NAME

       exmh - An introduction to the exmh mail user interface.

INTRODUCTION

       This  man  page  provides  a  quick  tour  through  some of the basic features of exmh version 2.0, which
       provides a graphical user interface to the MH mail system.

       After you read this tutorial you should be able to use exmh for your basic daily mail reading needs.  You
       will  learn  how  to  send  mail, read mail, manage your messages in folders, and adjust some of the exmh
       features by means of its Preferences user interface.

       There is much more documentation available on-line through HTML pages that are viewable from within exmh.
       In particular.  exmh-use provides information about using the more advanced features of exmh.  If you are
       already an experienced email user, you may want to just read the GETTING STARTED section  here  and  then
       skip to the exmh-use man page.  exmh-custom describes how to customize exmh to suit your needs.  exmh-ref
       lists each button and menu entry in exmh and explains what they do.  If you are an experienced exmh user,
       this may be the most useful man page for you.

       A  cleaned  up  version of these man pages appear in the 3rd edition of the book by Jerry Peek, MH & xmh:
       email for users and programmers, which is published by O'Reilly & Associates.

       Web versions of the documentation can also be found at

       http://www.beedub.com/exmh/

GETTING STARTED

       If you are already an MH or xmh user, you can start with the examples given in this tour.  If you  are  a
       new user, exmh will set up your basic MH environment.  This includes a Mail directory which will have one
       subdirectory for each mail folder, plus several files that MH mail uses for its own purposes.   You  also
       get a ~/.mh_profile file that has user settings for MH and exmh.

       Exmh  uses  the  regular  MH  programs  to  manipulate  your mail folders and messages.  This means it is
       compatible with command-line use of MH programs, and its  actions  should  be  familiar  if  you  are  an
       experienced  MH user.  If you are a new MH user, then the details of running MH programs is hidden behind
       the graphical interface.  The MH programs used by exmh are described towards the end of this man page.

       When you run exmh for the first time it checks a few things  in  your  MH  profile.   In  particular,  it
       depends  on the Draft-Folder and Unseen-Sequence profile components.  If these profile components are not
       present, a dialog appears and exmh can set them up for you.  If you do not let exmh create them  nor  set
       them  up  by  hand, exmh will not work properly.  These profile entries are described in the exmh-ref man
       page.

       Exmh has been designed to be very flexible, although it will work  just  fine  "out  of  the  box".   The
       Preference  package  used to adjust some of the settings in exmh is introduced in this man page, and some
       of the important settings are described here.  A more complete guide to customizing exmh is given in  the
       exmh-custom man page.

RUNNING EXMH

       The  command  to  start  exmh  looks  like  this:  exmh -display hostname:0 & If your DISPLAY environment
       variable is set up properly, then the -display argument is not needed, and the command is  even  simpler.
       You  do  not  need to specify a -geometry argument, although exmh supports one.  Instead, simply position
       and size the window using your window manager.  When exmh quits, it saves the geometry information so you
       don't  have  to  worry  about  it.   It does this with all its top level windows, so you can adjust their
       position once and then forget about it.  There are more command line options described  in  the  exmh-ref
       man page.

       You can add the exmh command to your startup X environment by editing your startup file (like .xsession).
       You might also want to add it to the main menu of your window manager.  The details about this vary  from
       X  system  to X system, so ask your local X guru for help.  Exmh also supports the window manager session
       protocol, which means that session-smart window managers will automatically start exmh  for  you  if  you
       quit X when exmh is running.

THE EXMH DISPLAY

       This  section  describes the main parts of the exmh display.  It probably makes sense to run exmh at this
       point so you can follow along.  There are three  sets  of  buttons  in  the  interface,  and  three  main
       subwindows.

       Main  Buttons.   Along  the  top  of  the window is a set of buttons and menus that apply to exmh itself.
       Quit, for example, quits exmh.  The Help button pops up a menu, and you can select the entries  there  to
       get  more  on-line information about exmh.  Use the left mouse button to select the buttons and menus.  A
       button will change its appearance when you press it, and it will be invoked when you  release  the  mouse
       over the button.  If you slide the mouse off the button before releasing it, nothing happens.

       Folder  Display.   Below  the  main buttons is the folder display subwindow.  It has a special button for
       each of your top-level folders, and these are called folder labels.  As a  new  user  you  will  see  two
       folder  labels,  one  for  inbox  and  drafts.  The inbox folder is for your new messages, and the drafts
       folder is for messages you are writing.  If you have used MH (or xmh) before, then you may have many more
       folders  that  will  appear  in  this display.  The mouse bindings for folder labels are explained in the
       exmh-use man page.  The Color Legend from the Help menu also tells you how the folder labels  respond  to
       mouse clicks.

       Folder  Cache.  A second folder display called the folder cache may appear under the main folder display.
       This shows the folder labels for recently used folders.  If you only  have  a  few  folders  this  wastes
       screen  real estate.  The PREFERENCES section near the end of this man page explains how to turn this off
       via the Folder Cache preferences setting.  If you are a first-time exmh user, Exmh tries to guess if  you
       need this display based on the number of folders and nested folders you have.

       Folder Buttons.  The middle set of buttons is for operations that apply to folders.  For example, you can
       create a new folder with the New button here.  The More... button displays a popup menu with several more
       operations  you can apply to folders.  Some of these buttons will be introduced in this man page.  All of
       these buttons and menus are explained in detail in the exmh-ref man page.

       To the left of the folder buttons, summary information about the current folder is displayed.

       Table of Contents.  The middle subwindow of the display shows a summary of the messages  in  the  folder.
       It  shows the message number, the date of the message, the subject of the message, and, space permitting,
       the first few words of the message.  Left click  on  a  line  in  the  table  of  contents  to  view  the
       corresponding  message.  The mouse bindings for the table of contents are described in more detail in the
       exmh-use man page.

       MH experts: The display in this window comes from both the MH scan program or MH inc programs, so  it  is
       affected by the form specification used by these programs.

       Color and Monochrome Highlights.  Both the folder display and table of contents windows use highlights to
       give you visual clues about the state of messages and folders.  Your unread messages are  highlighted  in
       the  table of contents and the folders that contain unread message are highlighted in the folder display.
       Pull down the main Help menu and select Color Legend to display a key to the highlights for your display.
       The  highlighting  is  covered  in  more detail later in the exmh-use man page.  The exmh-custom man page
       tells how you can control the highlighting yourself.

       Status Line.  Just below the table of contents is the status line.  This has two parts.   The  left  part
       shows  the  name  of  the  folder and the message number for the current message, if any.  The right part
       gives feedback about what exmh is doing.  After it displays a message, the Subject component is displayed
       there.

       Subwindow  Resize  Diamond.  The black diamond to the right of the status line is used to change the size
       of the internal windows.  Press the first mouse button on this target  and  a  horizontal  line  appears.
       Drag it up and down to adjust the window sizes.  Try dragging it all the way to the top and bottom of the
       exmh window to see how the mode changes to adjust different windows.

       Message Buttons The bottom row of buttons are for operations that apply to the current message.   Several
       of these operations will be introduced in this man page.  The right hand button labeled More... brings up
       a menu with several more advanced message operations.

       Hint: Many of these message operations have keyboard shortcuts that make it easy to use  exmh  with  your
       hands  on  the  keyboard.   Some  of  the short-cuts are introduced in this man page, and all of them are
       listed in the exmh-use man page.

       Message Display.  The bottom  subwindow  displays  the  current  message,  if  any.   Some  of  the  less
       interesting mail headers start out scrolled off the top of this window.

SENDING MAIL

       A good way to test things out is to send a message to yourself.  Here are the steps you take to do that:

       1.   Click  the Send button, which is in the Message buttons in the bottom group.  A new window will open
       that contains the template for your message.  The built-in editor, which is called sedit, will start  out
       with  the insert cursor positioned at the end of the first empty header line.  Enter your user name after
       the To: header.  If you want to send the message to more than one person, use a  comma  to  separate  the
       names.

       2.   Position the insert cursor on the next header line.  You can do this a few different ways.  The most
       direct way is to click the left mouse button where you  want  the  cursor  to  be.   There  are  keyboard
       shortcuts, too.  If you press <Tab> the editor will take you to the end of the next header line.  You can
       also use the arrow keys or some emacs-like bindings to move the cursor.  <Control-n>  goes  to  the  next
       line,  <Control-f>  moves  the  cursor forward a character.  <Control-p> moves up a line, and <Control-b>
       moves back a character.  The Simple Edit menu entry shows you all the keybindings.

       3.  The next header is the Cc: line.  People listed in the Cc: line get a "courtesy" (or  "carbon")  copy
       of  the message.  By convention, the message is primarily for the people listed in the To: component, and
       the people in the Cc: component are getting the message "for information."  In this case, you  can  leave
       the Cc: component empty.

       Move  the  insert  cursor to the Subject: line and enter a Subject.  The people that receive your message
       will get an idea of what the message is about from the subject, so take a moment to think of a good  one.
       For this test, you can type something like "exmh test message".

       4.  Make sure the headers are OK.  In particular, make sure there are no blank lines in the headers.  The
       mail system treats a blank line as meaning "end-of-headers", so you don't want  to  prematurely  end  the
       header  section.   If you have a blank line, position the insert cursor on it and use Backspace to remove
       the empty line.

       Position the cursor at the start of the message body.  You can use the mouse for this, or you  can  press
       <Tab> twice quickly and the editor will position the cursor correctly.  When using the default MH message
       templates, this will be right after the line of all dashes.

       5.  Type in your message.  When you type in a long message, the lines will  wrap  automatically  at  word
       boundaries.   To get a blank line for paragraph boundaries, press <Return>.  The built-in editor supports
       several editing commands that are based on the GNU emacs key bindings.  If you  select  the  Simple  Edit
       menu  entry  under the main Bindings menu, you will bring up a dialog that lets you view and edit the key
       bindings.

       6.  If you are happy with the message, you send it by pressing the Send button at the top-right corner of
       the window.  The Send button will turn grey, and the window will disappear once the message has been sent
       successfully.

       If you do not want to send the message, press the Abort button instead.  If you want to save the  message
       draft  and continue to work on it later, press the Save&Quit button.  Working on a saved draft message is
       described in the exmh-use man page.

       Send yourself a few messages, or have a friend send you a few test messages.  You  will  use  these  test
       messages  to  practice  moving around in a folder and deleting messages.  Make one of the messages pretty
       long so you can practice scrolling through it.

       Finally, try sending mh-mime-sample@online.ora.com a message.  This addresses a program that will  return
       a  MIME  message  to  you.   Just  put this address in the To field with anything as the message body and
       subject.  Reading this message will be described below.

MOUSING AROUND

       The selection is dragged out with the left mouse button.  You can modify the  selection  by  holding  the
       Shift key while pressing the left button.  A double-click begins a word-oriented selection, and a triple-
       click begins a line-oriented selection.  If you drag a selection off the bottom or top of  a  window  the
       text will be scrolled automatically and the selection will be extended.

       Paste is done with the middle mouse button.  The current insert point is used, not the point at which you
       middle-click.  If you drag the middle mouse button, then the window  is  scrolled  instead  as  described
       below.  There is also a key-binding for paste, which is <Control-y>.  Use <Control-w> or the <Delete> key
       to delete the selection.

       The middle mouse button is used for "drag-scrolling".  To scroll, simply press the  middle  mouse  button
       over  the  text  and drag the text.  If you press the Shift key, the scrolling is faster.  Drag-scrolling
       works in the text widgets, for vertical  scrolling,  and  the  one-line  entry  widgets,  for  horizontal
       scrolling.   The text widgets are used to display the folder contents and the current message.  The entry
       widgets are used in various dialogs in order to enter values.  You can change the scrolling button to the
       right button or to only work with shift-middle.  Set this up in the Simple Edit Bindings... dialog.

       Buttons  and menus are also sensitive to which mouse button is pressed.  Only the left button activates a
       button, and it is the <ButtonRelease> event that is important.  If you accidentally move the mouse off of
       the button as you release it, nothing will happen.  Don't worry, the wrong button will not be invoked.

       Press  the  left  button  over  a  menu  button  to   pull  down  a  menu.  Most of the menus in exmh are
       distinguished with a "..."  in their label, e.g. "More...".  The menu will go away  when  the  button  is
       released.   Release  the  mouse button off the menu if you do not want to invoke any menu item.  (In some
       versions of Tk, the middle button will "tear off" a Tk menu.  This is quite handy if  you  use  the  menu
       often.   To  get  the  menu  to  go away, you must click the left button over the menu button.  This will
       reattach the menu to the menu button, and another left click will make the menu go away.  In  the  latest
       versions of Tk, the first menu entry is a dashed line that invokes this tear-off operation.)

GETTING NEW MAIL

       By  now  you should have some new mail waiting.  Press the Inc button from the middle set of buttons that
       do Folder operations.  This will transfer messages from your system spool file into  your  inbox  folder.
       You  will hear an audible cue if there was new mail, and the table of contents will be updated to reflect
       the new messages in your inbox.  New messages will be underlined (on a monochrome screen), or blue (on  a
       color screen), to indicate that you have not read them yet.

       To  view  the  new  message,  click on its line in the table of contents, or press the Next button in the
       bottom group of buttons.  The message will be displayed in the bottom subwindow,  and  the  line  in  the
       table of contents will be highlighted to remind you which message is being displayed.

       To view the next message, click the Next button.  The keyboard shortcut for this is the 'n' key.

       The view the previous message, click the Prev button.  The keyboard shortcut for this is the 'p' key.

       Scrolling  through  messages.  If you get a message that is too long to fit into the message window, then
       the scrollbar will change its appearance to indicate how much text is displayed.  The scrollbar is Motif-
       like.  You can click on the arrows at either end to go up and down one line.  If you click above or below
       the elevator box you go up and down one page.  You can drag the elevator box to scroll, too.

       You can also scroll text windows in exmh by dragging with the middle  mouse  button.   Press  the  middle
       button  over  the text area, not the scrollbar, and hold it down while you move the mouse up or down.  If
       you hold the shift key at the same time, the scrolling is faster.  This works  in  the  folder  Table  of
       Contents window, too.

       Hint.   The  space  bar is a keyboard short-cut that does a combination of scrolling and advancing to the
       next message.  If the message is long, then space will scroll by one screen.  Once you are at the end  of
       the  message,  space  will advance to the next message, just like the 'n' key.  You can use the BackSpace
       key to scroll back through a message.

READING MIME MESSAGES

       By now you should have also received the sample MIME  message  from  mh-mime-sample@online.ora.com.   The
       MIME message has three parts to it, and these are numbered and labeled in the display.  The first part is
       a multipart/alternative content, which means there are a few different ways to view the content.  This is
       indicated  by the message under the heading 1. that there are alternative views of the following content.
       Exmh will go ahead and display what it thinks is the best alternative,  and  you  see  the  text/enriched
       content  displayed  in part 1.2.  If you want to see the other alternatives, then you can press the right
       button over section 1 to get a popup menu with some choices.

       The next two parts are an audio clip and a picture in GIF format.  The audio clip is handled directly  by
       exmh, and it displays two active text buttons labeled "Play attached audio" and "Save audio file".  Click
       on either of these with the left mouse button.  The part corresponding to the image  displays  a  message
       about  what  the  type is, and suggests that you press the right mouse button to display a menu.  You can
       always press the right button to get a MIME menu  that  has  type-specific  options  for  parts  of  your
       message.   If  you press the right button over part 2., then the popup menu will offer you these choices:
       Decode part as MIME Save Hello from the author...  View using mailcap rule...  Pass an audio fragment  to
       metamail...   The  first  item is a checkbox menu item that lets you view the raw content if you want to.
       The Save... menu entry displays a file selection box so you can choose a non-temporary file to store  the
       content.   This  same  function  is  available  through  the text button, but not all MIME parts displays
       buttons like this.  The next two entries  should  result  in  the  same  thing.   They  use  the  mailcap
       specifications  to  run another program that displays the content.  In the first case, View using mailcap
       rule..., exmh runs the program directly.  In the other case, Pass to metamail..., the metamail program is
       run first, and it decodes the mailcap file and runs the external program.  Again, the text button labeled
       "Play attached audio" also plays the audio.

REPLYING TO MAIL

       Select one of the messages from your friend that you'd like to answer.  Press the left  button  over  the
       Reply...  menu  button.   A  menu  with a few entries will be displayed.  Select the Reply to sender menu
       entry by dragging the mouse down to that entry and letting up over it.  The menu entry has a  <Key-r>  in
       it, which means that you could also press the 'r' key to invoke this function.

       This  time  the  built-in  editor  will  open  a window with a message that is partly filled in.  All the
       headers are initialized based on the header components from the original message.   The  built-in  editor
       will  automatically  position  the cursor at the beginning of the message body.  You can enter your reply
       message like you did with the previous messages.  You should also double-check the header components.  In
       this  case,  add yourself to the Cc: component so you will get a copy of the reply message.  When you are
       done, press the Send button in the editor window to send the message.

       There are a number of ways to control the format of your reply messages.  The MH repl command has several
       formatting  options, and because exmh uses repl to set up the reply message, you can customize your reply
       format.  Exmh lets you define several variations on reply and add them to the  Reply...  menu.   This  is
       described in the exmh-custom man page.

       It  should not take long for you to get the copy of the reply message.  Wait a minute or so and press the
       Inc button.  The keyboard short-cut for Inc is the 'i' key.

SELECTING MESSAGES

       Before we go on to more things you can do with  messages,  we  need  to  talk  about  selecting  multiple
       messages  at  once.  Several of the message operations in exmh can operate on a set of messages.  You can
       manually select multiple messages by using the mouse, or you can select messages based on their content.

       Using the Mouse.  To select messages with the mouse, press the left button and then drag out a selection.
       This  will  select  a contiguous range of messages.  If the messages you want to select are not so nicely
       organized, you can make a disjoint selection by holding down the Shift key while making  your  selection.
       This  adds new messages to the selection.  If you shift-click on a message that is already selected, then
       it becomes unselected.  If you need to select a lot of messages, simply drag the mouse  off  the  top  or
       bottom of the window.  It will be scrolled automatically and the selection will be extended.

SEARCHING

       The  Search... menu has several operations for finding messages and finding text within a message.  There
       is also a help entry that explains searching in more detail.

       If you select "Find in message body" or "Find in table of contents" a small search dialog appears.  Enter
       the  search  string and use the Next or Prev buttons to find the next match.  When you are searching over
       the table of contents, you can select All to select all matching messages.

       The other way to search a folder is with "Pick by attributes".  The MH pick program is used to search the
       current  folder  for  messages  that  match  mail headers like From or Subject.  You can build up boolean
       expressions among search criteria.  This is a much more general search mechanism than the "Find in  table
       of contents" operation.

       Get started in the Pick dialog by pressing the "Choose pick attribute" button.  A menu of attribute types
       appears, including the Subject, From, To, and Cc header components.  You can type  a  regular  expression
       pattern in these entries to search for messages that have a matching header component.

       The  Before  and  After  attributes are dates.  You can find all messages before or after a given date by
       using these fields.  You can specify dates as mm/dd/yy.  Be sure to include the year.  Dates can also  be
       keywords like "today", "yesterday", "tomorrow", and any day of the week ("Sunday", "Monday", and so on.)

       The  Search  attribute  is  used  to search for something in the body of a message.  This will run little
       slower because pick must read through all of your messages, not just their headers.

       If you select more than one attribute, pick finds messages that match all the criteria.  In other  words,
       it does the logical and of the search criteria.  If you want to search for this or that, then you need to
       press the Or button in the dialog.  This adds another set of fields to the dialog, and pick  will  search
       for everything that matches the first set or matches the second set.

       The  "Add  to  Sel" checkbutton should be set before you do the search.  This controls whether or not the
       selected messages are added to any existing selection.

       Finally, use the "Pick" button to do the search.  Once the search has completed you  can  perform  a  few
       operations  on  the  selection.   You  can  delete  and refile messages as described later.  You can also
       display a new table of contents that only contains the selected messages.  Use the "New FTOC" button  for
       this.  You can also clear the unseen state of the messages with the "Mark Seen" button.

       The "Clear" button resets the fields.

       The  two  entries in the dialog are used to control MH sequences.  The only sequence exmh really supports
       well is the "unseen" sequence, although you can define up to 10 sequences in each folder.

       If you use New FTOC to get a new scan listing, it would be better if it appeared in  a  new  window,  but
       currently  it  replaces the table of contents.  You can move around and manipulate messages in this table
       of contents.  However, if you do another pick, it  will  only  find  things  in  this  limited  table  of
       contents,  not  the  whole folder.  (Yes, this is a bug.)  Use the Rescan Folder menu entry in the folder
       More... menu to get a complete folder listing.

FORWARDING MESSAGES

       If you want to send someone a copy of a message or messages that  you  have  received,  use  the  Forward
       message  operation.   Select  the  messages  as described in the previous section, then press the Forward
       button.  The keyboard short-cut for forward is the 'f' key.

       The message template will have a copy of the selected messages.  You fill in the  headers,  and  you  can
       also  add  a  short message before the start of the forwarded messages.  When you are done, press Send to
       forward the messages.

DELETING MESSAGES

       After you have read a message, you might want to remove it to keep your mail folders tidy.  Exmh uses two
       steps  to  remove  mail.   In the first step you mark a message as being deleted.  In the second step you
       commit the operations on all marked messages.  It turns out that delete just renames your message  files.
       They will survive until you get another message by the same number and remove it, too.  In addition, exmh
       has a "Purge Folder" operation that removes these renamed files if they are more than a week old.

       The Delete operation applies to the current message, or you can  also  select  a  range  of  messages  by
       dragging out a selection in the table of contents.  You can delete the current message(s) by pressing the
       Delete button.  The keyboard short-cut is the 'd' key.  The deleted message(s) will be highlighted  after
       the  delete  operation  so  you can easily see the state of the message.  On a monochrome screen, a cross
       hatching will be drawn through the table of contents line for the message.  On a color screen, the  table
       of contents line will get a dark grey background.

       After  you  mark a message for delete, you are automatically advanced to the next message.  This makes it
       easy to go through your folder and clean it up.  Click 'd' to delete, or click 'n' to leave it alone.

       Hint.  If you are really in a hurry, use 'D' and 'N' as your keyboard short-cuts.  This prevents the next
       message from being displayed, which can be slow for complex multi-media messages.

       When  you are ready to commit the pending delete actions, press the Commit button.  The keyboard shortcut
       for commit is <Control-Return>.

       If you decide you do not want to delete a message you can unmark it.  Use the Unmark  (Undo)  menu  entry
       that is under the message More... menu.  The unmark operation applies to the current message or messages,
       so you have to select the messages to unmark first.  The keyboard short-cut for unmark is 'u'.

       Hint.  The minus, '-', keyboard shortcut takes you to the previous message, even if it  has  been  marked
       for delete.  Ordinarily the Prev operation, and the 'p' short-cut for it, will skip over marked messages.

LEAVING EXMH

       Press  the  Quit  button  to  leave exmh.  It will take a few moments to close down because it saves some
       state information before quitting.  The Quit button will grey out after you click it, and you will see  a
       few status messages as it shuts itself down.

PREFERENCES

       Try  out  the Preferences by turning off the folder cache.  This just takes up display space if you don't
       have many folders.  If you have lots of nested folders, though, you might even want to make this  display
       bigger!

       Click  the  Preference  button, which brings up a dialog that has buttons for several of the modules that
       make up exmh.  Click on the Folder Cache button to bring up the preference items that control the  folder
       cache.   In this case there are just two items: the number of lines of labels in the cache, and the names
       of folders that are always in the cache.  Click in the first field and backspace over the  default  value
       of 1.  Type in 0 instead, and press <Return>.  Voila!  The folder cache disappears.

       If  you  like  this setting, press Save on the main Preference dialog and your changes will be saved to a
       file named ~/.exmh-defaults.  Press Reset if you want to undo your  changes.   You  should  be  a  little
       careful here, because you are allowed to Dismiss the preference dialog without saving.

       Another  useful  preference  item  to  set  is  under Background Processing.  You can arrange for exmh to
       periodically run inc so your messages are automatically transferred into your inbox.   The  advantage  of
       doing  this is that the folder label highlighting works best this way.  Unfortunately, exmh does not give
       you any visual clues when mail is only waiting in your system spool file.

       More details about the Preferences dialog are given in the exmh-use man page,  and  an  overview  of  the
       various preference sections is given in the exmh-custom man page..

WHAT IS MH MAIL?

       MH  is  a  collection  of UNIX programs that store, manipulate, and display your mail. MH originated from
       RAND, and it is now in the public domain.  Exmh uses these programs to do all the  hard  work,  while  it
       concentrates on the user interface.

       You  can  use  the MH programs to read your mail.  Run them from the UNIX command line like you would cd,
       ls, cc, or make.  They are useful when you are connecting over a slow line or cannot run  exmh  for  some
       other  reason.   For  more details, there are individual man pages for each MH program, plus one overview
       man page called MH.  Below is a short summary of the main MH programs used by exmh.

       folder Query or set the current folder.

       inc    Incorporate mail from your system spool file into your folders.

       scan   Display a listing of a mail folder.

       show   Display a mail message.

       next   Display the next mail message.  (Exmh doesn't actually run this.)

       prev   Display the previous mail message.  (Exmh doesn't actually run this.)

       rmm    Delete a mail message.

       refile Move a message into another mail folder.

       repl   Reply to a mail message

       forw   Forward one or more mail messages.

       comp   Compose a new mail message.

       MH keeps track of the current folder and the current message in between uses of these MH  programs.   For
       example:  %  scan  +inbox  unseen  1713   04/14  foote.PARC@xerox.   Have  you  started  blasting  cdroms

       Each user has a .mh_profile file that stores general MH settings as well as per-command  settings.   Each
       line  has a key, and a value.  For example, your mail directory is set with the Path profile entry: Path:
       Mail

       If your old mail system uses that directory already, just edit your .mh_profile to change the  name  used
       for your MH mail folders.

MORE ABOUT EXMH

       This  man  page should get you started with exmh.  If you decide you want to know more about it, here are
       some of the features described in the other exmh man pages.

       MIME support.  Exmh can display MIME (Multipurpose Internet Mail Extensions) messages, either directly or
       with  the  help of the metamail package.  The built-in editor lets you compose enriched text messages and
       insert files as parts of a multipart message.

       Mail Folders.  You can create other mail folders to hold messages about certain topics  or  from  certain
       people.   You  can  create  a  hierarchical  arrangement of folders, just like the hierarchical directory
       structure of the file system.  The folder display supports these nested folders, and  it  allows  you  to
       nest folders to any depth.

       Mail Filtering.  Mail filtering lets you sort mail into different folders before you read it.  If you get
       lots of mail, this is a great way to avoid plowing through junk mail just to get your important messages.
       The folder labels are highlighted to indicate which folders have unread mail in them.

       Facesaver bitmap display.  If you have a facesaver database on your system, exmh displays the bitmap face
       of the person that sent the current message (or their organization).

       Background processing.  You can set exmh to  run  inc  periodically,  check  for  new  messages  arriving
       asynchronously in folders, run the MH msgchk program, or count up the messages in your mail spool file.

       Editor  interface.  You can hook exmh to your favorite editor using the exmh-async script.  Or, Tcl-based
       editors such as mxedit can interact with exmh directly.

       Keybinding User Interface.  You can define new key bindings  for  Tcl  commands  that  are  part  of  the
       implementation.

       Aliases  User  Interface.   A  browser for your MH aliases lets you define new aliases and insert aliases
       into mail messages.

       Pretty Good Privacy (PGP).  If you have PGP, you can use it from exmh to  digitally  sign,  encrypt,  and
       decrypt messages.

       User Programming.  If the preference settings are not enough for you, you can program exmh more directly.
       You can define new buttons and menus and add new Tcl code to its implementation.
