used only for  initial  message
              fetching and flag updates.

              Note:  this feature is currently experimental.  If you experience strange behavior,
              such as duplicate or missing messages please file a bug report to let us know.

       imap_rfc5161
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  use  the  IMAP  ENABLE  extension  (RFC5161)  to  select
              CAPABILITIES.  Some  servers  (notably Coremail System IMap Server) do not properly
              respond to ENABLE commands, which might cause NeoMutt to hang.  If your  connection
              seems     to     freeze    at    login,    try    unsetting    this.    See    also
              https://github.com/neomutt/neomutt/issues/1689

       imap_server_noise
              Type: boolean
              Default: yes

              When set, NeoMutt will display warning messages  from  the  IMAP  server  as  error
              messages.   Since   these   messages  are  often  harmless,  or  generated  due  to
              configuration problems on the server which are out of the  users'  hands,  you  may
              wish to suppress them at some point.

       imap_user
              Type: string
              Default: ""

              The name of the user whose mail you intend to access on the IMAP server.

              This variable defaults to your user name on the local machine.

       imap_send_id
              Type: boolean
              Default: no

              When set, NeoMutt will send an IMAP ID command (RFC2971) to the server when logging
              in if advertised by the server. This command provides information  about  the  IMAP
              client, such as "NeoMutt" and the current version.

       implicit_auto_view
              Type: boolean
              Default: no

              If  set  to  "yes",  NeoMutt will look for a mailcap entry with the "copiousoutput"
              flag set for every MIME attachment it doesn't have an internal viewer defined  for.
              If  such  an  entry  is found, NeoMutt will use the viewer defined in that entry to
              convert the body part to text form.

       include
              Type: quadoption
              Default: ask-yes

              Controls whether or not a copy of the message(s) you are replying to is included in
              your reply.

       include_encrypted
              Type: boolean
              Default: no

              Controls  whether  or not NeoMutt includes separately encrypted attachment contents
              when replying.

              This variable was added to prevent accidental exposure of encrypted  contents  when
              replying  to  an  attacker.  If a previously encrypted message were attached by the
              attacker, they could trick an unwary recipient into decrypting  and  including  the
              message in their reply.

       include_only_first
              Type: boolean
              Default: no

              Controls  whether  or not NeoMutt includes only the first attachment of the message
              you are replying.

       indent_string
              Type: string
              Default: "> "

              Specifies the string to prepend to each line of text quoted in a message  to  which
              you  are  replying.   You  are  strongly encouraged not to change this value, as it
              tends to agitate the more fanatical netizens.

              The value of this option is ignored if $text_flowed is  set,  because  the  quoting
              mechanism is strictly defined for format=flowed.

              This  option  is  a  format string, please see the description of $index_format for
              supported printf(3)-style sequences.

       index_format
              Type: string
              Default: "%4C %Z %{%b %d} %-15.15L (%<l?%4l&%4c>) %s"

              This variable allows you to customize the message index display  to  your  personal
              taste.

              "Format  strings"  are  similar  to the strings used in the C function printf(3) to
              format output (see the man page for more  details).   For  an  explanation  of  the
              %<...>  construct,  see the status_format description.  The following sequences are
              defined in NeoMutt:
              %a     Address of the author
              %A     Reply-to address (if present; otherwise: address of author)
              %b     Filename of the original message folder (think mailbox)
              %B     Same as %K
              %C     Current message number
              %c     Number of characters (bytes) in the body of the message (see  formatstrings-

              %cr    Number  of  characters (bytes) in the raw message, including the header (see
                     formatstrings-size)
              %D     Date and time  of  message  using  date_format  and  local  timezone  It  is
                     encouraged   to   use   "%[fmt]"  instead,  where  "fmt"  is  the  value  of
                     $date_format.
              %d     Date and time of message using  date_format  and  sender's  timezone  It  is
                     encouraged   to   use   "%{fmt}"  instead,  where  "fmt"  is  the  value  of
                     $date_format.
              %e     Current message number in thread
              %E     Number of messages in current thread
              %F     Author name, or recipient name if the message is from you
              %Fp    Like %F, but plain. No contextual formatting is applied to recipient name

              %g     Newsgroup name (if compiled with NNTP support)
              %g     Message tags (e.g. notmuch tags/imap flags)
              %Gx    Individual message tag (e.g. notmuch tags/imap flags)
              %H     Spam attribute(s) of this message
              %I     Initials of author
              %i     Message-id of the current message
              %J     Message tags (if present, tree unfolded, and != parent's tags)
              %K     The list to which the letter was sent (if any; otherwise: empty)
              %L     If an address in the "To:" or "Cc:" header field matches an address  Defined
                     by the user's "subscribe" command, this displays "To <list-name>", otherwise
                     the same as %F
              %l     number of lines in the unprocessed message (may not work with  maildir,  mh,
                     and IMAP folders)
              %M     Number of hidden messages if the thread is collapsed

              %N     Message score
              %n     Author's real name (or address if missing)
              %O     Original  save folder where NeoMutt would formerly have Stashed the message:
                     list name or recipient name If not sent to a list
              %P     Progress indicator for the built-in pager (how much of  the  file  has  been
                     displayed)
              %q     Newsgroup name (if compiled with NNTP support)
              %R     Comma separated list of "Cc:" recipients
              %r     Comma separated list of "To:" recipients
              %S     Single character status of the message ("N"/"O"/"D"/"d"/"!"/"r"/"*")
              %s     Subject of the message

              %v     First name of the author, or the recipient if the message is from you
              %W     Name of organization of author ("Organization:" field)
              %x     "X-Comment-To:" field (if present and compiled with NNTP support)
              %X     Number  of  MIME  attachments  (please  see  the  "attachments"  section for
                     possible speed effects)
              %Y     "X-Label:" field, if present, and (1) not at part of a thread tree,  (2)  at
                     the top of a thread, or (3) "X-Label:" is different from Preceding message's
                     "X-Label:"
              %y     "X-Label:" field, if present
              %Z     A three character set of message  status  flags.   The  first  character  is
                     new/read/replied  flags  ("n"/"o"/"r"/"O"/"N").   The  second  is deleted or
                     encryption   flags   ("D"/"d"/"S"/"P"/"s"/"K").    The   third   is   either
                     tagged/flagged ("*"/"!"), or one of the characters Listed in $to_chars.
              %zc    Message crypto flags

                     insert  and  evaluate  format-string  from  the matching "index-format-hook"
                     command
              %{fmt} the date and time of the message is converted to  sender's  time  zone,  and
                     "fmt"  is  expanded  by  the  library  function  strftime(3);  if  the first
                     character inside the braces is a bang ("!"), the date is formatted  ignoring
                     any  locale  settings.   Note  that  the  sender's  time  zone might only be
                     available as a numerical offset, so "%Z" behaves like "%z".
              %[fmt] the date and time of the message is converted to the local  time  zone,  and
                     "fmt"  is  expanded  by  the  library  function  strftime(3);  if  the first
                     character inside the brackets  is  a  bang  ("!"),  the  date  is  formatted
                     ignoring any locale settings.
              %(fmt) the local date and time when the message was received, and "fmt" is expanded
                     by the library function strftime(3);  if  the  first  character  inside  the
                     parentheses  is  a  bang  ("!"),  the  date is formatted ignoring any locale
                     settings.
              %>X    right justify the rest of the string and pad with character "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

              Date format expressions can be constructed based on relative dates. Using the  date
              formatting  operators  along  with  nested  conditionals,  the  date  format can be
              modified based on how old a message is.  See the section on "Conditional Dates" for
              an explanation and examples

              Note  that  for  mbox/mmdf,  "%l"  applies  to  the  unprocessed  message,  and for
              maildir/mh, the value comes from  the  "Lines:"  header  field  when  present  (the
              meaning  is normally the same). Thus the value depends on the encodings used in the
              different parts of the message and has little meaning in practice.

              "Soft-fill"  deserves  some  explanation:  Normal  right-justification  will  print
              everything  to  the  left  of the "%>", displaying padding and whatever lies to the
              right only if there's room. By contrast, soft-fill gives priority to the right-hand
              side,  guaranteeing  space  to display it and showing padding only if there's still
              room. If necessary, soft-fill will eat text leftwards to make  room  for  rightward
              text.

              Note  that  these  expandos are supported in "save-hook", "fcc-hook" and "fcc-save-
              hook", too.

       inews
              Type: command
              Default: ""

              If set, specifies the program and arguments used to deliver news posted by NeoMutt.
              Otherwise,  NeoMutt  posts  article  using  current connection to news server.  The
              following printf-style sequence is understood:
              %a     account url
              %p     port
              %P     port if specified
              %s     news server name
              %S     url schema
              %u     username

              Example:

              set inews="/usr/local/bin/inews -hS"

       ispell
              Type: command
              Default: "ispell"

              How to invoke ispell (GNU's spell-checking software).

       keep_flagged
              Type: boolean
              Default: no

              If set, read messages marked as flagged will not be moved from your  spool  mailbox
              to your $mbox mailbox or to the "mbox" specified by a mbox-hook command.

              Note that $keep_flagged only has an effect if $move is set.

       local_date_header
              Type: boolean
              Default: yes

              If  set,  the date in the Date header of emails that you send will be in your local
              timezone. If unset a UTC date will be used instead  to  avoid  leaking  information
              about your current location.

       mail_check
              Type: number
              Default: 5

              This  variable  configures how often (in seconds) NeoMutt should look for new mail.
              Also see the $timeout variable.

       mail_check_recent
              Type: boolean
              Default: yes

              When set, NeoMutt will only notify you about new mail that has been received  since
              the  last  time you opened the mailbox.  When unset, NeoMutt will notify you if any
              new mail exists in the mailbox, regardless of whether you have visited it recently.

              When $mark_old is set, NeoMutt does not consider the mailbox to contain new mail if
              only old messages exist.

       mail_check_stats
              Type: boolean
              Default: no

              When set, NeoMutt will periodically calculate message statistics of a mailbox while
              polling for new mail.  It will check for unread, flagged, and total message counts.
              Because this operation is more performance intensive, it defaults to unset, and has
              a separate option, $mail_check_stats_interval, to control how often to update these
              counts.

              Message  statistics can also be explicitly calculated by invoking the <check-stats>
              function.

       mail_check_stats_interval
              Type: number
              Default: 60

              When $mail_check_stats is set, this variable  configures  how  often  (in  seconds)
              NeoMutt will update message counts.

       mailbox_folder_format
              Type: string
              Default: "%2C %<n?%6n&      > %6m %i"

              This  variable  allows  you  to customize the file browser display to your personal
              taste. It's only used to customize network mailboxes (e.g. imap).  This  string  is
              identical in formatting to the one used by "$folder_format".

       mailcap_path
              Type: string list
              Default: "~/.mailcap:/usr/share/neomutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/etc/mailcap:/usr/local/etc/mailcap"

              This  variable specifies a list of colon-separated files to consult when attempting
              to display MIME bodies not directly supported by NeoMutt.   The  default  value  is
              generated during startup: see the "mailcap" section of the manual.

              $mailcap_path is overridden by the environment variable $MAILCAPS.

              The default search path is from RFC1524.

       mailcap_sanitize
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will  restrict  possible  characters  in mailcap % expandos to a
              well-defined set of safe characters.  This is the safe setting, but we are not sure
              it doesn't break some more advanced MIME stuff.

              DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY SURE WHAT YOU ARE DOING!

       maildir_check_cur
              Type: boolean
              Default: no

              If  set, NeoMutt will poll both the new and cur directories of a maildir folder for
              new messages.  This might be useful if other programs interacting with  the  folder
              (e.g.  dovecot)  are  moving  new messages to the cur directory.  Note that setting
              this option may slow down polling for new messages in large folders, since  NeoMutt
              has to scan all cur messages.

       maildir_field_delimiter
              Type: string
              Default: ":"

              Use  the  value  as  maildir  field  delimiter.  This is a single-character used to
              accommodate maildir mailboxes on platforms where `:` is not allowed in a  filename.
              The  recommended  alternative  on  such  platforms  is  `;`.   Neomutt supports all
              non-alphanumeric values except for `-`, `.`, `\`, `/`.  Note: this only applies  to
              maildir-style mailboxes. Setting it will have no effect on other mailbox types.

       maildir_header_cache_verify
              Type: boolean
              Default: yes

              Check for Maildir unaware programs other than NeoMutt having modified maildir files
              when the header cache is in use.  This incurs one stat(2) per  message  every  time
              the folder is opened (which can be very slow for NFS folders).

       maildir_trash
              Type: boolean
              Default: no

              If  set,  messages  marked  as  deleted will be saved with the maildir trashed flag
              instead of unlinked.  Note: this only applies to maildir-style mailboxes.   Setting
              it will have no effect on other mailbox types.

       mark_macro_prefix
              Type: string
              Default: "'"

              Prefix  for macros created using mark-message.  A new macro automatically generated
              with <mark-message>a will be composed from this prefix and the letter a.

       mark_old
              Type: boolean
              Default: yes

              Controls whether or not NeoMutt marks new unread messages as  old  if  you  exit  a
              mailbox  without  reading  them.   With  this  option  set, the next time you start
              NeoMutt, the messages will show up with an "O" next to  them  in  the  index  menu,
              indicating that they are old.

       markers
              Type: boolean
              Default: yes

              Controls  the  display of wrapped lines in the internal pager. If set, a "+" marker
              is displayed at the beginning of wrapped lines.

              Also see the $smart_wrap variable.

       mask
              Type: regular expression
              Default: "!^\.[^.]"

              A regular expression used in the file  browser,  optionally  preceded  by  the  not
              operator  "!".   Only files whose names match this mask will be shown. The match is
              always case-sensitive.

       mbox
              Type: mailbox
              Default: "~/mbox"

              This specifies the folder into which read mail in your $spool_file folder  will  be
              appended.

              Also see the $move variable.

       mbox_type
              Type: enumeration
              Default: mbox

              The  default  mailbox  type  used  when creating new folders. May be any of "mbox",
              "MMDF", "MH" or "Maildir".

              This can also be set using the -m command-line option.

       me_too
              Type: boolean
              Default: no

              If unset, NeoMutt will remove your address (see the "alternates" command) from  the
              list of recipients when replying to a message.

       menu_context
              Type: number
              Default: 0

              This variable controls the number of lines of context that are given when scrolling
              through menus. (Similar to $pager_context.)

       menu_move_off
              Type: boolean
              Default: yes

              When unset, the bottom entry of menus will never scroll up past the bottom  of  the
              screen,  unless  there are less entries than lines.  When set, the bottom entry may
              move off the bottom.

       menu_scroll
              Type: boolean
              Default: no

              When set, menus will be scrolled up or down one  line  when  you  attempt  to  move
              across a screen boundary.  If unset, the screen is cleared and the next or previous
              page of the menu is displayed (useful for slow links to avoid many redraws).

       message_cache_clean
              Type: boolean
              Default: no

              If set, NeoMutt will clean out obsolete entries from the  message  cache  when  the
              mailbox  is  synchronized.  You probably only want to set it every once in a while,
              since it can be a little slow (especially for large folders).

       message_cache_dir
              Type: path
              Default: ""

              Set this to a directory and NeoMutt will cache copies of messages  from  your  IMAP
              and POP servers here. You are free to remove entries at any time.

              When  setting  this  variable  to  a directory, NeoMutt needs to fetch every remote
              message only once and can perform regular expression searches as fast as for  local
              folders.

              Also see the $message_cache_clean variable.

       message_format
              Type: string
              Default: "%s"

              This  is  the  string  displayed  in  the "attachment" menu for attachments of type
              message/rfc822.  For a full listing of defined  printf(3)-like  sequences  see  the
              section on $index_format.

       meta_key
              Type: boolean
              Default: no

              If  set, forces NeoMutt to interpret keystrokes with the high bit (bit 8) set as if
              the user had pressed the Esc key and whatever key remains after having the high bit
              removed.   For example, if the key pressed has an ASCII value of 0xf8, then this is
              treated as if the user had pressed Esc then "x".  This is  because  the  result  of
              removing the high bit from 0xf8 is 0x78, which is the ASCII character "x".

       mh_purge
              Type: boolean
              Default: no

              When  unset,  NeoMutt will mimic mh's behavior and rename deleted messages to ,<old
              file name> in mh folders instead of really deleting them. This leaves  the  message
              on  disk  but  makes programs reading the folder ignore it. If the variable is set,
              the message files will simply be deleted.

              This option is similar to $maildir_trash for Maildir folders.

       mh_seq_flagged
              Type: string
              Default: "flagged"

              The name of the MH sequence used for flagged messages.

       mh_seq_replied
              Type: string
              Default: "replied"

              The name of the MH sequence used to tag replied messages.

       mh_seq_unseen
              Type: string
              Default: "unseen"

              The name of the MH sequence used for unseen messages.

       mime_forward
              Type: quadoption
              Default: no

              When  set,  the  message  you  are  forwarding  will  be  attached  as  a  separate
              message/rfc822 MIME part instead of included in the main body of the message.  This
              is useful for forwarding MIME messages  so  the  receiver  can  properly  view  the
              message as it was delivered to you. If you like to switch between MIME and not MIME
              from mail to mail, set this variable to "ask-no" or "ask-yes".

              Also see $forward_decode and $mime_forward_decode.

       mime_forward_decode
              Type: boolean
              Default: no

              Controls the decoding of complex MIME messages into text/plain  when  forwarding  a
              message while $mime_forward is set. Otherwise $forward_decode is used instead.

       mime_forward_rest
              Type: quadoption
              Default: yes

              When  forwarding  multiple  attachments of a MIME message from the attachment menu,
              attachments which can't be decoded in a reasonable manner will be attached  to  the
              newly composed message if this option is set.

       mime_type_query_command
              Type: command
              Default: ""

              This  specifies  a  command  to run, to determine the mime type of a new attachment
              when composing a message.  Unless $mime_type_query_first is set, this will only  be
              run if the attachment's extension is not found in the mime.types file.

              The  string  may  contain  a  "%s",  which  will be substituted with the attachment
              filename.   NeoMutt  will  add  quotes  around  the  string  substituted  for  "%s"
              automatically  according  to  shell  quoting rules, so you should avoid adding your
              own.  If no "%s" is found  in  the  string,  NeoMutt  will  append  the  attachment
              filename to the end of the string.

              The command should output a single line containing the attachment's mime type.

              Suggested values are "xdg-mime query filetype" or "file -bi".

       mime_type_query_first
              Type: boolean
              Default: no

              When set, the $mime_type_query_command will be run before the mime.types lookup.

       mix_entry_format
              Type: string
              Default: "%4n %c %-16s %a"

              This  variable  describes  the  format  of  a  remailer line on the mixmaster chain
              selection screen.  The following printf(3)-like sequences are supported:
              %a     The remailer's e-mail address
              %c     Remailer capabilities
              %n     The running number on the menu
              %s     The remailer's short name
              %>X    right justify the rest of the string and pad with character "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

       mixmaster
              Type: command
              Default: "mixmaster"

              This variable contains the path to the Mixmaster binary on your system.  It is used
              with  various  sets  of  parameters  to  gather the list of known remailers, and to
              finally send a message through the mixmaster chain.

              Note: On Debian systems, this option is set by  default  to  “mixmaster-filter”  in
              /etc/Muttrc.

       move
              Type: quadoption
              Default: no

              If  this  variable  is  set,  then  NeoMutt will move read messages from your spool
              mailbox to your $mbox mailbox or to the "mbox" specified by a mbox-hook command.

              See also $keep_flagged.

       narrow_tree
              Type: boolean
              Default: no

              This variable, when set, makes the thread tree narrower, allowing deeper threads to
              fit on the screen.

       net_inc
              Type: number
              Default: 10

              Operations  that  expect  to  transfer a large amount of data over the network will
              update their progress every $net_inc kilobytes.  If set to 0, no progress  messages
              will be displayed.

              See also $read_inc, $write_inc and $net_inc.

       new_mail_command
              Type: command
              Default: ""

              If  set,  NeoMutt  will call this command after a new message is received.  See the
              $status_format documentation for  the  values  that  can  be  formatted  into  this
              command.

       news_cache_dir
              Type: path
              Default: "~/.neomutt"

              This  variable  pointing  to directory where NeoMutt will save cached news articles
              and headers in. If unset, articles and headers will not be saved at all and will be
              reloaded from the server each time.

       news_server
              Type: string
              Default: ""

              This variable specifies domain name or address of NNTP server.

              You  can  also  specify username and an alternative port for each news server, e.g.
              [[s]news://][username[:password]@]server[:port]

              This option can also be set using the command line  option  "-g",  the  environment
              variable $NNTPSERVER, or putting the server name in the file "/etc/nntpserver".

       newsgroups_charset
              Type: string
              Default: "utf-8"

              Character set of newsgroups descriptions.

       newsrc
              Type: path
              Default: "~/.newsrc"

              The  file,  containing info about subscribed newsgroups - names and indexes of read
              articles.  The following printf-style sequence is understood:
              Expando
                     Description Example
              %a     Account url news:news.gmane.org
              %p     Port 119
              %P     Port if specified 10119
              %s     News server name news.gmane.org
              %S     Url schema news
              %u     Username username

       nm_config_file
              Type: path
              Default: "auto"

              Configuration file for notmuch. Use 'auto' to detect configuration.

       nm_config_profile
              Type: string
              Default: ""

              Configuration profile for notmuch.

       nm_db_limit
              Type: number
              Default: 0

              This variable specifies the default limit used in notmuch queries.

       nm_default_url
              Type: string
              Default: ""

              This variable specifies the default Notmuch database in format  notmuch://<absolute
              path>.

       nm_exclude_tags
              Type: string
              Default: ""

              The  messages tagged with these tags are excluded and not loaded from notmuch DB to
              NeoMutt unless specified explicitly.

       nm_flagged_tag
              Type: string
              Default: "flagged"

              This variable specifies notmuch  tag  which  is  used  for  flagged  messages.  The
              variable  is  used  to  count  flagged messages in DB and set the flagged flag when
              modifying tags. All other NeoMutt commands use standard (e.g. maildir) flags.

       nm_open_timeout
              Type: number
              Default: 5

              This variable specifies the timeout for database open in seconds.

       nm_query_type
              Type: string
              Default: "messages"

              This variable specifies the default  query  type  (threads  or  messages)  used  in
              notmuch queries.

       nm_query_window_current_position
              Type: number
              Default: 0

              This variable contains the position of the current search for window based vfolder.

       nm_query_window_current_search
              Type: string
              Default: ""

              This variable contains the currently setup notmuch search for window based vfolder.

       nm_query_window_duration
              Type: number
              Default: 0

              This  variable sets the time duration of a windowed notmuch query.  Accepted values
              all non negative integers. A value of 0 disables the feature.

       nm_query_window_enable
              Type: boolean
              Default: no

              This variable enables windowed notmuch queries even if window duration is 0.

       nm_query_window_or_terms
              Type: string
              Default: ""

              This variable contains additional notmuch search terms for  messages  to  be  shown
              regardless of date.

              Example:

              Using  "notmuch://?query=tag:inbox" as the mailbox and "tag:flagged and tag:unread"
              as the or terms, NeoMutt will produce a query window such as:

              notmuch://?query=tag:inbox and (date:... or (tag:flagged and tag:unread))

       nm_query_window_timebase
              Type: string
              Default: "week"

              This variable sets the time base of a windowed notmuch query.  Accepted values  are
              'minute', 'hour', 'day', 'week', 'month', 'year'

       nm_record
              Type: boolean
              Default: no

              This  variable  specifies whether, when writing a just-sent message to the $record,
              the message should also be added to the notmuch DB.  Replies  inherit  the  notmuch
              tags  from  the  original message. See $nm_record_tags for how to modify the set of
              notmuch tags assigned to sent messages written to the record.

       nm_record_tags
              Type: string
              Default: ""

              This variable specifies the notmuch tag modifications (addition, removal, toggling)
              applied  to  messages  added to the Neomutt record when $nm_record is true. See the
              description of the <modify-labels> function for the syntax.

       nm_replied_tag
              Type: string
              Default: "replied"

              This variable specifies notmuch  tag  which  is  used  for  replied  messages.  The
              variable  is  used  to  set the replied flag when modifying tags. All other NeoMutt
              commands use standard (e.g. maildir) flags.

       nm_unread_tag
              Type: string
              Default: "unread"

              This variable specifies notmuch tag which is used for unread messages. The variable
              is  used  to  count  unread  messages in DB and set the unread flag when modifiying
              tags. All other NeoMutt commands use standard (e.g. maildir) flags.

       nntp_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods NeoMutt may attempt to use
              to  log  in to a news server, in the order NeoMutt should try them.  Authentication
              methods are either "user" or any SASL mechanism,  e.g.  "digest-md5",  "gssapi"  or
              "cram-md5".   This option is case-insensitive.  If it's unset (the default) NeoMutt
              will try all available methods, in order from most-secure to least-secure.

              Example:

              set nntp_authenticators="digest-md5:user"

              Note: NeoMutt will only fall back to other authentication methods if  the  previous
              methods are unavailable. If a method is available but authentication fails, NeoMutt
              will not connect to the IMAP server.

       nntp_context
              Type: number (long)
              Default: 1000

              This variable defines number of articles which will  be  in  index  when  newsgroup
              entered.   If active newsgroup have more articles than this number, oldest articles
              will be ignored.  Also controls how many articles headers will be  saved  in  cache
              when you quit newsgroup.

       nntp_listgroup
              Type: boolean
              Default: yes

              This  variable  controls  whether  or not existence of each article is checked when
              newsgroup is entered.

       nntp_load_description
              Type: boolean
              Default: yes

              This variable controls whether or not  descriptions  for  each  newsgroup  must  be
              loaded  when  newsgroup  is added to list (first time list loading or new newsgroup
              adding).

       nntp_pass
              Type: string
              Default: ""

              Your password for NNTP account.

       nntp_poll
              Type: number
              Default: 60

              The time in seconds until any operations on newsgroup except post new article  will
              cause  recheck  for  new news.  If set to 0, NeoMutt will recheck newsgroup on each
              operation in index (stepping, read article, etc.).

       nntp_user
              Type: string
              Default: ""

              Your  login  name  on  the  NNTP  server.   If  unset  and  NNTP  server   requires
              authentication,  NeoMutt  will prompt you for your account name when you connect to
              news server.

       pager
              Type: command
              Default: "builtin"

              This variable specifies which pager you would like to use  to  view  messages.  The
              value  "builtin"  means  to  use the built-in pager, otherwise this variable should
              specify the pathname of the external pager you would like to use.

              Using an external pager may have  some  disadvantages:  Additional  keystrokes  are
              necessary  because  you  can't  call NeoMutt functions directly from the pager, and
              screen resizes cause lines longer than the screen width to be  badly  formatted  in
              the help menu.

       pager_context
              Type: number
              Default: 0

              This  variable  controls  the  number  of  lines  of  context  that  are given when
              displaying the next or previous page in the internal pager.   By  default,  NeoMutt
              will  display the line after the last one on the screen at the top of the next page
              (0 lines of context).

              This variable also specifies the amount of context given  for  search  results.  If
              positive,  this  many  lines  will be given before a match, if 0, the match will be
              top-aligned.

       pager_format
              Type: string
              Default: "-%Z- %C/%m: %-20.20n   %s%*  -- (%P)"

              This variable controls the format of the one-line message "status" displayed before
              each  message in either the internal or an external pager.  The valid sequences are
              listed in the $index_format section.

       pager_index_lines
              Type: number
              Default: 0

              Determines the number of lines of a mini-index which is shown when  in  the  pager.
              The  current  message, unless near the top or bottom of the folder, will be roughly
              one third of the way down this mini-index, giving the reader the context of  a  few
              messages  before  and after the message.  This is useful, for example, to determine
              how many messages remain to be read in the current thread.  A value of 0 results in
              no index being shown.

       pager_read_delay
              Type: number
              Default: 0

              Determines the number of seconds that must elapse after first opening a new message
              in the pager before that message will be marked as read.  A value of 0  results  in
              the  message  being  marked  read  unconditionally; for other values, navigating to
              another message or exiting the pager before the  timeout  will  leave  the  message
              marked unread.  This setting is ignored if $pager is not builtin.

       pager_skip_quoted_context
              Type: number
              Default: 0

              Determines  the  number  of  lines of context to show before the unquoted text when
              using the <skip-quoted> function. When set to a positive number at most  that  many
              lines  of  the  previous  quote are displayed. If the previous quote is shorter the
              whole quote is displayed.

              The (now deprecated) skip_quoted_offset is an alias for this variable,  and  should
              no longer be used.

       pager_stop
              Type: boolean
              Default: no

              When  set, the internal-pager will not move to the next message when you are at the
              end of a message and invoke the <next-page> function.

       pattern_format
              Type: string
              Default: "%2n %-15e  %d"

              This variable describes the format of the "pattern completion" menu. The  following
              printf(3)-style sequences are understood:
              %d     pattern description
              %e     pattern expression
              %n     index number

       pgp_auto_decode
              Type: boolean
              Default: no

              If  set,  NeoMutt  will  automatically  attempt to decrypt traditional PGP messages
              whenever the user performs an  operation  which  ordinarily  would  result  in  the
              contents  of  the  message  being operated on.  For example, if the user displays a
              pgp-traditional message which has  not  been  manually  checked  with  the  <check-
              traditional-pgp>  function,  NeoMutt  will  automatically  check  the  message  for
              traditional pgp.

       pgp_auto_inline
              Type: boolean
              Default: no

              This option controls whether NeoMutt generates old-style inline  (traditional)  PGP
              encrypted  or  signed messages under certain circumstances.  This can be overridden
              by use of the pgp menu, when inline is not required.  The GPGME  backend  does  not
              support this option.

              Note  that  NeoMutt  might automatically use PGP/MIME for messages which consist of
              more than a single MIME part.  NeoMutt can be  configured  to  ask  before  sending
              PGP/MIME messages when inline (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP
              only)

       pgp_check_exit
              Type: boolean
              Default: yes

              If set, NeoMutt will check the exit code of the  PGP  subprocess  when  signing  or
              encrypting.  A non-zero exit code means that the subprocess failed.  (PGP only)

       pgp_check_gpg_decrypt_status_fd
              Type: boolean
              Default: yes

              If   set,   NeoMutt   will   check   the   status   file   descriptor   output   of
              $pgp_decrypt_command and $pgp_decode_command  for  GnuPG  status  codes  indicating
              successful  decryption.   This  will  check  for  the  presence of DECRYPTION_OKAY,
              absence  of  DECRYPTION_FAILED,  and  that  all  PLAINTEXT   occurs   between   the
              BEGIN_DECRYPTION and END_DECRYPTION status codes.

              If   unset,   NeoMutt   will   instead   match   the   status   fd  output  against
              $pgp_decryption_okay.  (PGP only)

       pgp_clear_sign_command
              Type: command
              Default: ""

              This format is used to create an old-style "clearsigned" PGP  message.   Note  that
              the use of this format is strongly deprecated.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  Note that in this case, %r expands to the search string,
              which is a list of one or more quoted values such as email address, name, or keyid.
              (PGP only)

       pgp_decode_command
              Type: command
              Default: ""

              This format strings specifies a command which is  used  to  decode  application/pgp
              attachments.

              The PGP command formats have their own set of printf(3)-like sequences:
              %a     The value of $pgp_sign_as if set, otherwise the value of $pgp_default_key.
              %f     Expands to the name of a file containing a message.
              %p     Expands  to  PGPPASSFD=0  when  a  pass phrase is needed, to an empty string
                     otherwise. Note: This may be used with a %<...> construct.
              %r     One or more key IDs (or fingerprints if available).
              %s     Expands  to  the  name  of  a  file  containing  the  signature  part  of  a
                     multipart/signed attachment when verifying it.

              (PGP only)

       pgp_decrypt_command
              Type: command
              Default: ""

              This command is used to decrypt a PGP encrypted message.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

              Note: When decrypting messages using gpg, a pinentry program needs  to  be  invoked
              unless  the  password  is  cached  within  gpg-agent.   Currently, the pinentry-tty
              program (usually distributed with gpg) isn't suitable for being invoked by NeoMutt.
              You  are  encouraged  to  use  a different pinentry-program when running NeoMutt in
              order to avoid problems.

              See also: https://github.com/neomutt/neomutt/issues/1014

       pgp_decryption_okay
              Type: regular expression
              Default: ""

              If you assign text to  this  variable,  then  an  encrypted  PGP  message  is  only
              considered  successfully decrypted if the output from $pgp_decrypt_command contains
              the text.  This is used to  protect  against  a  spoofed  encrypted  message,  with
              multipart/encrypted  headers but containing a block that is not actually encrypted.
              (e.g. simply signed and ascii armored text).

              Note that if $pgp_check_gpg_decrypt_status_fd is set,  this  variable  is  ignored.
              (PGP only)

       pgp_default_key
              Type: string
              Default: ""

              This  is  the  default  key-pair  to  use  for PGP operations.  It will be used for
              encryption (see $postpone_encrypt and $pgp_self_encrypt).

              It will also be used for signing unless $pgp_sign_as is set.

              The (now deprecated) pgp_self_encrypt_as is an alias for this variable, and  should
              no longer be used.  (PGP only)

       pgp_encrypt_only_command
              Type: command
              Default: ""

              This command is used to encrypt a body part without signing it.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  Note that in this case, %r expands to the search string,
              which is a list of one or more quoted values such as email address, name, or keyid.
              (PGP only)

       pgp_encrypt_sign_command
              Type: command
              Default: ""

              This command is used to both sign and encrypt a body part.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_entry_format
              Type: string
              Default: "%4n %t%f %4l/0x%k %-4a %2c %u"

              This  variable  allows you to customize the PGP key selection menu to your personal
              taste. If $crypt_use_gpgme is set, then it applies to  S/MIME  key  selection  menu
              also.   This   string  is  similar  to  $index_format,  but  has  its  own  set  of
              printf(3)-like sequences:
              %a     Algorithm
              %c     Capabilities
              %f     Flags
              %i     Key fingerprint (or long key id if non-existent)
              %k     Key id
              %l     Key length
              %n     Number
              %p     Protocol
              %t     Trust/validity of the key-uid association
              %u     User id
              %[<s>] Date of the key where <s> is an strftime(3) expression

              See the section "Sending Cryptographically Signed/Encrypted Messages" of  the  user
              manual for the meaning of the letters some of these sequences expand to.

              (Crypto only) or (PGP only when GPGME disabled)

       pgp_export_command
              Type: command
              Default: ""

              This command is used to export a public key from the user's key ring.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_get_keys_command
              Type: command
              Default: ""

              This command is invoked whenever NeoMutt needs to fetch the public  key  associated
              with  an  email  address.  Of the sequences supported by $pgp_decode_command, %r is
              the only printf(3)-like sequence used with this format.  Note that in this case, %r
              expands  to  the email address, not the public key ID (the key ID is unknown, which
              is why NeoMutt is invoking this command).  (PGP only)

       pgp_good_sign
              Type: regular expression
              Default: ""

              If you assign a text to this variable, then a  PGP  signature  is  only  considered
              verified  if  the  output  from  $pgp_verify_command  contains  the  text. Use this
              variable if the exit code from the command is 0  even  for  bad  signatures.   (PGP
              only)

       pgp_ignore_subkeys
              Type: boolean
              Default: yes

              Setting  this  variable  will cause NeoMutt to ignore OpenPGP subkeys. Instead, the
              principal key will inherit the subkeys' capabilities.  Unset this if  you  want  to
              play interesting key selection games.  (PGP only)

       pgp_import_command
              Type: command
              Default: ""

              This  command  is  used  to  import a key from a message into the user's public key
              ring.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_list_pubring_command
              Type: command
              Default: ""

              This  command  is  used  to list the public key ring's contents.  The output format
              must be analogous to the one used by

              gpg --list-keys --with-colons --with-fingerprint

              Note: gpg's fixed-list-mode option should not be used.   It  produces  a  different
              date format which may result in NeoMutt showing incorrect key generation dates.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_list_secring_command
              Type: command
              Default: ""

              This command is used to list the secret key ring's  contents.   The  output  format
              must be analogous to the one used by:

              gpg --list-keys --with-colons --with-fingerprint

              Note:  gpg's  fixed-list-mode  option  should not be used.  It produces a different
              date format which may result in NeoMutt showing incorrect key generation dates.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_long_ids
              Type: boolean
              Default: yes

              If  set,  use  64  bit  PGP key IDs, if unset use the normal 32 bit key IDs.  NOTE:
              Internally, NeoMutt has transitioned to using fingerprints (or long key  IDs  as  a
              fallback).   This  option  now  only  controls  the  display  of key IDs in the key
              selection menu and a few other places.  (PGP only)

       pgp_mime_auto
              Type: quadoption
              Default: ask-yes

              This option controls whether NeoMutt will prompt you for  automatically  sending  a
              (signed/encrypted)  message using PGP/MIME when inline (traditional) fails (for any
              reason).

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP
              only)

       pgp_reply_inline
              Type: boolean
              Default: no

              Setting  this  variable  will  cause  NeoMutt to always attempt to create an inline
              (traditional) message when replying to a  message  which  is  PGP  encrypted/signed
              inline.   This  can  be  overridden  by  use  of  the  pgp menu, when inline is not
              required.  This option does not automatically detect if the (replied-to) message is
              inline;  instead  it  relies  on  NeoMutt  internals for previously checked/flagged
              messages.

              Note that NeoMutt might automatically use PGP/MIME for messages  which  consist  of
              more  than  a  single  MIME  part.  NeoMutt can be configured to ask before sending
              PGP/MIME messages when inline (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP
              only)

       pgp_retainable_sigs
              Type: boolean
              Default: no

              If  set,  signed and encrypted messages will consist of nested multipart/signed and
              multipart/encrypted body parts.

              This is useful for applications like encrypted and signed mailing lists, where  the
              outer   layer   (multipart/encrypted)  can  be  easily  removed,  while  the  inner
              multipart/signed part is retained.  (PGP only)

       pgp_self_encrypt
              Type: boolean
              Default: yes

              When set,  PGP  encrypted  messages  will  also  be  encrypted  using  the  key  in
              $pgp_default_key.  (PGP only)

       pgp_show_unusable
              Type: boolean
              Default: yes

              If  set,  NeoMutt will display non-usable keys on the PGP key selection menu.  This
              includes keys which have been  revoked,  have  expired,  or  have  been  marked  as
              "disabled" by the user.  (PGP only)

       pgp_sign_as
              Type: string
              Default: ""

              If  you  have  a  different key pair to use for signing, you should set this to the
              signing  key.   Most  people  will  only  need  to  set  $pgp_default_key.   It  is
              recommended  that  you  use  the  keyid form to specify your key (e.g. 0x00112233).
              (PGP only)

       pgp_sign_command
              Type: command
              Default: ""

              This command is used to create the detached PGP signature  for  a  multipart/signed
              PGP/MIME body part.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_sort_keys
              Type: sort order
              Default: address

              Specifies how the entries in the pgp menu  are  sorted.  The  following  are  legal
              values:
              address
                     sort alphabetically by user id
              keyid  sort alphabetically by key id
              date   sort by key creation date
              trust  sort by the trust of the key

              If  you  prefer reverse order of the above values, prefix it with "reverse-".  (PGP
              only)

       pgp_strict_enc
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will  automatically   encode   PGP/MIME   signed   messages   as
              quoted-printable.   Please  note  that unsetting this variable may lead to problems
              with non-verifyable PGP signatures, so only change this if you know  what  you  are
              doing.  (PGP only)

       pgp_timeout
              Type: number (long)
              Default: 300

              The  number  of  seconds  after  which a cached passphrase will expire if not used.
              (PGP only)

       pgp_use_gpg_agent
              Type: boolean
              Default: yes

              If set, NeoMutt expects a gpg-agent(1) process will handle private  key  passphrase
              prompts.  If unset, NeoMutt will prompt for the passphrase and pass it via stdin to
              the pgp command.

              Note that as of version 2.1, GnuPG automatically spawns an agent and  requires  the
              agent  be  used  for  passphrase  management.   Since  that version is increasingly
              prevalent, this variable now defaults set.

              NeoMutt works with a GUI or curses pinentry program.  A TTY pinentry should not  be
              used.

              If  you  are  using  an older version of GnuPG without an agent running, or another
              encryption program without an agent, you will need to unset  this  variable.   (PGP
              only)

       pgp_verify_command
              Type: command
              Default: ""

              This command is used to verify PGP signatures.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pgp_verify_key_command
              Type: command
              Default: ""

              This command is used to verify key information from the key selection menu.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible
              printf(3)-like sequences.  (PGP only)

       pipe_decode
              Type: boolean
              Default: no

              Used in connection with the <pipe-message> function.  When unset, NeoMutt will pipe
              the messages without any preprocessing. When set, NeoMutt will  attempt  to  decode
              the messages first.

              Also see $pipe_decode_weed, which controls whether headers will be weeded when this
              is set.

       pipe_decode_weed
              Type: boolean
              Default: yes

              For <pipe-message>, when $pipe_decode is set, this further controls whether NeoMutt
              will weed headers.

       pipe_sep
              Type: string
              Default: "\n"

              The  separator  to add between messages when piping a list of tagged messages to an
              external Unix command.

       pipe_split
              Type: boolean
              Default: no

              Used in connection with the <pipe-message>  function  following  <tag-prefix>.   If
              this  variable  is  unset,  when  piping  a  list  of  tagged messages NeoMutt will
              concatenate the messages and will pipe them all concatenated.   When  set,  NeoMutt
              will  pipe  the  messages  one by one.  In both cases the messages are piped in the
              current sorted order, and the $pipe_sep separator is added after each message.

       pop_auth_try_all
              Type: boolean
              Default: yes

              If set, NeoMutt will try all available authentication methods.  When unset, NeoMutt
              will  only  fall  back  to other authentication methods if the previous methods are
              unavailable. If a method is available but authentication fails,  NeoMutt  will  not
              connect to the POP server.

       pop_authenticators
              Type: string list
              Default: ""

              This is a colon-separated list of authentication methods NeoMutt may attempt to use
              to log in to an POP server, in the order NeoMutt should try  them.   Authentication
              methods  are  either  "user",  "apop"  or  any  SASL  mechanism, e.g. "digest-md5",
              "gssapi" or "cram-md5".  This option is case-insensitive. If this option  is  unset
              (the  default) NeoMutt will try all available methods, in order from most-secure to
              least-secure.

              Example:

              set pop_authenticators="digest-md5:apop:user"

       pop_check_interval
              Type: number
              Default: 60

              This variable configures how often (in seconds) NeoMutt should look for new mail in
              the currently selected mailbox if it is a POP mailbox.

       pop_delete
              Type: quadoption
              Default: ask-no

              If  set,  NeoMutt  will delete successfully downloaded messages from the POP server
              when using the <fetch-mail> function.  When unset, NeoMutt will  download  messages
              but also leave them on the POP server.

       pop_host
              Type: string
              Default: ""

              The name of your POP server for the <fetch-mail> function.  You can also specify an
              alternative port, username and password, i.e.:

              [pop[s]://][username[:password]@]popserver[:port]

              where "[...]" denotes an optional part.

       pop_last
              Type: boolean
              Default: no

              If this variable is set, NeoMutt will  try  to  use  the  "LAST"  POP  command  for
              retrieving  only  unread  messages  from the POP server when using the <fetch-mail>
              function.

       pop_oauth_refresh_command
              Type: command
              Default: ""

              The command to run  to  generate  an  OAUTH  refresh  token  for  authorizing  your
              connection  to  your  POP  server.   This  command  will be run on every connection
              attempt that uses  the  OAUTHBEARER  authentication  mechanism.   See  "oauth"  for
              details.

       pop_pass
              Type: string
              Default: ""

              Specifies the password for your POP account.  If unset, NeoMutt will prompt you for
              your password when you open a POP mailbox.

              Warning: you should only use this option when you are on a fairly  secure  machine,
              because  the superuser can read your neomuttrc even if you are the only one who can
              read the file.

       pop_reconnect
              Type: quadoption
              Default: ask-yes

              Controls whether or not NeoMutt will try to reconnect to  the  POP  server  if  the
              connection is lost.

       pop_user
              Type: string
              Default: ""

              Your login name on the POP server.

              This variable defaults to your user name on the local machine.

       post_moderated
              Type: quadoption
              Default: ask-yes

              If  set to yes, NeoMutt will post article to newsgroup that have not permissions to
              posting (e.g. moderated).  Note: if news server does not support  posting  to  that
              newsgroup or totally read-only, that posting will not have an effect.

       postpone
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are saved in the $postponed mailbox when you elect
              not to send immediately. If set to ask-yes or ask-no, you  will  be  prompted  with
              "Save (postpone) draft message?" when quitting from the "compose" screen.

              Also see the $recall variable.

       postpone_encrypt
              Type: boolean
              Default: no

              When set, postponed messages that are marked for encryption will be self-encrypted.
              NeoMutt will first try to encrypt using the value specified in $pgp_default_key  or
              $smime_default_key.    If   those   are   not  set,  it  will  try  the  deprecated
              $postpone_encrypt_as.  (Crypto only)

       postpone_encrypt_as
              Type: string
              Default: ""

              This  is  a  deprecated  fall-back  variable  for  $postpone_encrypt.   Please  use
              $pgp_default_key or $smime_default_key.  (Crypto only)

       postponed
              Type: mailbox
              Default: "~/postponed"

              NeoMutt  allows  you  to  indefinitely  "postpone  sending a message" which you are
              editing.  When you choose to postpone a message, NeoMutt saves it  in  the  mailbox
              specified by this variable.

              Also see the $postpone variable.

       preconnect
              Type: string
              Default: ""

              If  set,  a shell command to be executed if NeoMutt fails to establish a connection
              to the server. This is useful for setting up secure connections, e.g. with  ssh(1).
              If  the  command  returns  a   nonzero status, NeoMutt gives up opening the server.
              Example:

              set preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net \
              sleep 20 < /dev/null > /dev/null"

              Mailbox "foo" on "mailhost.net" can now be reached as "{localhost:1234}foo".

              Note: For this example to work, you must be able to log in to  the  remote  machine
              without having to enter a password.

       preferred_languages
              Type: string list
              Default: ""

              This  variable  specifies  a  list  of  comma-separated  languages.  RFC8255 : user
              preferred languages to be searched in parts and display.  Example:

              set preferred_languages="en,fr,de"

       print
              Type: quadoption
              Default: ask-no

              Controls whether or not NeoMutt really prints messages.  This is set to "ask-no" by
              default, because some people accidentally hit "p" often.

       print_command
              Type: command
              Default: "lpr"

              This specifies the command pipe that should be used to print messages.

       print_decode
              Type: boolean
              Default: yes

              Used  in  connection with the <print-message> function.  If this option is set, the
              message is decoded before it  is  passed  to  the  external  command  specified  by
              $print_command.   If  this  option  is  unset, no processing will be applied to the
              message when printing it.  The latter setting may be useful if you are  using  some
              advanced  printer  filter  which  is  able  to  properly format e-mail messages for
              printing.

              Also see $print_decode_weed, which controls whether headers  will  be  weeded  when
              this is set.

       print_decode_weed
              Type: boolean
              Default: yes

              For  <print-message>,  when  $print_decode  is  set,  this further controls whether
              NeoMutt will weed headers.

       print_split
              Type: boolean
              Default: no

              Used in connection with the <print-message> function.  If this option is  set,  the
              command  specified  by $print_command is executed once for each message which is to
              be printed.  If this option is unset, the command specified  by  $print_command  is
              executed  only once, and all the messages are concatenated, with a form feed as the
              message separator.

              Those who use the enscript(1) program's mail-printing mode will most likely want to
              set this option.

       prompt_after
              Type: boolean
              Default: yes

              If  you  use an external $pager, setting this variable will cause NeoMutt to prompt
              you for a command when the pager exits rather than returning to the index menu.  If
              unset, NeoMutt will return to the index menu when the external pager exits.

       query_command
              Type: command
              Default: ""

              This  specifies the command NeoMutt will use to make external address queries.  The
              string may contain a "%s", which will be substituted with the query string the user
              types.    NeoMutt   will   add  quotes  around  the  string  substituted  for  "%s"
              automatically according to shell quoting rules, so you  should  avoid  adding  your
              own.   If  no  "%s" is found in the string, NeoMutt will append the user's query to
              the         end         of         the         string.          See         "query"
              (https://neomutt.org/guide/advancedusage.html#query) for more information.

       query_format
              Type: string
              Default: "%3c %t %-25.25n %-25.25a | %e"

              This   variable   describes   the   format  of  the  "query"  menu.  The  following
              printf(3)-style sequences are understood:
              %a

                     Destination address
              %c

                     Current entry number
              %e     * Extra information
              %n

                     Destination name
              %t

                     "*" if current entry is tagged, a space otherwise
              %>X

                     Right justify the rest of the string and pad with "X"
              %|X

                     Pad to the end of the line with "X"
              %*X

                     Soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the $index_format documentation.

              * = can be optionally printed if nonzero, see the $status_format documentation.

       quit
              Type: quadoption
              Default: yes

              This variable controls whether "quit" and "exit" actually quit  from  NeoMutt.   If
              this option is set, they do quit, if it is unset, they have no effect, and if it is
              set to ask-yes or ask-no, you are prompted for confirmation when you try to quit.

              In order to quit from NeoMutt if this variable is unset, you must send  the  signal
              SIGINT  to  NeoMutt.   This  can  usually  be  achieved  by  pressing CTRL-C in the
              terminal.

       quote_regex
              Type: regular expression
              Default: "^([ \t]*[|>:}#])+"

              A regular expression used in the internal pager to  determine  quoted  sections  of
              text  in  the  body  of  a  message.  Quoted  text  may  be  filtered out using the
              <toggle-quoted> command, or colored according  to  the  "color  quoted"  family  of
              directives.

              Higher  levels  of  quoting  may  be  colored  differently ("color quoted1", "color
              quoted2", etc.). The quoting level is determined by  removing  the  last  character
              from  the  matched  text and recursively reapplying the regular expression until it
              fails to produce a match.

              Match detection may be overridden by the $smileys regular expression.

       read_inc
              Type: number
              Default: 10

              If set to a value greater  than  0,  NeoMutt  will  display  which  message  it  is
              currently  on  when  reading  a  mailbox  or when performing search actions such as
              search and limit. The message is printed after this many messages have been read or
              searched  (e.g.,  if  set to 25, NeoMutt will print a message when it is at message
              25, and then again when it gets to message 50).  This variable is meant to indicate
              progress  when reading or searching large mailboxes which may take some time.  When
              set to 0, only a single message will appear before the reading the mailbox.

              Also see the $write_inc, $net_inc and $time_inc variables and the "tuning"  section
              of the manual for performance considerations.

       read_only
              Type: boolean
              Default: no

              If set, all folders are opened in read-only mode.

       real_name
              Type: string
              Default: ""

              This  variable specifies what "real" or "personal" name should be used when sending
              messages.

              If not specified, then the user's "real name" will be read from /etc/passwd.   This
              option will not be used, if "$from" is set.

       recall
              Type: quadoption
              Default: ask-yes

              Controls  whether  or  not  NeoMutt recalls postponed messages when composing a new
              message.

              Setting this variable to yes is not generally useful,  and  thus  not  recommended.
              Note  that  the  <recall-message> function can be used to manually recall postponed
              messages.

              Also see $postponed variable.

       record
              Type: mailbox
              Default: "~/sent"

              This specifies the file into which  your  outgoing  messages  should  be  appended.
              (This  is  meant  as  the  primary  method  for saving a copy of your messages, but
              another way to do this is using the "my_hdr" command to create a "Bcc:" field  with
              your email address in it.)

              The value of $record is overridden by the $force_name and $save_name variables, and
              the "fcc-hook" command.  Also see $copy and $write_bcc.

       reflow_space_quotes
              Type: boolean
              Default: yes

              This option controls how quotes from format=flowed messages are  displayed  in  the
              pager  and  when  replying  (with  $text_flowed unset).  When set, this option adds
              spaces after each level of quote marks, turning ">>>foo" into "> > > foo".

              Note: If $reflow_text is unset, this option has no effect.  Also, this option  does
              not affect replies when $text_flowed is set.

       reflow_text
              Type: boolean
              Default: yes

              When   set,   NeoMutt   will   reformat   paragraphs  in  text/plain  parts  marked
              format=flowed.  If unset, NeoMutt will display paragraphs unaltered from  how  they
              appear in the message body.  See RFC3676 for details on the format=flowed format.

              Also see $reflow_wrap, and $wrap.

       reflow_wrap
              Type: number
              Default: 78

              This  variable  controls  the  maximum paragraph width when reformatting text/plain
              parts when $reflow_text is set.  When the value is 0, paragraphs will be wrapped at
              the terminal's right margin.  A positive value sets the paragraph width relative to
              the left margin.  A negative value set the paragraph width relative  to  the  right
              margin.

              Be  aware  that  the  reformatted  lines of a paragraph are still subject to $wrap.
              This means if $reflow_wrap  is  40  and  $wrap  is  30,  then  the  paragraph  gets
              reformatted  to  40  characters  a  line  (due to $reflow_wrap) and afterwards each
              40-character-line  is  split  at  30  characters  (due  to  $wrap),  resulting   in
              alternating line lengths of 30 and 10 characters.

              Also see $wrap.

       reply_regex
              Type: regular expression
              Default: "^((re|aw|sv)(\[[0-9]+\])*:[ \t]*)*"

              A  regular expression used to recognize reply messages when threading and replying.
              The default value corresponds to the  English  "Re:",  the  German  "Aw:"  and  the
              Swedish "Sv:".

       reply_self
              Type: boolean
              Default: no

              If  unset  and  you are replying to a message sent by you, NeoMutt will assume that
              you want to reply to the recipients of that message rather than to yourself.

              Also see the "alternates" command.

       reply_to
              Type: quadoption
              Default: ask-yes

              If set, when replying to a message, NeoMutt will use  the  address  listed  in  the
              Reply-to:  header as the recipient of the reply.  If unset, it will use the address
              in the From: header field instead.  This option is useful  for  reading  a  mailing
              list  that sets the Reply-To: header field to the list address and you want to send
              a private message to the author of a message.

       reply_with_xorig
              Type: boolean
              Default: no

              This variable provides a toggle. When active, the From: header  will  be  extracted
              from  the  current  mail's  'X-Original-To:'  header.  This  setting  does not have
              precedence over "reverse_real_name".

              Assuming 'fast_reply' is  disabled,  this  option  will  prompt  the  user  with  a
              prefilled From: header.

       resolve
              Type: boolean
              Default: yes

              When set, the cursor in a list will be automatically advanced to the next (possibly
              undeleted) message/attachment/entry whenever a command that  modifies  the  current
              message/attachment/entry is executed.

              Examples  of  such  commands are tagging a message, deleting an entry, or saving an
              attachment.

       resume_draft_files
              Type: boolean
              Default: no

              If set, draft files (specified by -H on the command line) are  processed  similarly
              to  when resuming a postponed message.  Recipients are not prompted for; send-hooks
              are not evaluated;  no  alias  expansion  takes  place;  user-defined  headers  and
              signatures are not added to the message.

       resume_edited_draft_files
              Type: boolean
              Default: yes

              If  set,  draft  files  previously edited (via -E -H on the command line) will have
              $resume_draft_files automatically set when they are used as a draft file again.

              The  first  time  a  draft  file   is   saved,   NeoMutt   will   add   a   header,
              X-Mutt-Resume-Draft to the saved file.  The next time the draft file is read in, if
              NeoMutt sees the header, it will set $resume_draft_files.

              This option is designed to prevent multiple signatures, user-defined  headers,  and
              other processing effects from being made multiple times to the draft file.

       reverse_alias
              Type: boolean
              Default: no

              This variable controls whether or not NeoMutt will display the "personal" name from
              your aliases in the index menu if it finds an  alias  that  matches  the  message's
              sender.  For example, if you have the following alias:

              alias juser abd30425@somewhere.net (Joe User)

              and then you receive mail which contains the following header:

              From: abd30425@somewhere.net

              It   would   be   displayed   in   the   index   menu  as  "Joe  User"  instead  of
              "abd30425@somewhere.net."  This is useful when the person's e-mail address  is  not
              human friendly.

       reverse_name
              Type: boolean
              Default: no

              It  may  sometimes  arrive  that  you  receive  mail to a certain machine, move the
              messages to another machine, and reply to some the messages from  there.   If  this
              variable  is  set,  the default From: line of the reply messages is built using the
              address where you received the messages you are replying to if that address matches
              your  "alternates".   If  the  variable is unset, or the address that would be used
              doesn't match your "alternates", the From:  line  will  use  your  address  on  the
              current machine.

              Also see the "alternates" command and $reverse_real_name.

       reverse_real_name
              Type: boolean
              Default: yes

              This variable fine-tunes the behavior of the $reverse_name feature.

              When  it  is  unset,  NeoMutt will remove the real name part of a matching address.
              This allows the use of the email address without having to also use what the sender
              put in the real name field.

              When it is set, NeoMutt will use the matching address as-is.

              In either case, a missing real name will be filled in afterwards using the value of
              $real_name.

       rfc2047_parameters
              Type: boolean
              Default: yes

              When this variable is set, NeoMutt will decode RFC2047-encoded MIME parameters. You
              want  to  set  this variable when NeoMutt suggests you to save attachments to files
              named like:

              =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=
              =?utf-8?Q?z=C4=99ta.png?=

              When this variable is set interactively, the  change  won't  be  active  until  you
              change folders.

              Note  that this use of RFC2047's encoding is explicitly prohibited by the standard,
              but nevertheless encountered in the wild and produced by, e.g., Outlook.

              Also note that setting this  parameter  will  not  have  the  effect  that  NeoMutt
              generates  this  kind  of  encoding.  Instead, NeoMutt will unconditionally use the
              encoding specified in RFC2231.

       save_address
              Type: boolean
              Default: no

              If set, NeoMutt will take the sender's full address when choosing a default  folder
              for  saving  a  mail. If $save_name or $force_name is set too, the selection of the
              Fcc folder will be changed as well.

       save_empty
              Type: boolean
              Default: yes

              When unset, mailboxes which contain no saved messages will be removed  when  closed
              (the exception is $spool_file which is never removed).  If set, mailboxes are never
              removed.

              Note: This only applies to mbox and MMDF folders, NeoMutt does not  delete  MH  and
              Maildir directories.

       save_history
              Type: number
              Default: 0

              This  variable  controls  the  size  of  the  history  (per  category) saved in the
              $history_file file.

              Setting this to a value greater than $history is  possible.   However,  there  will
              never be more than $history entries to select from even if more are recorded in the
              history file.

       save_name
              Type: boolean
              Default: no

              This variable controls how copies of outgoing messages  are  saved.   When  set,  a
              check  is  made to see if a mailbox specified by the recipient address exists (this
              is done by searching for a mailbox in the $folder directory with the username  part
              of  the  recipient  address).   If the mailbox exists, the outgoing message will be
              saved to that mailbox, otherwise the message is saved to the $record mailbox.

              Also see the $force_name variable.

       save_unsubscribed
              Type: boolean
              Default: no

              When set, info about unsubscribed newsgroups will be saved into "newsrc"  file  and
              into cache.

       score
              Type: boolean
              Default: yes

              When  this  variable  is  unset,  scoring  is  turned  off.   This can be useful to
              selectively disable scoring for certain folders  when  the  $score_threshold_delete
              variable and related are used.

       score_threshold_delete
              Type: number
              Default: -1

              Messages  which have been assigned a score equal to or lower than the value of this
              variable are automatically marked for deletion by NeoMutt.   Since  NeoMutt  scores
              are always greater than or equal to zero, the default setting of this variable will
              never mark a message for deletion.

       score_threshold_flag
              Type: number
              Default: 9999

              Messages which have been assigned a score greater than or equal to this  variable's
              value are automatically marked "flagged".

       score_threshold_read
              Type: number
              Default: -1

              Messages  which have been assigned a score equal to or lower than the value of this
              variable are automatically marked as read by NeoMutt.   Since  NeoMutt  scores  are
              always  greater  than  or  equal to zero, the default setting of this variable will
              never mark a message read.

       search_context
              Type: number
              Default: 0

              For the pager, this variable specifies the number  of  lines  shown  before  search
              results. By default, search results will be top-aligned.

       send_charset
              Type: string list
              Default: "us-ascii:iso-8859-1:utf-8"

              A  colon-delimited  list  of character sets for outgoing messages. NeoMutt will use
              the first character set into which the text can  be  converted  exactly.   If  your
              $charset  is  not  "iso-8859-1"  and  recipients  may not understand "UTF-8", it is
              advisable to include in the list an appropriate widely used standard character  set
              (such  as  "iso-8859-2",  "koi8-r"  or  "iso-2022-jp")  either  instead of or after
              "iso-8859-1".

              In case the text can't be  converted  into  one  of  these  exactly,  NeoMutt  uses
              $charset as a fallback.

       sendmail
              Type: command
              Default: "/usr/sbin/sendmail -oem -oi"

              Specifies  the program and arguments used to deliver mail sent by NeoMutt.  NeoMutt
              expects that the specified program interprets  additional  arguments  as  recipient
              addresses.   NeoMutt  appends  all  recipients  after adding a -- delimiter (if not
              already   present).    Additional    flags,    such    as    for    $use_8bit_mime,
              $use_envelope_from, $dsn_notify, or $dsn_return will be added before the delimiter.

              See also: $write_bcc.

       sendmail_wait
              Type: number
              Default: 0

              Specifies  the number of seconds to wait for the $sendmail process to finish before
              giving up and putting delivery in the background.

              NeoMutt interprets the value of this variable as follows:
              >0     number of seconds to wait for sendmail to finish before continuing
              0      wait forever for sendmail to finish
              <0     always put sendmail in the background without waiting

              Note that if you specify a value other than 0, the output of the child process will
              be  put  in  a  temporary file.  If there is some error, you will be informed as to
              where to find the output.

       shell
              Type: command
              Default: "/bin/sh"

              Command to use when spawning a subshell.  If not specified, then the  user's  login
              shell from /etc/passwd is used.

       show_multipart_alternative
              Type: string
              Default: ""

              When  set  to  info,  the  multipart/alternative information is shown.  When set to
              inline, all of the alternatives are displayed.  When not set, the default  behavior
              is to show only the chosen alternative.

       show_new_news
              Type: boolean
              Default: yes

              If  set,  news  server  will  be  asked for new newsgroups on entering the browser.
              Otherwise, it will be done only once for a news server.  Also controls  whether  or
              not number of new articles of subscribed newsgroups will be then checked.

       show_only_unread
              Type: boolean
              Default: no

              If  set,  only subscribed newsgroups that contain unread articles will be displayed
              in browser.

       sidebar_component_depth
              Type: number
              Default: 0

              By default the sidebar will show  the  mailbox's  path,  relative  to  the  $folder
              variable.  This  specifies the number of parent directories to hide from display in
              the sidebar. For example: If a maildir is normally  displayed  in  the  sidebar  as
              dir1/dir2/dir3/maildir,   setting  sidebar_component_depth=2  will  display  it  as
              dir3/maildir, having truncated the 2 highest directories.

              See also: $sidebar_short_path

       sidebar_delim_chars
              Type: string
              Default: "/."

              This contains the list of characters which  you  would  like  to  treat  as  folder
              separators for displaying paths in the sidebar.

              Local mail is often arranged in directories: 'dir1/dir2/mailbox'.

              set sidebar_delim_chars='/'

              IMAP mailboxes are often named: 'folder1.folder2.mailbox'.

              set sidebar_delim_chars='.'

              See also: $sidebar_short_path, $sidebar_folder_indent, $sidebar_indent_string.

       sidebar_divider_char
              Type: string
              Default: "|"

              The default is a Unicode vertical line.

              This  specifies  the  characters to be drawn between the sidebar (when visible) and
              the other NeoMutt panels. ASCII and Unicode line-drawing characters are supported.

              The divider char can be set to an empty string for some  extra  space.   If  empty,
              setting  the  sidebar_background  color may help distinguish the sidebar from other
              panels.

       sidebar_folder_indent
              Type: boolean
              Default: no

              Set this to indent mailboxes in the sidebar.

              See also: $sidebar_short_path, $sidebar_indent_string, $sidebar_delim_chars.

       sidebar_format
              Type: string
              Default: "%D%*  %n"

              This variable allows you to customize the sidebar display. This string  is  similar
              to $index_format, but has its own set of printf(3)-like sequences:
              %B

                     Name of the mailbox
              %d     * @ Number of deleted messages in the mailbox
              %D

                     Descriptive name of the mailbox
              %F     * Number of flagged messages in the mailbox
              %L     * @ Number of messages after limiting
              %n

                     "N" if mailbox has new mail, " " (space) otherwise
              %N     * Number of unread messages in the mailbox (seen or unseen)
              %o     * Number of old messages in the mailbox (unread, seen)
              %r     * Number of read messages in the mailbox (read, seen)
              %S     * Size of mailbox (total number of messages)
              %t     * @ Number of tagged messages in the mailbox
              %Z     * Number of new messages in the mailbox (unread, unseen)
              %!

                     "!"  :  one  flagged  message; "!!" : two flagged messages; "n!" : n flagged
                     messages (for n > 2).  Otherwise prints nothing.
              %>X

                     Right justify the rest of the string and pad with "X"
              %|X

                     Pad to the end of the line with "X"
              %*X

                     Soft-fill with character "X" as pad

              * = Can be optionally printed if nonzero

              @ = Only applicable to the current folder

              In order to use %S, %N, %F, and %!, $mail_check_stats must be set.  When thus  set,
              a suggested value for this option is "%B%<F? [%F]>%* %<N?%N/>%S".

       sidebar_indent_string
              Type: string
              Default: "  "

              This  specifies  the  string  that  is used to indent mailboxes in the sidebar.  It
              defaults to two spaces.

              See also: $sidebar_short_path, $sidebar_folder_indent, $sidebar_delim_chars.

       sidebar_new_mail_only
              Type: boolean
              Default: no

              When set, the sidebar will only display mailboxes containing new, or flagged, mail.

              See also: sidebar_pin, $sidebar_non_empty_mailbox_only.

       sidebar_next_new_wrap
              Type: boolean
              Default: no

              When set, the <sidebar-next-new> command will not stop at the end of  the  list  of
              mailboxes,  but  wrap  around  to  the beginning. The <sidebar-prev-new> command is
              similarly affected, wrapping around to the end of the list.

       sidebar_non_empty_mailbox_only
              Type: boolean
              Default: no

              When set, the sidebar will only display mailboxes that contain one or more mails.

              See also: $sidebar_new_mail_only, sidebar_pin.

       sidebar_on_right
              Type: boolean
              Default: no

              When set, the sidebar will appear on the right-hand side of the screen.

       sidebar_short_path
              Type: boolean
              Default: no

              By default the sidebar will show  the  mailbox's  path,  relative  to  the  $folder
              variable.  Setting  sidebar_shortpath=yes  will  shorten  the names relative to the
              previous name. Here's an example:
              shortpath=no
                     shortpath=yes shortpath=yes, folderindent=yes, indentstr=".."
              fruit  fruit fruit
              fruit.apple
                     apple ..apple
              fruit.banana
                     banana ..banana
              fruit.cherry
                     cherry ..cherry

              See  also:  $sidebar_delim_chars,  $sidebar_folder_indent,  $sidebar_indent_string,
              $sidebar_component_depth.

       sidebar_sort_method
              Type: sort order
              Default: order

              Specifies  how to sort mailbox entries in the sidebar.  By default, the entries are
              unsorted.  Valid values:
              ‐ path (alphabetically)
              ‐ count (all message count)
              ‐ flagged (flagged message count)
              ‐ unread (unread message count)
              ‐ unsorted

              You may optionally use the "reverse-"  prefix  to  specify  reverse  sorting  order
              (example: "set sidebar_sort_method=reverse-path").

              The  alpha  and  name  values are synonyms for path. The new value is a synonym for
              unread.

       sidebar_visible
              Type: boolean
              Default: no

              This specifies whether or not to show sidebar. The sidebar shows a list of all your
              mailboxes.

              See also: $sidebar_format, $sidebar_width

       sidebar_width
              Type: number
              Default: 30

              This  controls  the  width  of the sidebar.  It is measured in screen columns.  For
              example:  sidebar_width=20  could  display  20  ASCII  characters,  or  10  Chinese
              characters.

       sig_dashes
              Type: boolean
              Default: yes

              If  set,  a line containing "-- " (note the trailing space) will be inserted before
              your $signature.  It is strongly recommended  that  you  not  unset  this  variable
              unless your signature contains just your name.  The reason for this is because many
              software packages use "-- \n" to detect your signature.  For example,  NeoMutt  has
              the ability to highlight the signature in a different color in the built-in pager.

       sig_on_top
              Type: boolean
              Default: no

              If  set, the signature will be included before any quoted or forwarded text.  It is
              strongly recommended that you do not set this variable unless you really know  what
              you are doing, and are prepared to take some heat from netiquette guardians.

       signature
              Type: path
              Default: "~/.signature"

              Specifies  the  filename  of  your  signature,  which  is  appended to all outgoing
              messages.   If the filename ends with a pipe ("|"), it is assumed that filename  is
              a shell command and input should be read from its standard output.

       simple_search
              Type: string
              Default: "~f %s | ~s %s"

              Specifies  how NeoMutt should expand a simple search into a real search pattern.  A
              simple search is one that does not contain any of the "~" pattern  operators.   See
              "patterns" for more information on search patterns.

              simple_search   applies  to  several  functions,  e.g.  <delete-pattern>,  <limit>,
              searching in the index, and all of the index colors.

              For example, if you simply type "joe" at a search or  limit  prompt,  NeoMutt  will
              automatically  expand  it to the value specified by this variable by replacing "%s"
              with the supplied string.  For the default value, "joe" would be expanded  to:  "~f
              joe | ~s joe".

       size_show_bytes
              Type: boolean
              Default: no

              If  set,  message  sizes  will  display bytes for values less than 1 kilobyte.  See
              formatstrings-size.

       size_show_fractions
              Type: boolean
              Default: yes

              If set, message sizes will be displayed with a single decimal value for sizes  from
              0 to 10 kilobytes and 1 to 10 megabytes.  See formatstrings-size.

       size_show_mb
              Type: boolean
              Default: yes

              If  set, message sizes will display megabytes for values greater than or equal to 1
              megabyte.  See formatstrings-size.

       size_units_on_left
              Type: boolean
              Default: no

              If set, message sizes units will be displayed to  the  left  of  the  number.   See
              formatstrings-size.

       sleep_time
              Type: number
              Default: 1

              Specifies  time,  in  seconds,  to  pause  while  displaying  certain informational
              messages, while moving from folder to folder and after expunging messages from  the
              current  folder.   The  default is to pause one second, so a value of zero for this
              option suppresses the pause.

       smart_wrap
              Type: boolean
              Default: yes

              Controls the display of lines longer than the screen width in the  internal  pager.
              If  set,  long  lines  are  wrapped at a word boundary.  If unset, lines are simply
              wrapped at the screen edge. Also see the $markers variable.

       smileys
              Type: regular expression
              Default: "(>From )|(:[-^]?[][)(><}{|/DP])"

              The pager uses this variable to catch some common false positives of  $quote_regex,
              most  notably  smileys  and  not  consider  a  line  quoted text if it also matches
              $smileys. This mostly happens at the beginning of a line.

       smime_ask_cert_label
              Type: boolean
              Default: yes

              This flag controls whether you want to be asked to enter a label for a  certificate
              about to be added to the database or not. It is set by default.  (S/MIME only)

       smime_ca_location
              Type: path
              Default: ""

              This  variable  contains  the  name of either a directory, or a file which contains
              trusted certificates for use with OpenSSL.  (S/MIME only)

       smime_certificates
              Type: path
              Default: ""

              Since for S/MIME there is no pubring/secring as with PGP,  NeoMutt  has  to  handle
              storage and retrieval of keys by itself. This is very basic right now, and keys and
              certificates are stored in two different directories, both named as the  hash-value
              retrieved from OpenSSL. There is an index file which contains mailbox-address keyid
              pairs, and which can be manually edited. This option points to the location of  the
              certificates.  (S/MIME only)

       smime_decrypt_command
              Type: command
              Default: ""

              This   format   string   specifies   a   command   which   is   used   to   decrypt
              application/pkcs7-mime attachments.

              The OpenSSL command formats have their own set of printf(3)-like sequences  similar
              to PGP's:
              %f     Expands to the name of a file containing a message.
              %s     Expands  to  the  name  of  a  file  containing  the  signature  part  of  a
                     multipart/signed attachment when verifying it.
              %k     The key-pair specified with $smime_default_key
              %i     Intermediate certificates
              %c     One or more certificate IDs.
              %a     The algorithm used for encryption.
              %d     The message digest algorithm specified with $smime_sign_digest_alg.
              %C     CA location:  Depending on whether $smime_ca_location points to a  directory
                     or   file,   this   expands  to  "-CApath  $smime_ca_location"  or  "-CAfile
                     $smime_ca_location".

              For examples on how to configure these formats, see the smime.rc  in  the  samples/
              subdirectory  which  has been installed on your system alongside the documentation.
              (S/MIME only)

       smime_decrypt_use_default_key
              Type: boolean
              Default: yes

              If set (default) this  tells  NeoMutt  to  use  the  default  key  for  decryption.
              Otherwise,  if managing multiple certificate-key-pairs, NeoMutt will try to use the
              mailbox-address to determine the key to use. It will ask you to supply a key, if it
              can't find one.  (S/MIME only)

       smime_default_key
              Type: string
              Default: ""

              This  is  the default key-pair to use for S/MIME operations, and must be set to the
              keyid (the hash-value that OpenSSL generates) to work properly.

              It will be used for encryption (see $postpone_encrypt and $smime_self_encrypt).

              It will be used for decryption unless $smime_decrypt_use_default_key is unset.

              It will also be used for signing unless $smime_sign_as is set.

              The (now deprecated) smime_self_encrypt_as is  an  alias  for  this  variable,  and
              should no longer be used.  (S/MIME only)

       smime_encrypt_command
              Type: command
              Default: ""

              This command is used to create encrypted S/MIME messages.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible
              printf(3)-like sequences.  (S/MIME only)

              Encrypt the message to $smime_default_key  too.   (S/MIME  only)  Note:  On  Debian
              systems,  this  defaults  to  the  first  existing  file  in  the  following  list:
              ~/.smime/ca-certificates.crt                                 ~/.smime/ca-bundle.crt
              /etc/ssl/certs/ca-certificates.crt.

       smime_encrypt_with
              Type: string
              Default: "aes256"

              This  sets  the  algorithm  that  should be used for encryption.  Valid choices are
              "aes128",  "aes192",  "aes256",  "des",  "des3",  "rc2-40",  "rc2-64",   "rc2-128".
              (S/MIME only)

       smime_get_cert_command
              Type: command
              Default: ""

              This command is used to extract X509 certificates from a PKCS7 structure.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible
              printf(3)-like sequences.  (S/MIME only)

       smime_get_cert_email_command
              Type: command
              Default: ""

              This command is used  to  extract  the  mail  address(es)  used  for  storing  X509
              certificates,  and  for verification purposes (to check whether the certificate was
              issued for the sender's mailbox).

              This is a format  string,  see  the  $smime_decrypt_command  command  for  possible
              printf(3)-like sequences.  (S/MIME only)

       smime_get_signer_cert_command
              Type: command
              Default: ""

              This  command  is  used  to extract only the signers X509 certificate from a S/MIME
              signature, so that the certificate's owner may get compared to the email's  "From:"
              field.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible
              printf(3)-like sequences.  (S/MIME only)

       smime_import_cert_command
              Type: command
              Default: ""

              This command is used to import a certificate via smime_keys.

              This is a format  string,  see  the  $smime_decrypt_command  command  for  possible
              printf(3)-like  sequences.   NOTE: %c and %k will default to $smime_sign_as if set,
              otherwise $smime_default_key.  (S/MIME only)

       smime_is_default
              Type: boolean
              Default: no

              The default  behavior  of  NeoMutt  is  to  use  PGP  on  all  auto-sign/encryption
              operations. To override and to use OpenSSL instead this must be set.  However, this
              has no effect while replying, since NeoMutt  will  automatically  select  the  same
              application  that  was  used to sign/encrypt the original message.  (Note that this
              variable can be overridden by unsetting $crypt_auto_smime.)  (S/MIME only)

       smime_keys
              Type: path
              Default: ""

              Since for S/MIME there is no pubring/secring as with PGP,  NeoMutt  has  to  handle
              storage  and  retrieval  of keys/certs by itself. This is very basic right now, and
              stores keys and certificates in  two  different  directories,  both  named  as  the
              hash-value   retrieved  from  OpenSSL.  There  is  an  index  file  which  contains
              mailbox-address keyid pair, and which can be manually edited. This option points to
              the location of the private keys.  (S/MIME only)

       smime_pk7out_command
              Type: command
              Default: ""

              This  command is used to extract PKCS7 structures of S/MIME signatures, in order to
              extract the public X509 certificate(s).

              This is a format  string,  see  the  $smime_decrypt_command  command  for  possible
              printf(3)-like sequences.  (S/MIME only)

       smime_self_encrypt
              Type: boolean
              Default: yes

              When set, S/MIME encrypted messages will also be encrypted using the certificate in
              $smime_default_key.  (S/MIME only)

       smime_sign_as
              Type: string
              Default: ""

              If you have a separate key to use for signing, you should set this to  the  signing
              key. Most people will only need to set $smime_default_key.  (S/MIME only)

       smime_sign_command
              Type: command
              Default: ""

              This  command  is used to created S/MIME signatures of type multipart/signed, which
              can be read by all mail clients.

              This is a format  string,  see  the  $smime_decrypt_command  command  for  possible
              printf(3)-like sequences.  (S/MIME only)

       smime_sign_digest_alg
              Type: string
              Default: "sha256"

              This  sets  the  algorithm  that  should  be used for the signature message digest.
              Valid choices are "md5", "sha1", "sha224", "sha256", "sha384",  "sha512".   (S/MIME
              only)

       smime_timeout
              Type: number
              Default: 300

              The  number  of  seconds  after  which a cached passphrase will expire if not used.
              (S/MIME only)

       smime_verify_command
              Type: command
              Default: ""

              This command is used to verify S/MIME signatures of type multipart/signed.

              This is a format  string,  see  the  $smime_decrypt_command  command  for  possible
              printf(3)-like sequences.  (S/MIME only)

       smime_verify_opaque_command
              Type: command
              Default: ""

              This command is used to verify S/MIME signatures of type application/pkcs7-mime.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible
              printf(3)-like sequences.  (S/MIME only)

       smtp_authenticators
              Type: string list
              Default: ""

              This is a colon-separated list of authentication methods NeoMutt may attempt to use
              to  log in to an SMTP server, in the order NeoMutt should try them.  Authentication
              methods are any SASL mechanism, e.g. "plain", "digest-md5", "gssapi" or "cram-md5".
              This  option  is  case-insensitive. If it is "unset" (the default) NeoMutt will try
              all available methods, in order from most-secure to least-secure. Support  for  the
              "plain"  mechanism  is  bundled;  other mechanisms are provided by an external SASL
              library (look for '+sasl' in the output of neomutt -v).

              Example:

              set smtp_authenticators="digest-md5:cram-md5"

       smtp_oauth_refresh_command
              Type: command
              Default: ""

              The command to run  to  generate  an  OAUTH  refresh  token  for  authorizing  your
              connection  to  your  SMTP  server.   This  command will be run on every connection
              attempt that uses  the  OAUTHBEARER  or  XOAUTH2  authentication  mechanisms.   See
              "oauth" for details.

       smtp_pass
              Type: string
              Default: ""

              Specifies  the  password  for your SMTP account.  If unset, NeoMutt will prompt you
              for your password when you first send mail via SMTP.  See  $smtp_url  to  configure
              NeoMutt to send mail via SMTP.

              Warning:  you  should only use this option when you are on a fairly secure machine,
              because the superuser can read your neomuttrc even if you are the only one who  can
              read the file.

       smtp_url
              Type: string
              Default: ""

              Defines  the  SMTP  smarthost where sent messages should relayed for delivery. This
              should take the form of an SMTP URL, e.g.:

              smtp[s]://[user[:pass]@]host[:port]

              where "[...]" denotes an optional part.  Setting this variable overrides the  value
              of the $sendmail variable.

              Also see $write_bcc.

       smtp_user
              Type: string
              Default: ""

              The username for the SMTP server.

              This variable defaults to your user name on the local machine.

       socket_timeout
              Type: number
              Default: 30

              Causes NeoMutt to timeout any socket connect/read/write operation (for IMAP, POP or
              SMTP)  after  this  many  seconds.   A  negative  value  causes  NeoMutt  to   wait
              indefinitely.

       sort
              Type: sort order
              Default: date

              Specifies how to sort messages in the "index" menu.  Valid values are:
              ‐ date
              ‐ date-received
              ‐ from
              ‐ score
              ‐ size
              ‐ spam
              ‐ subject
              ‐ threads
              ‐ to
              ‐ unsorted

              You  may  optionally use the "reverse-" prefix to specify reverse sorting order, or
              the "last-" prefix to sort threads based on the corresponding attribute of the last
              descendant  rather  than  the thread root.  If both prefixes are in use, "reverse-"
              must come before "last-".  The "last-" prefix has no effect on a flat view.

              Any ties in the primary  sort  are  broken  by  $sort_aux.   When  $use_threads  is
              "threads"  or  "reverse", $sort controls the sorting between threads, and $sort_aux
              controls the sorting within a thread.

              The "date-sent" value is a synonym for  "date".  The  "mailbox-order"  value  is  a
              synonym for "unsorted".

              The  values  of "threads" and "reverse-threads" are legacy options, which cause the
              value of $sort_aux to also control sorting between threads, and  they  may  not  be
              used  with  the "last-" prefix.  The preferred way to enable a threaded view is via
              $use_threads.   This  variable  can  also  be  set  via  the   <sort-mailbox>   and
              <sort-reverse> functions.

              Note:  When $use_threads is "threads", the last thread sorts to the bottom; when it
              is "reversed", the last thread sorts to the top.  The use of  "reverse-"  in  $sort
              swaps which end the last thread will sort to.

              See  the  "Use  Threads  Feature"  section  for  further  explanation and examples,
              https://neomutt.org/feature/use-threads

       sort_alias
              Type: sort order
              Default: alias

              Specifies how the entries in the "alias" menu are sorted.  The following are  legal
              values:
              ‐ address (sort alphabetically by email address)
              ‐ alias (sort alphabetically by alias name)
              ‐ unsorted (leave in order specified in .neomuttrc)

              Note:  This  also  affects  the entries of the address query menu, thus potentially
              overruling the order of entries as generated by $query_command.

       sort_aux
              Type: sort order
              Default: date

              This provides a secondary sort for messages in the  "index"  menu,  used  when  the
              $sort value is equal for two messages.

              When  sorting by threads, this variable controls how subthreads are sorted within a
              single thread (for the order between threads, see $sort).  This can be set  to  any
              value  that  $sort  can, including with the use of "reverse-" and "last-" prefixes,
              except for variations using "threads" (in that case, NeoMutt will just use "date").
              For instance,

              set sort_aux=last-date-received

              would  mean  that  if a new message is received in a thread, that subthread becomes
              the last one displayed (or the first, if you have "set use_threads=reverse".)  When
              using  $use_threads,  it  is  more  common  to  use "last-" with $sort and not with
              $sort_aux.

              See the "Use  Threads  Feature"  section  for  further  explanation  and  examples,
              https://neomutt.org/feature/use-threads

       sort_browser
              Type: sort order
              Default: alpha

              Specifies  how  to  sort  entries in the file browser.  By default, the entries are
              sorted alphabetically.  Valid values:
              ‐ alpha (alphabetically)
              ‐ count (all message count)
              ‐ date
              ‐ desc (description)
              ‐ new (new message count)
              ‐ size
              ‐ unsorted

              You may optionally use the "reverse-"  prefix  to  specify  reverse  sorting  order
              (example: "set sort_browser=reverse-date").

              The "unread" value is a synonym for "new".

       browser_sort_dirs_first
              Type: boolean
              Default: no

              If this variable is set, the browser will group directories before files.

       sort_re
              Type: boolean
              Default: yes

              This  variable  is  only useful when sorting by threads with $strict_threads unset.
              In that case, it changes the heuristic neomutt uses to thread messages by  subject.
              With  $sort_re  set,  neomutt  will  only  attach a message as the child of another
              message by subject if the subject of the child  message  starts  with  a  substring
              matching the setting of $reply_regex.  With $sort_re unset, neomutt will attach the
              message whether or not this is the case, as long as the non-$reply_regex  parts  of
              both messages are identical.

       spam_separator
              Type: string
              Default: ","

              This  variable  controls  what  happens  when multiple spam headers are matched: if
              unset, each successive header will overwrite any previous  matches  value  for  the
              spam  label.  If set, each successive match will append to the previous, using this
              variable's value as a separator.

       spool_file
              Type: mailbox
              Default: ""

              If your spool mailbox is in a non-default place where NeoMutt can't  find  it,  you
              can specify its location with this variable. The description from "named-mailboxes"
              or "virtual-mailboxes" may be used for the spool_file.

              If not specified, then  the  environment  variables  $MAIL  and  $MAILDIR  will  be
              checked.

       ssl_ca_certificates_file
              Type: path
              Default: ""

              This  variable  specifies  a  file  containing trusted CA certificates.  Any server
              certificate that is signed with one of these CA certificates is also  automatically
              accepted. (GnuTLS only)

              Example:

              set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt

              Note: On Debian systems, this option is set by default to “threads” in /etc/Muttrc.

       ssl_ciphers
              Type: string
              Default: ""

              Contains a colon-separated list of ciphers to use when using SSL.  For OpenSSL, see
              ciphers(1) for the syntax of the string.

              For GnuTLS, this option will be used in place of  "NORMAL"  at  the  start  of  the
              priority  string.   See  gnutls_priority_init(3)  for  the syntax and more details.
              (Note: GnuTLS version 2.1.7 or higher is required.)

       ssl_client_cert
              Type: path
              Default: ""

              The file containing a client certificate and its associated private key.

       ssl_force_tls
              Type: boolean
              Default: yes

              If this variable is set, NeoMutt  will  require  that  all  connections  to  remote
              servers  be  encrypted.  Furthermore  it  will attempt to negotiate TLS even if the
              server does not advertise the capability, since it would otherwise  have  to  abort
              the connection anyway. This option supersedes $ssl_starttls.

       ssl_min_dh_prime_bits
              Type: number
              Default: 0

              This  variable specifies the minimum acceptable prime size (in bits) for use in any
              Diffie-Hellman key exchange. A value of 0 will use  the  default  from  the  GNUTLS
              library. (GnuTLS only)

       ssl_starttls
              Type: quadoption
              Default: yes

              If  set  (the default), NeoMutt will attempt to use STARTTLS on servers advertising
              the capability. When unset, NeoMutt will not attempt to use STARTTLS regardless  of
              the server's capabilities.

              Note  that STARTTLS is subject to many kinds of attacks, including the ability of a
              machine-in-the-middle  to   suppress   the   advertising   of   support.    Setting
              $ssl_force_tls is recommended if you rely on STARTTLS.

       ssl_use_sslv2
              Type: boolean
              Default: no

              If  set  ,  NeoMutt will use SSLv2 when communicating with servers that request it.
              N.B. As of 2011, SSLv2 is  considered  insecure,  and  using  is  inadvisable.  See
              https://tools.ietf.org/html/rfc6176 (OpenSSL only)

       ssl_use_sslv3
              Type: boolean
              Default: no

              If  set  ,  NeoMutt will use SSLv3 when communicating with servers that request it.
              N.B. As of 2015, SSLv3 is considered insecure, and using  it  is  inadvisable.  See
              https://tools.ietf.org/html/rfc7525

       ssl_use_system_certs
              Type: boolean
              Default: yes

              If  set  to  yes,  NeoMutt  will use CA certificates in the system-wide certificate
              store when checking if a server certificate is signed by  a  trusted  CA.  (OpenSSL
              only)

       ssl_use_tlsv1
              Type: boolean
              Default: no

              If  set , NeoMutt will use TLSv1.0 when communicating with servers that request it.
              N.B. As of 2015, TLSv1.0 is considered insecure, and using it is  inadvisable.  See
              https://tools.ietf.org/html/rfc7525

       ssl_use_tlsv1_1
              Type: boolean
              Default: no

              If  set , NeoMutt will use TLSv1.1 when communicating with servers that request it.
              N.B. As of 2015, TLSv1.1 is considered insecure, and using it is  inadvisable.  See
              https://tools.ietf.org/html/rfc7525

       ssl_use_tlsv1_2
              Type: boolean
              Default: yes

              If set , NeoMutt will use TLSv1.2 when communicating with servers that request it.

       ssl_use_tlsv1_3
              Type: boolean
              Default: yes

              If set , NeoMutt will use TLSv1.3 when communicating with servers that request it.

       ssl_verify_dates
              Type: boolean
              Default: yes

              If  set  (the  default), NeoMutt will not automatically accept a server certificate
              that is either not yet valid or already expired. You should  only  unset  this  for
              particular known hosts, using the <account-hook> function.

       ssl_verify_host
              Type: boolean
              Default: yes

              If  set  (the  default), NeoMutt will not automatically accept a server certificate
              whose host name does not match the host used in your folder URL.  You  should  only
              unset this for particular known hosts, using the <account-hook> function.

       ssl_verify_partial_chains
              Type: boolean
              Default: no

              This  option  should not be changed from the default unless you understand what you
              are doing.

              Setting this variable to yes will permit verifying partial certification chains, i.
              e.  a  certificate chain where not the root, but an intermediate certificate CA, or
              the host certificate, are marked trusted (in  $certificate_file),  without  marking
              the root signing CA as trusted.

              (OpenSSL 1.0.2b and newer only).

       status_chars
              Type: character string
              Default: "-*%A"

              Controls the characters used by the "%r" indicator in $status_format.
              Character
                     Default Description
              1      - Mailbox is unchanged
              2      * Mailbox has been changed and needs to be resynchronized
              3      %  Mailbox  is  read-only,  or  will  not be written when exiting.  (You can
                     toggle whether to  write  changes  to  a  mailbox  with  the  <toggle-write>
                     operation, bound by default to "%")
              4      A  Folder opened in attach-message mode.  (Certain operations like composing
                     a new mail, replying, forwarding, etc. are not permitted in this mode)

       status_format
              Type: string
              Default: "-%r-NeoMutt: %D [Msgs:%<M?%M/>%m%<n? New:%n>%<o? Old:%o>%<d? Del:%d>%<F? Flag:%F>%<t? Tag:%t>%<p? Post:%p>%<b? Inc:%b>%<l? %l>]---(%<T?%T/>%s/%S)-%>-(%P)---"

              Controls the format of the status line displayed in the "index" menu.  This  string
              is similar to $index_format, but has its own set of printf(3)-like sequences:
              %b     * Number of mailboxes with new mail
              %d     * Number of deleted messages
              %D

                     Description of the mailbox
              %f

                     The full pathname of the current mailbox
              %F     * Number of flagged messages
              %h

                     Local hostname
              %l     * Size (in bytes) of the current mailbox (see formatstrings-size)
              %L     *  Size  (in  bytes)  of  the  messages shown (i.e., which match the current
                     limit) (see formatstrings-size)
              %m     * The number of messages in the mailbox
              %M     * The number of messages shown (i.e., which match the current limit)
              %n     * Number of new messages in the mailbox (unread, unseen)
              %o     * Number of old messages in the mailbox (unread, seen)
              %p     * Number of postponed messages
              %P

                     Percentage of the way through the index
              %r

                     Modified/read-only/won't-write/attach-message   indicator,   According    to
                     $status_chars
              %R     * Number of read messages in the mailbox (read, seen)
              %s

                     Current sorting mode ($sort)
              %S

                     Current aux sorting method ($sort_aux)
              %t     * Number of tagged messages in the mailbox
              %T     * Current threading mode ($use_threads)
              %u     * Number of unread messages in the mailbox (seen or unseen)
              %v

                     NeoMutt version string
              %V     * Currently active limit pattern, if any
              %>X

                     Right justify the rest of the string and pad with "X"
              %|X

                     Pad to the end of the line with "X"
              %*X

                     Soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the $index_format documentation.

              * = can be optionally printed if nonzero

              Some of the above sequences can be used to optionally print a string if their value
              is nonzero.  For example, you may only want to see the number of  flagged  messages
              if  such  messages exist, since zero is not particularly meaningful.  To optionally
              print a string based upon one of the above sequences, the  following  construct  is
              used:

              %<sequence_char?optional_string>

              where sequence_char is a character from the table above, and optional_string is the
              string you would like printed if sequence_char  is  nonzero.   optional_string  may
              contain other sequences as well as normal text.

              Here  is an example illustrating how to optionally print the number of new messages
              in a mailbox:

              %<n?%n new messages>

              You can also switch between two strings using the following construct:

              %<sequence_char?if_string&else_string>

              If the value of sequence_char is non-zero, if_string will  be  expanded,  otherwise
              else_string will be expanded.

              As  another example, here is how to show either $sort and $sort_aux or $use_threads
              and $sort, based on whether threads are enabled with $use_threads:

              %<T?%s/%S&%T/%s>

              You can force the  result  of  any  printf(3)-like  sequence  to  be  lowercase  by
              prefixing  the  sequence  character with an underscore ("_") sign.  For example, if
              you want to display the local hostname in lowercase, you would use: "%_h".

              If you prefix the sequence character with a colon  (":")  character,  NeoMutt  will
              replace  any  dots in the expansion by underscores. This might be helpful with IMAP
              folders that don't like dots in folder names.

       status_on_top
              Type: boolean
              Default: no

              Setting this variable causes the "status bar" to be displayed on the first line  of
              the screen rather than near the bottom. If $help is set too, it'll be placed at the
              bottom.

       strict_threads
              Type: boolean
              Default: no

              If set, threading will only make use of the "In-Reply-To" and "References:"  fields
              when  you $sort by message threads.  By default, messages with the same subject are
              grouped together in "pseudo threads.". This may not always be desirable, such as in
              a  personal  mailbox  where  you  might  have  several  unrelated messages with the
              subjects like "hi" which will get grouped together. See also $sort_re  for  a  less
              drastic way of controlling this behavior.

       suspend
              Type: boolean
              Default: yes

              When  unset,  NeoMutt  won't  stop  when  the user presses the terminal's susp key,
              usually "^Z". This is useful if you run NeoMutt inside an  xterm  using  a  command
              like "xterm -e neomutt".

              On startup NeoMutt tries to detect if it is the process session leader.  If so, the
              default of suspend  is  "no"  otherwise  "yes".   This  default  covers  the  above
              mentioned use case of "xterm -e neomutt".

       text_flowed
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  generate  "format=flowed"  bodies with a content type of
              "text/plain; format=flowed".  This format is easier  to  handle  for  some  mailing
              software,  and  generally  just  looks like ordinary text.  To actually make use of
              this format's features, you'll need support in your editor.

              The option only controls  newly  composed  messages.   Postponed  messages,  resent
              messages, and draft messages (via -H on the command line) will use the content-type
              of the source message.

              Note that $indent_string is ignored when this option is set.

       thorough_search
              Type: boolean
              Default: yes

              Affects the ~b, ~B, and ~h search operations described in section  "patterns".   If
              set, the headers and body/attachments of messages to be searched are decoded before
              searching. If unset, messages are searched as they appear in the folder.

              Users searching attachments or for  non-ASCII  characters  should  set  this  value
              because  decoding  also  includes  MIME parsing/decoding and possible character set
              conversions. Otherwise NeoMutt will  attempt  to  match  against  the  raw  message
              received  (for  example quoted-printable encoded or with encoded headers) which may
              lead to incorrect search results.

       thread_received
              Type: boolean
              Default: no

              If $strict_threads is unset, then messages may also be grouped by subject.   Unlike
              threading  by "In-Reply-To:" and "References:" header, grouping by subject does not
              imply a parent-child relation between two messages.

              To determine the ancestry between messages grouped by subject, Neomutt  uses  their
              date: only newer messages can be descendants of older ones.

              When  $thread_received  is set, NeoMutt uses the date received rather than the date
              sent when comparing messages for the date.

              See also $strict_threads, and $sort_re.

       tilde
              Type: boolean
              Default: no

              When set, the internal-pager will pad blank lines to the bottom of the screen  with
              a tilde ("~").

       time_inc
              Type: number
              Default: 0

              Along  with  $read_inc,  $write_inc,  and  $net_inc,  this  variable  controls  the
              frequency with which progress updates are displayed.  It  suppresses  updates  less
              than $time_inc milliseconds apart. This can improve throughput on systems with slow
              terminals, or when running NeoMutt on a remote system.

              Also see the "tuning" section of the manual for performance considerations.

       timeout
              Type: number
              Default: 600

              When NeoMutt is waiting for user input either idling in menus or in an  interactive
              prompt,  NeoMutt would block until input is present. Depending on the context, this
              would prevent certain operations from  working,  like  checking  for  new  mail  or
              keeping an IMAP connection alive.

              This  variable  controls how many seconds NeoMutt will at most wait until it aborts
              waiting for input, performs these operations and continues to wait for input.

              A value of zero or less will cause NeoMutt to never time out.

       tmp_dir
              Type: path
              Default: "/tmp"

              This variable allows you to specify where NeoMutt will place  its  temporary  files
              needed for displaying and composing messages.

              If  this  variable  is  not set, the environment variable $TMPDIR is used.  Failing
              that, then "/tmp" is used.

       to_chars
              Type: character string
              Default: " +TCFLR"

              Controls the character used to indicate mail addressed to you.
              Character
                     Default Description
              1      <space> The mail is not addressed to your address.
              2      + You are the only recipient of the message.
              3      T Your address appears in the "To:" header field, but you are not  the  only
                     recipient of the message.
              4      C  Your  address is specified in the "Cc:" header field, but you are not the
                     only recipient.
              5      F Indicates the mail that was sent by you.
              6      L Indicates the mail was sent to a mailing-list you subscribe to.
              7      R Your address appears in the "Reply-To:" header field but none of the above
                     applies.

       toggle_quoted_show_levels
              Type: number
              Default: 0

              Quoted  text  may  be  filtered out using the <toggle-quoted> command.  If set to a
              number greater than 0, then the <toggle-quoted> command will only filter out  quote
              levels above this number.

       trash
              Type: mailbox
              Default: ""

              If set, this variable specifies the path of the trash folder where the mails marked
              for deletion will be moved, instead of being irremediably purged.

              NOTE: When you delete a message in the trash folder, it is really deleted, so  that
              you have a way to clean the trash.

       ts_enabled
              Type: boolean
              Default: no

              Controls whether NeoMutt tries to set the terminal status line and icon name.  Most
              terminal emulators emulate the status line in the window title.

       ts_icon_format
              Type: string
              Default: "M%<n?AIL&ail>"

              Controls the format of the icon title, as  long  as  "$ts_enabled"  is  set.   This
              string is identical in formatting to the one used by "$status_format".

       ts_status_format
              Type: string
              Default: "NeoMutt with %<m?%m messages&no messages>%<n? [%n NEW]>"

              Controls  the  format  of the terminal status line (or window title), provided that
              "$ts_enabled" has been set. This string is identical in formatting to the one  used
              by "$status_format".

       tunnel
              Type: command
              Default: ""

              Setting  this  variable will cause NeoMutt to open a pipe to a command instead of a
              raw socket. You may be able to use this to set up preauthenticated  connections  to
              your IMAP/POP3/SMTP server. Example:

              set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"

              Note:  For  this  example  to work you must be able to log in to the remote machine
              without having to enter a password.

              When set, NeoMutt uses the tunnel for all remote connections.  Please see "account-
              hook" in the manual for how to use different tunnel commands per connection.

       tunnel_is_secure
              Type: boolean
              Default: yes

              When  set,  NeoMutt will assume the $tunnel connection does not need STARTTLS to be
              enabled.  It will also allow IMAP PREAUTH  server  responses  inside  a  tunnel  to
              proceed.   This  is  appropriate if $tunnel uses ssh or directly invokes the server
              locally.

              When unset, NeoMutt will negotiate  STARTTLS  according  to  the  ssl_starttls  and
              ssl_force_tls variables.  If ssl_force_tls is set, NeoMutt will abort connecting if
              an IMAP server responds with PREAUTH.  This setting is appropriate if $tunnel  does
              not provide security and could be tampered with by attackers.

       uncollapse_jump
              Type: boolean
              Default: no

              When  set,  NeoMutt  will jump to the next unread message, if any, when the current
              thread is uncollapsed.

       uncollapse_new
              Type: boolean
              Default: yes

              When set, NeoMutt will automatically uncollapse any collapsed thread that  receives
              a new message. When unset, collapsed threads will remain collapsed. the presence of
              the new message will still affect index sorting, though.

       use_8bit_mime
              Type: boolean
              Default: no

              Warning: do not set this variable unless you are using a version of sendmail  which
              supports  the  -B8BITMIME  flag  (such as sendmail 8.8.x) or you may not be able to
              send mail.

              When set, NeoMutt will invoke $sendmail with the -B8BITMIME flag when sending 8-bit
              messages to enable ESMTP negotiation.

       use_domain
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  qualify  all  local  addresses (ones without the "@host"
              portion) with the value of $hostname.  If unset, no addresses will be qualified.

       use_envelope_from
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  set  the   envelope   sender   of   the   message.    If
              $envelope_from_address  is  set,  it  will be used as the sender address. If unset,
              NeoMutt will attempt to derive the sender from the "From:" header.

              Note that this information is passed to sendmail command using the -f command  line
              switch.  Therefore  setting  this  option  is  not useful if the $sendmail variable
              already contains -f or if the executable pointed to by  $sendmail  doesn't  support
              the -f switch.

       use_from
              Type: boolean
              Default: yes

              When set, NeoMutt will generate the "From:" header field when sending messages.  If
              unset, no "From:" header field will be generated unless the  user  explicitly  sets
              one using the "my_hdr" command.

       use_ipv6
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will look for IPv6 addresses of hosts it tries to contact.  If
              this option is unset, NeoMutt will restrict itself to  IPv4  addresses.   Normally,
              the default should work.

       use_threads
              Type: enumeration
              Default: unset

              The  style  of  threading  used  in the index. May be one of "flat" (no threading),
              "threads" (threaded, with subthreads below root message)  or  "reverse"  (threaded,
              with  subthreads above root message). For convenience, the value "yes" is a synonym
              for "threads", and "no" is a synonym for "flat".

              If this variable is never set, then  $sort  controls  whether  threading  is  used,
              $sort_aux   controls  both  the  sorting  of  threads  and  subthreads,  and  using
              <sort-mailbox> to select threads affects only $sort.  Once this  variable  is  set,
              attempting  to  set  $sort to a value using "threads" will warn, the value of $sort
              controls the sorting between threads while  $sort_aux  controls  sorting  within  a
              thread, and <sort-mailbox> toggles $use_threads.

              Example:

              set use_threads=yes

              See the "Use Threads Feature" section for further explanation and examples.

       user_agent
              Type: boolean
              Default: no

              When  set, NeoMutt will add a "User-Agent:" header to outgoing messages, indicating
              which version of NeoMutt was used for composing them.

       virtual_spool_file
              Type: boolean
              Default: no

              This command is now unnecessary. $spool_file has been extended to  support  mailbox
              descriptions as a value.

              When   set,   NeoMutt   will   use   the   first   defined   virtual  mailbox  (see
              virtual-mailboxes) as a spool file.

       wait_key
              Type: boolean
              Default: yes

              Controls whether NeoMutt will ask you to press a key after an external command  has
              been  invoked  by  these  functions:  <shell-escape>, <pipe-message>, <pipe-entry>,
              <print-message>, and <print-entry> commands.

              It is also used when  viewing  attachments  with  "auto_view",  provided  that  the
              corresponding  mailcap  entry has a needsterminal flag, and the external program is
              interactive.

              When set, NeoMutt will always ask for a key. When unset, NeoMutt will  wait  for  a
              key only if the external command returned a non-zero status.

       weed
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  weed headers when displaying, forwarding, or replying to
              messages.

              Also see $copy_decode_weed, $pipe_decode_weed, $print_decode_weed.

       wrap
              Type: number
              Default: 0

              When set to a positive value, NeoMutt will wrap text at $wrap characters.  When set
              to  a  negative value, NeoMutt will wrap text so that there are $wrap characters of
              empty space on the right side of the terminal. Setting it  to  zero  makes  NeoMutt
              wrap at the terminal width.

              Also see $reflow_wrap.

       wrap_headers
              Type: number
              Default: 78

              This  option  specifies  the  number  of characters to use for wrapping an outgoing
              message's headers. Allowed values are between 78 and 998 inclusive.

              Note: This option usually shouldn't be changed. RFC5233 recommends a line length of
              78  (the  default),  so  please  only change this setting when you know what you're
              doing.

       wrap_search
              Type: boolean
              Default: yes

              Controls whether searches wrap around the end.

              When set, searches  will  wrap  around  the  first  (or  last)  item.  When  unset,
              incremental searches will not wrap.

       write_bcc
              Type: boolean
              Default: no

              Controls whether NeoMutt writes out the "Bcc:" header when preparing messages to be
              sent.  Some MTAs, such as Exim and Courier, do not strip the "Bcc:" header;  so  it
              is  advisable  to leave this unset unless you have a particular need for the header
              to be in the sent message.

              If NeoMutt is set to deliver directly via SMTP(see  $smtp_url),  this  option  does
              nothing: NeoMutt will never write out the "Bcc:" header in this case.

              Note  this option only affects the sending of messages.  Fcc'ed copies of a message
              will always contain the "Bcc:" header if one exists.

              Note: On Debian systems, exim4 and postfix strip BCC headers by default. The  above
              warning applies to exim3 users, see /etc/Muttrc.

       write_inc
              Type: number
              Default: 10

              When  writing  a  mailbox,  a  message will be printed every $write_inc messages to
              indicate progress.  If set to 0, only a single message  will  be  displayed  before
              writing a mailbox.

              Also  see  the $read_inc, $net_inc and $time_inc variables and the "tuning" section
              of the manual for performance considerations.

       x_comment_to
              Type: boolean
              Default: no

              If set, NeoMutt will add "X-Comment-To:" field (that contains full name of original
              article author) to article that followuped to newsgroup.
