NAME

       nanorc - GNU nano's configuration file

DESCRIPTION

       The  nanorc  files  contain  the  default  settings for nano, a small and friendly editor.
       During startup, if --rcfile is not given, nano will read two files: first the  system-wide
       settings,  from  /etc/nanorc  (the exact path might be different on your system), and then
       the user-specific settings, either from ~/.nanorc or from $XDG_CONFIG_HOME/nano/nanorc  or
       from  ~/.config/nano/nanorc,  whichever  is encountered first.  If --rcfile is given, nano
       will read just the specified settings file.

OPTIONS

       The configuration file accepts a series of set and unset commands, which can  be  used  to
       configure  nano  on  startup  without using command-line options.  Additionally, there are
       some commands to define syntax highlighting and to rebind keys --  see  the  two  separate
       sections  on those.  nano reads one command per line.  All commands and keywords should be
       written in lowercase.

       Options in nanorc files take precedence over nano's  defaults,  and  command-line  options
       override  nanorc  settings.   Also,  options  that  do  not  take an argument are unset by
       default.  So using the unset command is only needed when wanting to override a setting  of
       the  system's  nanorc  file  in  your own nanorc.  Options that take an argument cannot be
       unset.

       Quotes inside the characters  parameters below should not be  escaped.   The  last  double
       quote on the line will be seen as the closing quote.

       The supported commands and arguments are:

       set afterends
          Make Ctrl+Right and Ctrl+Delete stop at word ends instead of beginnings.

       set allow_insecure_backup
          When  backing  up  files,  allow the backup to succeed even if its permissions can't be
          (re)set due to special OS considerations.  You should NOT enable this option unless you
          are sure you need it.

       set atblanks
          When  soft  line  wrapping is enabled, make it wrap lines at blank characters (tabs and
          spaces) instead of always at the edge of the screen.

       set autoindent
          Automatically indent a newly created line to the same number of tabs and/or  spaces  as
          the  previous  line  (or  as  the  next line if the previous line is the beginning of a
          paragraph).

       set backup
          When saving a file, create a backup file by adding a tilde (~) to the file's name.

       set backupdir directory
          Make and keep not just one backup file, but make and keep a uniquely numbered one every
          time  a  file  is  saved -- when backups are enabled with set backup or --backup or -B.
          The uniquely numbered files are stored in the specified directory.

       set boldtext
          Use bold instead of reverse video for the title bar, status bar, key  combos,  function
          tags,  line  numbers, and selected text.  This can be overridden by setting the options
          titlecolor, statuscolor, keycolor, functioncolor, numbercolor, and selectedcolor.

       set bookstyle
          When justifying, treat any line that starts with  whitespace  as  the  beginning  of  a
          paragraph (unless auto-indenting is on).

       set brackets "characters"
          Set  the  characters  treated as closing brackets when justifying paragraphs.  This may
          not include blank characters.  Only closing punctuation  (see  set  punct),  optionally
          followed  by  the  specified closing brackets, can end sentences.  The default value is
          ""')>]}".

       set breaklonglines
          Automatically hard-wrap the current line when it becomes overlong.

       set casesensitive
          Do case-sensitive searches by default.

       set constantshow
          Constantly display the cursor position in the status bar.  This  overrides  the  option
          quickblank.

       set cutfromcursor
          Use cut-from-cursor-to-end-of-line by default, instead of cutting the whole line.

       set emptyline
          Do not use the line below the title bar, leaving it entirely blank.

       set errorcolor [bold,][italic,]fgcolor,bgcolor
          Use  this color combination for the status bar when an error message is displayed.  The
          default value is bold,white,red.  See set titlecolor for valid color names.

       set fill number
          Set the target width for justifying and  automatic  hard-wrapping  at  this  number  of
          columns.   If  the  value  is 0 or less, wrapping will occur at the width of the screen
          minus number columns, allowing the wrap point to vary  along  with  the  width  of  the
          screen if the screen is resized.  The default value is -8.

       set functioncolor [bold,][italic,]fgcolor,bgcolor
          Use  this color combination for the concise function descriptions in the two help lines
          at the bottom of the screen.  See set titlecolor for more details.

       set guidestripe number
          Draw a vertical stripe at the given column, to help judge the width of the text.   (The
          color of the stripe can be changed with set stripecolor.)

       set historylog
          Save  the last hundred search strings and replacement strings and executed commands, so
          they can be easily reused in later sessions.

       set indicator
          Display a "scrollbar" on the righthand side of the edit window.  It shows the  position
          of the viewport in the buffer and how much of the buffer is covered by the viewport.

       set jumpyscrolling
          Scroll the buffer contents per half-screen instead of per line.

       set keycolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination  for the shortcut key combos in the two help lines at the
          bottom of the screen.  See set titlecolor for more details.

       set linenumbers
          Display line numbers to  the  left  of  the  text  area.   (Any  line  with  an  anchor
          additionally gets a mark in the margin.)

       set locking
          Enable vim-style lock-files for when editing files.

       set magic
          When  neither  the  file's  name  nor its first line give a clue, try using libmagic to
          determine the applicable syntax.  (Calling libmagic can be relatively  time  consuming.
          It is therefore not done by default.)

       set matchbrackets "characters"
          Specify  the  opening and closing brackets that can be found by bracket searches.  This
          may not include blank characters.  The opening set must come before  the  closing  set,
          and the two sets must be in the same order.  The default value is "(<[{)>]}".

       set minibar
          Suppress  the  title  bar  and instead show information about the current buffer at the
          bottom of the screen, in the space for the status bar.  In this "minibar" the  filename
          is  shown on the left, followed by an asterisk if the buffer has been modified.  On the
          right are displayed the current line and column number, the code of the character under
          the  cursor (in Unicode format: U+xxxx), the same flags as are shown by set stateflags,
          and a percentage that expresses how far the cursor is into the file (linewise).  When a
          file  is  loaded or saved, and also when switching between buffers, the number of lines
          in the buffer is displayed after the filename.  This number is cleared  upon  the  next
          keystroke,  or replaced with an [i/n] counter when multiple buffers are open.  The line
          plus column numbers and the character code are displayed only when set constantshow  is
          used,  and can be toggled on and off with M-C.  The state flags are displayed only when
          set stateflags is used.

       set minicolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the minibar.  (When this option is  not  specified,  the
          colors of the title bar are used.)  See set titlecolor for more details.

       set mouse
          Enable  mouse support, if available for your system.  When enabled, mouse clicks can be
          used to place the cursor, set the mark (with a double click),  and  execute  shortcuts.
          The  mouse  will  work  in the X Window System, and on the console when gpm is running.
          Text can still be selected through dragging by holding down the Shift key.

       set multibuffer
          When reading in a file with ^R, insert it into a new buffer by default.

       set noconvert
          Don't convert files from DOS/Mac format.

       set nohelp
          Don't display the two help lines at the bottom of the screen.

       set nonewlines
          Don't automatically add a newline when a text does not end with one.  (This  can  cause
          you to save non-POSIX text files.)

       set nowrap
          Deprecated  option  since  it  has  become the default setting.  When needed, use unset
          breaklonglines instead.

       set numbercolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for line numbers.  See set titlecolor for more details.

       set operatingdir directory
          nano will only read and write files inside directory and its subdirectories.  Also, the
          current  directory  is  changed to here, so files are inserted from this directory.  By
          default, the operating directory feature is turned off.

       set positionlog
          Save the cursor position of files between editing sessions.   The  cursor  position  is
          remembered for the 200 most-recently edited files.

       set preserve
          Preserve the XON and XOFF keys (^Q and ^S).

       set promptcolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the prompt bar.  (When this option is not specified, the
          colors of the title bar are used.)  See set titlecolor for more details.

       set punct "characters"
          Set the characters treated as closing punctuation when justifying paragraphs.  This may
          not  include  blank  characters.   Only  the specfified closing punctuation, optionally
          followed by closing brackets (see brackets), can end sentences.  The default  value  is
          "!.?".

       set quickblank
          Make  status-bar  messages  disappear after 1 keystroke instead of after 20.  Note that
          option constantshow overrides  this.   When  option  minibar  or  zero  is  in  effect,
          quickblank makes a message disappear after 0.8 seconds instead of after the default 1.5
          seconds.

       set quotestr "regex"
          Set the regular expression for matching the quoting part of a line.  The default  value
          is  "^([ \t]*([!#%:;>|}]|//))+".   (Note  that  \t stands for an actual Tab character.)
          This makes it possible to rejustify blocks of quoted text when composing email, and  to
          rewrap blocks of line comments when writing source code.

       set rawsequences
          Interpret  escape sequences directly, instead of asking ncurses to translate them.  (If
          you need this option to get some keys to work properly,  it  means  that  the  terminfo
          terminal  description  that  is  used  does not fully match the actual behavior of your
          terminal.  This can happen when you ssh into a BSD machine, for example.)   Using  this
          option disables nano's mouse support.

       set rebinddelete
          Interpret  the  Delete and Backspace keys differently so that both Backspace and Delete
          work properly.  You should only use this option when on your  system  either  Backspace
          acts like Delete or Delete acts like Backspace.

       set regexp
          Do  regular-expression  searches  by  default.   Regular expressions in nano are of the
          extended type (ERE).

       set saveonexit
          Save a changed buffer automatically on exit (^X); don't prompt.

       set scrollercolor fgcolor,bgcolor
          Use this color combination for the indicator alias "scrollbar".  (On terminal emulators
          that  link  to a libvte older than version 0.55, using a background color here does not
          work correctly.)  See set titlecolor for more details.

       set selectedcolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for selected text.  See set titlecolor for more details.

       set showcursor
          Put the cursor on the highlighted item in the file browser, and show the cursor in  the
          help viewer, to aid braille users and people with poor vision.

       set smarthome
          Make  the Home key smarter.  When Home is pressed anywhere but at the very beginning of
          non-whitespace characters on a line, the cursor will jump  to  that  beginning  (either
          forwards or backwards).  If the cursor is already at that position, it will jump to the
          true beginning of the line.

       set softwrap
          Display lines that exceed the screen's width over multiple screen lines.  (You can make
          this soft-wrapping occur at whitespace instead of rudely at the screen's edge, by using
          also set atblanks.)

       set speller "program [argument ...]"
          Use the given program to do spell checking and correcting, instead of using the  built-
          in corrector that calls hunspell(1) or spell(1).

       set spotlightcolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination  for  highlighting  a search match.  The default value is
          black,lightyellow.  See set titlecolor for valid color names.

       set stateflags
          Use the top-right corner of the screen for showing  some  state  flags:  I  when  auto-
          indenting,  M  when  the mark is on, L when hard-wrapping (breaking long lines), R when
          recording a macro, and S when soft-wrapping.  When the buffer is modified, a  star  (*)
          is shown after the filename in the center of the title bar.

       set statuscolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the status bar.  See set titlecolor for more details.

       set stripecolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination  for the vertical guiding stripe.  See set titlecolor for
          more details.

       set tabsize number
          Use a tab size of number columns.  The value of number must be  greater  than  0.   The
          default value is 8.

       set tabstospaces
          Convert each typed tab to spaces -- to the number of spaces that a tab at that position
          would take up.

       set titlecolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the title bar.   Valid  names  for  the  foreground  and
          background colors are: red, green, blue, magenta, yellow, cyan, white, and black.  Each
          of these eight names may be prefixed with the word light to get a brighter  version  of
          that  color.   The  word  grey  or  gray  may  be used as a synonym for lightblack.  On
          terminal emulators that can do at least 256  colors,  other  valid  (but  unprefixable)
          color  names  are: pink, purple, mauve, lagoon, mint, lime, peach, orange, latte, rosy,
          beet, plum, sea, sky, slate, teal, sage, brown, ocher, sand, tawny, brick, crimson, and
          normal  --  where  normal  means  the  default foreground or background color.  On such
          emulators, the color may also be specified as a three-digit hexadecimal number prefixed
          with #, with the digits representing the amounts of red, green, and blue, respectively.
          This tells nano to select from the available palette the color  that  approximates  the
          given values.

          Either  "fgcolor"  or  ",bgcolor" may be left out, and the pair may be preceded by bold
          and/or italic (separated by commas) to get a bold and/or  slanting  typeface,  if  your
          terminal can do those.

       set trimblanks
          Remove  trailing  whitespace  from wrapped lines when automatic hard-wrapping occurs or
          when text is justified.

       set unix
          Save a file by default in Unix format.   This  overrides  nano's  default  behavior  of
          saving  a file in the format that it had.  (This option has no effect when you also use
          set noconvert.)

       set whitespace "characters"
          Set the two characters used to indicate the presence of tabs and spaces.  They must  be
          single-column  characters.   The default pair for a UTF-8 locale is "»⋅", and for other
          locales ">.".

       set wordbounds
          Detect word boundaries differently by  treating  punctuation  characters  as  parts  of
          words.

       set wordchars "characters"
          Specify  which  other  characters  (besides  the  normal  alphanumeric  ones) should be
          considered as parts of words.  When using this  option,  you  probably  want  to  unset
          wordbounds.

       set zap
          Let  an  unmodified  Backspace  or  Delete erase the marked region (instead of a single
          character, and without affecting the cutbuffer).

       set zero
          Hide all elements of the interface (title bar, status bar, and help lines) and use  all
          rows  of  the  terminal for showing the contents of the buffer.  The status bar appears
          only when there is a significant message, and disappears after 1.5 seconds or upon  the
          next  keystroke.   With M-Z the title bar plus status bar can be toggled.  With M-X the
          help lines.

NOTES

       Option set suspendable has been removed.  Suspension is enabled by default, reachable  via
       ^T^Z.  (If you want a plain ^Z to suspend nano, add bind ^Z suspend main to your nanorc.)

SYNTAX HIGHLIGHTING

       Coloring  the  different syntactic elements of a file is done via regular expressions (see
       the color command below).  This is inherently imperfect, because regular  expressions  are
       not powerful enough to fully parse a file.  Nevertheless, regular expressions can do a lot
       and are easy to make, so they are a good fit for a small editor like nano.

       All regular expressions in nano are POSIX extended regular expressions.  This  means  that
       .,  ?,  *,  +,  ^,  $, and several other characters are special.  The period . matches any
       single character, ? means the preceding item is optional, * means the preceding  item  may
       be  matched  zero  or  more  times, + means the preceding item must be matched one or more
       times, ^ matches the beginning of a line, and $ the end, \< matches the start of  a  word,
       and  \>  the end, and \s matches a blank.  It also means that lookahead and lookbehind are
       not possible.  A complete explanation can be found in the manual page  of  GNU  grep:  man
       grep.

       For each kind of file a separate syntax can be defined via the following commands:

       syntax name ["fileregex" ...]
              Start  the  definition  of a syntax with this name.  All subsequent color and other
              such commands will be  added  to  this  syntax,  until  a  new  syntax  command  is
              encountered.

              When  nano  is  run,  this  syntax  will  be automatically activated if the current
              filename matches the extended regular expression fileregex.  Or the syntax  can  be
              explicitly  activated  by  using the -Y or --syntax command-line option followed by
              the name.

              The syntax default is special: it takes no fileregex, and  applies  to  files  that
              don't  match  any  syntax's regexes.  The syntax none is reserved; specifying it on
              the command line is the same as not having a syntax at all.

       header "regex" ...
              If from all defined syntaxes no fileregex matched,  then  compare  this  regex  (or
              regexes)  against  the  first  line  of the current file, to determine whether this
              syntax should be used for it.

       magic "regex" ...
              If no fileregex matched and no header regex matched either, then compare this regex
              (or  regexes)  against  the result of querying the magic database about the current
              file, to determine whether this syntax should be used for it.  (This  functionality
              only  works  when  libmagic is installed on the system and will be silently ignored
              otherwise.)

       formatter program [argument ...]
              Run the given program on the full contents of the current buffer.

       linter program [argument ...]
              Use the given program to run a syntax check on the current buffer.

       comment "string"
              Use the given string for commenting and uncommenting lines.  If the string contains
              a  vertical  bar or pipe character (|), this designates bracket-style comments; for
              example, "/*|*/" for CSS files.  The characters before the pipe  are  prepended  to
              the line and the characters after the pipe are appended at the end of the line.  If
              no pipe character is present, the full string is prepended; for  example,  "#"  for
              Python files.  If empty double quotes are specified, the comment/uncomment function
              is disabled; for example, "" for JSON.  The default value is "#".

       tabgives "string"
              Make the <Tab> key produce the given string.  Useful for languages like Python that
              want  to  see  only  spaces  for  indentation.   This  overrides the setting of the
              tabstospaces option.

       color [bold,][italic,]fgcolor,bgcolor "regex" ...
              Paint all pieces of text that match the extended regular expression regex with  the
              given  foreground  and  background colors, at least one of which must be specified.
              Valid color names are: red, green, blue, magenta, yellow, cyan, white,  and  black.
              Each  of  these  eight  names may be prefixed with the word light to get a brighter
              version of that color.  The word grey  or  gray  may  be  used  as  a  synonym  for
              lightblack.   On  terminal  emulators  that can do at least 256 colors, other valid
              (but unprefixable) color names are: pink, purple, mauve, lagoon, mint, lime, peach,
              orange,  latte,  rosy, beet, plum, sea, sky, slate, teal, sage, brown, ocher, sand,
              tawny, brick, crimson, and normal -- where normal means the default  foreground  or
              background  color.   On such emulators, the color may also be specified as a three-
              digit hexadecimal number prefixed with #, with the digits representing the  amounts
              of  red,  green,  and  blue,  respectively.   This  tells  nano  to select from the
              available palette the color that approximates the given values.

              The color pair may be preceded by bold and/or italic (separated by commas) to get a
              bold and/or slanting typeface, if your terminal can do those.

              All  coloring  commands are applied in the order in which they are specified, which
              means that later commands can recolor stuff that was colored earlier.

       icolor [bold,][italic,]fgcolor,bgcolor "regex" ...
              Same as above, except that the matching is case insensitive.

       color [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
              Paint all pieces of text whose start matches extended regular expression fromrx and
              whose  end  matches  extended regular expression torx with the given foreground and
              background colors, at least one of which must be specified.  This means that, after
              an  initial  instance  of fromrx, all text until the first instance of torx will be
              colored.  This allows syntax highlighting to span multiple lines.

       icolor [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
              Same as above, except that the matching is case insensitive.

       include "syntaxfile"
              Read in self-contained color syntaxes from syntaxfile.  Note  that  syntaxfile  may
              contain only the above commands, from syntax to icolor.

       extendsyntax name command argument ...
              Extend  the  syntax  previously  defined as name with another command.  This allows
              adding a new color, icolor, header, magic, formatter, linter, comment, or  tabgives
              command  to an already defined syntax -- useful when you want to slightly improve a
              syntax defined in one  of  the  system-installed  files  (which  normally  are  not
              writable).

REBINDING KEYS

       Key bindings can be changed via the following three commands:

          bind key function menu
                 Rebinds  the  given key to the given function in the given menu (or in all menus
                 where the function exists when all is used).

          bind key "string" menu
                 Makes the given key produce the given string in the given menu (or in all  menus
                 where  the  key  exists  when  all  is used).  The string can consist of text or
                 commands or a mix of them.  (To enter a command into  the  string,  precede  its
                 keystroke with M-V.)

          unbind key menu
                 Unbinds  the  given  key  from  the  given menu (or from all menus where the key
                 exists when all is used).

       The format of key should be one of:

          ^X     where X is a Latin letter, or one of several ASCII characters (@, ], \,  ^,  _),
                 or the word "Space".  Example: ^C.

          M-X    where X is any ASCII character except [, or the word "Space".  Example: M-8.

          Sh-M-X where  X  is  a  Latin  letter.   Example: Sh-M-U.  By default, each Meta+letter
                 keystroke does the same as the corresponding Shift+Meta+letter.   But  when  any
                 Shift+Meta bind is made, that will no longer be the case, for all letters.

          FN     where  N is a numeric value from 1 to 24.  Example: F10.  (Often, F13 to F24 can
                 be typed as F1 to F12 with Shift.)

          Ins or Del.

       Rebinding ^M (Enter) or ^I (Tab) is probably not a good idea.  Rebinding ^[ (Esc)  is  not
       possible, because its keycode is the starter byte of Meta keystrokes and escape sequences.
       Rebinding any of the dedicated cursor-moving keys  (the  arrows,  Home,  End,  PageUp  and
       PageDown) is not possible.  On some terminals it's not possible to rebind ^H (unless --raw
       is used) because its keycode is identical to that of the Backspace key.

       Valid function names to be bound are:

          help
            Invokes the help viewer.

          cancel
            Cancels the current command.

          exit
            Exits from the program (or from the help viewer or file browser).

          writeout
            Writes the current buffer to disk, asking for a name.

          savefile
            Writes the current file to disk without prompting.

          insert
            Inserts a file into the current buffer (at the current cursor position),  or  into  a
            new buffer when option multibuffer is set.

          whereis
            Starts a forward search for text in the current buffer -- or for filenames matching a
            string in the current list in the file browser.

          wherewas
            Starts a backward search for text in the current buffer -- or for filenames  matching
            a string in the current list in the file browser.

          findprevious
            Searches the next occurrence in the backward direction.

          findnext
            Searches the next occurrence in the forward direction.

          replace
            Interactively replaces text within the current buffer.

          cut
            Cuts and stores the current line (or the marked region).

          copy
            Copies the current line (or the marked region) without deleting it.

          paste
            Pastes  the  currently  stored  text  into  the  current buffer at the current cursor
            position.

          zap
            Throws away the current line (or the marked region).   (This  function  is  bound  by
            default to <Meta+Delete>.)

          chopwordleft
            Deletes  from  the  cursor  position  to  the beginning of the preceding word.  (This
            function is bound by default to <Shift+Ctrl+Delete>.  If your  terminal  produces  ^H
            for  <Ctrl+Backspace>,  you  can make <Ctrl+Backspace> delete the word to the left of
            the cursor by rebinding ^H to this function.)

          chopwordright
            Deletes from the cursor position to the beginning of the next word.   (This  function
            is bound by default to <Ctrl+Delete>.)

          cutrestoffile
            Cuts all text from the cursor position till the end of the buffer.

          mark
            Sets  the mark at the current position, to start selecting text.  Or, when it is set,
            unsets the mark.

          location
            Reports the current position of the cursor in  the  buffer:  the  line,  column,  and
            character positions.

          wordcount
            Counts  and  reports  on the status bar the number of lines, words, and characters in
            the current buffer (or in the marked region).

          execute
            Prompts for a program to execute.  The program's output will  be  inserted  into  the
            current buffer (or into a new buffer when M-F is toggled).

          speller
            Invokes  a spell-checking program, either the default hunspell(1) or GNU spell(1), or
            the one defined by --speller or set speller.

          formatter
            Invokes a full-buffer-processing program (if the active syntax  defines  one).   (The
            current buffer is written out to a temporary file, the program is run on it, and then
            the temporary file is read back in, replacing the contents of the buffer.)

          linter
            Invokes a syntax-checking program (if  the  active  syntax  defines  one).   If  this
            program produces lines of the form "filename:linenum:charnum: some message", then the
            cursor will be put at the indicated position in  the  mentioned  file  while  showing
            "some  message"  on the status bar.  You can move from message to message with <PgUp>
            and <PgDn>, and leave linting mode with ^C or <Enter>.

          justify
            Justifies the current paragraph (or the marked region).  A paragraph is  a  group  of
            contiguous  lines  that,  apart  from  possibly  the  first  line,  all have the same
            indentation.  The beginning of a paragraph is detected by either this lone line  with
            a differing indentation or by a preceding blank line.

          fulljustify
            Justifies the entire current buffer (or the marked region).

          indent
            Indents (shifts to the right) the current line or the marked lines.

          unindent
            Unindents (shifts to the left) the current line or the marked lines.

          comment
            Comments  or uncomments the current line or the marked lines, using the comment style
            specified in the active syntax.

          complete
            Completes (when possible) the fragment  before  the  cursor  to  a  full  word  found
            elsewhere in the current buffer.

          left
            Goes left one position (in the editor or browser).

          right
            Goes right one position (in the editor or browser).

          up
            Goes one line up (in the editor or browser).

          down
            Goes one line down (in the editor or browser).

          scrollup
            Scrolls the viewport up one row (meaning that the text slides down) while keeping the
            cursor in the same text position, if possible.  (This function is bound by default to
            <Alt+Up>.    If   <Alt+Up>   does  nothing  on  your  Linux  console,  see  the  FAQ:
            ⟨https://nano-editor.org/dist/latest/faq.html#4.1⟩.)

          scrolldown
            Scrolls the viewport down one row (meaning that the text slides up) while keeping the
            cursor in the same text position, if possible.  (This function is bound by default to
            <Alt+Down>.)

          center
            Scrolls the line with the cursor to the middle of the screen.

          prevword
            Moves the cursor to the beginning of the previous word.

          nextword
            Moves the cursor to the beginning of the next word.

            Moves the cursor to the beginning of the current line.

          end
            Moves the cursor to the end of the current line.

          beginpara
            Moves the cursor to the beginning of the current paragraph.

          endpara
            Moves the cursor to the end of the current paragraph.

          prevblock
            Moves the cursor to the beginning of the current or preceding block of text.  (Blocks
            are separated by one or more blank lines.)

          nextblock
            Moves the cursor to the beginning of the next block of text.

          pageup
            Goes up one screenful.

          pagedown
            Goes down one screenful.

            Goes to the last line of the file.

          gotoline
            Goes  to  a specific line (and column if specified).  Negative numbers count from the
            end of the file (and end of the line).

          findbracket
            Moves the cursor to the bracket (or brace or parenthesis, etc.) that matches  (pairs)
            with the one under the cursor.  See set matchbrackets.

          anchor
            Places an anchor at the current line, or removes it when already present.  (An anchor
            is visible when line numbers are activated.)

          prevanchor
            Goes to the first anchor before the current line.

          nextanchor
            Goes to the first anchor after the current line.

          prevbuf
            Switches to editing/viewing the previous buffer when multiple buffers are open.

          nextbuf
            Switches to editing/viewing the next buffer when multiple buffers are open.

          verbatim
            Inserts the next keystroke verbatim into the file.

          tab
            Inserts a tab at the current cursor location.

            Inserts a new line below the current one.

          delete
            Deletes the character under the cursor.

          backspace
            Deletes the character before the cursor.

          recordmacro
            Starts the recording of keystrokes -- the keystrokes are stored  as  a  macro.   When
            already recording, the recording is stopped.

          runmacro
            Replays the keystrokes of the last recorded macro.

          undo
            Undoes the last performed text action (add text, delete text, etc).

          redo
            Redoes the last undone action (i.e., it undoes an undo).

          refresh
            Refreshes the screen.

          suspend
            Suspends  the  editor and returns control to the shell (until you tell the process to
            resume execution with fg).

          flipnewbuffer
            Toggles between inserting into the current buffer and into a new empty buffer.

          flipconvert
            When reading in a file, toggles between converting and not converting it from DOS/Mac
            format.  Converting is the default.

          dosformat
            When writing a file, switches to writing a DOS format (CR/LF).

          macformat
            When writing a file, switches to writing a Mac format.

          append

          prepend
            When writing a file, 'prepends' (writes at the beginning) instead of overwriting.

          backup
            When writing a file, creates a backup of the current file.

          discardbuffer
            When  about  to  write  a  file,  discard  the  current buffer without saving.  (This

          nohelp
            Toggles  the  presence  of  the  two-line  list  of key bindings at the bottom of the
            screen.  (This toggle is special: it is available in all menus except the help viewer
            and the linter.  All further toggles are available in the main menu only.)

          autoindent
            Toggles  whether  a  newly  created  line  will  contain  the  same amount of leading
            whitespace as the preceding line -- or as the next line if the preceding line is  the
            beginning of a paragraph.

          cutfromcursor
            Toggles  whether cutting text will cut the whole line or just from the current cursor
            position to the end of the line.

          breaklonglines
            Toggles whether long lines will be hard-wrapped to the next line.  (The old  name  of
            this function, 'nowrap', is deprecated.)

          tabstospaces
            Toggles whether typed tabs will be converted to spaces.

          mouse
            Toggles mouse support.
