;;; 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.
|
||
|
||
;; 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)
|
||
|
||
;; 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:
|
||
;; http://www.faqs.org/faqs/mail/mh-faq/part1/preamble.html
|
||
|
||
;; N.B. 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.
|
||
|
||
;; MH-E is an Emacs interface to the MH mail system.
|
||
|
||
;; MH-E is supported in GNU Emacs 20 and 21, with MH 6.8.4 and nmh 1.0.4.

;;; 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.
|
||
;; Modified by Stephen Gildea, 1988.
|
||
;; Maintenance picked up by Bill Wohler and the
|
||
;; SourceForge Crew <http://mh-e.sourceforge.net/>, 2001.

Ranges
|
||
======
|
||
Many commands that operate on individual messages, such as `mh-forward' or
|
||
`mh-refile-msg' take a RANGE argument. This argument can be used in several
|
||
ways.
|
||
|
||
If you provide the prefix argument (\\[universal-argument]) to these commands,
|
||
then you will be prompted for the message range. This can be any legal MH
|
||
range which can include messages, sequences, and the abbreviations (described
|
||
in the mh(1) man page):
|
||
|
||
<num1>-<num2>
|
||
Indicates all messages in the range <num1> to <num2>, inclusive. The range
|
||
must be nonempty.
|
||
|
||
`<num>:N'
|
||
`<num>:+N'
|
||
`<num>:-N'
|
||
Up to N messages beginning with (or ending with) message num. Num may be
|
||
any of the pre-defined symbols: first, prev, cur, next or last.
|
||
|
||
`first:N'
|
||
`prev:N'
|
||
`next:N'
|
||
`last:N'
|
||
The first, previous, next or last messages, if they exist.
|
||
|
||
`all'
|
||
All of the messages.
|
||
|
||
For example, a range that shows all of these things is `1 2 3 5-10 last:5
|
||
unseen'.
|
||
|
||
If the option `transient-mark-mode' is set to t and you set a region in the
|
||
MH-Folder buffer, then the MH-E command will perform the operation on all
|
||
messages in that region.
