|
||
;;; Commentary:
|
||
|
||
;; HOW TO USE:
|
||
;; M-x mh-rmail to read mail. Type C-h m there for a list of commands.
|
||
;; C-u M-x mh-rmail to visit any folder.
|
||
;; M-x mh-smail to send mail. From within the mail reader, "m" works, too.
|
||
|
||
;; MH (Message Handler) is a powerful mail reader. The MH newsgroup
|
||
;; is comp.mail.mh; the mailing list is mh-users@ics.uci.edu (send to
|
||
;; mh-users-request to be added). See the monthly Frequently Asked
|
||
;; Questions posting there for information on getting MH and mh-e.
|
||
|
||
;; mh-e is an Emacs interface to the MH mail system.
|
||
;; There is a mailing list for discussion of mh-e and
|
||
;; announcements of new versions. Send a "subscribe" message to
|
||
;; mh-e-request@gnu.org to be added. Do not report bugs here; mail
|
||
;; them directly to the maintainer (see top of mh-e.el source).
|
||
;; Include the output of M-x mh-version in any bug report.
|
||
|
||
;; mh-e works with GNU Emacs 18 or 19, and MH 6.
|
||
|
||
;; NB. MH must have been compiled with the MHE compiler flag or several
|
||
;; features necessary for mh-e will be missing from MH commands, specifically
|
||
;; the -build switch to repl and forw.
|
||
|
||
;; Your .emacs might benefit from these bindings:
|
||
;; (global-set-key "\C-cr" 'mh-rmail)
|
||
;; (global-set-key "\C-xm" 'mh-smail)
|
||
;; (global-set-key "\C-x4m" 'mh-smail-other-window)
|
||
|
||
;;; Change Log:
|
||
|
||
;; Original version for Gosling emacs by Brian Reid, Stanford, 1982.
|
||
;; Modified by James Larus, BBN, July 1984 and UCB, 1984 & 1985.
|
||
;; Rewritten for GNU Emacs, James Larus 1985. larus@ginger.berkeley.edu
|
||
;; Modified by Stephen Gildea 1988. gildea@lcs.mit.edu

You can show the message the cursor is pointing to, and step through the

messages. Messages can be marked for deletion or refiling into another
|

folder; these commands are executed all at once with a separate command.
|
||
|

A prefix argument (\\[universal-argument]) to delete, refile, list, or undo
|
||
applies the action to a message sequence.
|
||
|
||
Here is a list of the standard keys for mh-e commands, grouped by function.
|
||
This list is purposefully not customized; mh-e has a long history, and many
|
||
alternate key bindings as a result. This list is to encourage users to use
|
||
standard keys so the other keys can perhaps someday be put to new uses.
|
||
|
||
t toggle show or scan-only mode
|
||
RET show message, or back to top if already showing
|
||
|
||
SPC page message forward
|
||
DEL page message back
|
||
|
||
n next message
|
||
p previous message
|
||
g go to message by number
|
||
|
||
d mark for deletion
|
||
o, ^ mark for output (refile) to another folder
|
||
? show folder of pending refile
|
||
u undo delete or refile marking
|
||
|
||
x execute marked deletes and refiles
|
||
i incorporate new mail
|
||
|
||
m mail a new message
|
||
r reply to a message
|
||
f forward a message
|
||
|
||
q quit mh-e
|
||
|
||
M-f visit new folder
|
||
M-r rescan this folder
|

|
||
Here are all the commands with their current binding, listed in key order:
|
||
\\{mh-folder-mode-map}
|
||
|
||
Variables controlling mh-e operation are (defaults in parentheses):
|
||
|
||
mh-recursive-folders (nil)
|
||
Non-nil means commands which operate on folders do so recursively.
|
||
|
||
mh-bury-show-buffer (t)
|
||
Non-nil means that the buffer used to display message is buried.
|
||
It will never be offered as the default other buffer.
|
||
|
||
mh-clean-message-header (nil)
|
||
Non-nil means remove header lines matching the regular expression
|
||
specified in mh-invisible-headers from messages.
|
||
|
||
mh-visible-headers (nil)
|
||
If non-nil, it contains a regexp specifying the headers that are shown in
|
||
a message if mh-clean-message-header is non-nil. Setting this variable
|
||
overrides mh-invisible-headers.
|
||
|
||
mh-do-not-confirm (nil)
|
||
Non-nil means do not prompt for confirmation before executing some
|
||
non-recoverable commands such as mh-kill-folder and mh-undo-folder.
|
||
|
||
mhl-formfile (nil)
|
||
Name of format file to be used by mhl to show messages.
|
||
A value of T means use the default format file.
|
||
Nil means don't use mhl to format messages.
|
||
|
||
mh-lpr-command-format (\"lpr -p -J '%s'\")
|
||
Format for command used to print a message on a system printer.
|
||
|
||
mh-scan-prog (\"scan\")
|
||
Program to run to generate one-line-per-message listing of a folder.
|
||
Normally \"scan\" or a file name linked to scan. This file is searched
|
||
for relative to the mh-progs directory unless it is an absolute pathname.
|
||
Automatically becomes buffer-local when set in any fashion.
|
||
|
||
mh-print-background (nil)
|
||
Print messages in the background if non-nil.
|
||
WARNING: do not delete the messages until printing is finished;
|
||
otherwise, your output may be truncated.
|
||
|
||
mh-recenter-summary-p (nil)
|
||
If non-nil, then the scan listing is recentered when the window displaying
|
||
a messages is toggled off.
|
||
|
||
mh-summary-height (4)
|
||
Number of lines in the summary window including the mode line.
