| 29 | ;;; Commentary: |
| 30 | |
| 31 | ;; How to Use: |
| 32 | ;; M-x mh-rmail to read mail. Type C-h m there for a list of commands. |
| 33 | ;; C-u M-x mh-rmail to visit any folder. |
| 34 | ;; M-x mh-smail to send mail. From within the mail reader, "m" works, too. |
| 35 | |
| 36 | ;; Your .emacs might benefit from these bindings: |
| 37 | ;; (global-set-key "\C-cr" 'mh-rmail) |
| 38 | ;; (global-set-key "\C-xm" 'mh-smail) |
| 39 | ;; (global-set-key "\C-x4m" 'mh-smail-other-window) |
| 40 | |
| 41 | ;; MH (Message Handler) is a powerful mail reader. |
| 42 | |
| 43 | ;; The MH newsgroup is comp.mail.mh; the mailing list is mh-users@ics.uci.edu |
| 44 | ;; (send to mh-users-request to be added). See the monthly Frequently Asked |
| 45 | ;; Questions posting there for information on getting MH and MH-E: |
| 46 | ;; http://www.faqs.org/faqs/mail/mh-faq/part1/preamble.html |
| 47 | |
| 48 | ;; N.B. MH must have been compiled with the MHE compiler flag or several |
| 49 | ;; features necessary for MH-E will be missing from MH commands, specifically |
| 50 | ;; the -build switch to repl and forw. |
| 51 | |
| 52 | ;; MH-E is an Emacs interface to the MH mail system. |
| 53 | |
| 54 | ;; MH-E is supported in GNU Emacs 21 and 22 as well as XEmacs 21 |
| 55 | ;; (except for versions 21.5.9-21.5.16), with MH 6.8.4 on, nmh 1.0.4 |
| 56 | ;; on, and GNU mailutils 0.4 on. |
| 57 | |

| 79 | ;; Original version for Gosling emacs by Brian Reid, Stanford, 1982. |
| 80 | ;; Modified by James Larus, BBN, July 1984 and UCB, 1984 & 1985. |
| 81 | ;; Rewritten for GNU Emacs, James Larus, 1985. |
| 82 | ;; Modified by Stephen Gildea, 1988. |
| 83 | ;; Maintenance picked up by Bill Wohler and the |
| 84 | ;; SourceForge Crew <http://mh-e.sourceforge.net/>, 2001. |

| 1791 | Ranges |
| 1792 | ====== |
| 1793 | Many commands that operate on individual messages, such as |
| 1794 | `mh-forward' or `mh-refile-msg' take a RANGE argument. This argument |
| 1795 | can be used in several ways. |
| 1796 | |
| 1797 | If you provide the prefix argument (\\[universal-argument]) to |
| 1798 | these commands, then you will be prompted for the message range. |
| 1799 | This can be any valid MH range which can include messages, |
| 1800 | sequences, and the abbreviations (described in the mh(1) man |
| 1801 | page): |
| 1802 | |
| 1803 | <num1>-<num2> |
| 1804 | Indicates all messages in the range <num1> to <num2>, inclusive. |
| 1805 | The range must be nonempty. |
| 1806 | |
| 1807 | <num>:N |
| 1808 | <num>:+N |
| 1809 | <num>:-N |
| 1810 | Up to N messages beginning with (or ending with) message num. Num |
| 1811 | may be any of the predefined symbols: first, prev, cur, next or |
| 1812 | last. |
| 1813 | |
| 1814 | first:N |
| 1815 | prev:N |
| 1816 | next:N |
| 1817 | last:N |
| 1818 | The first, previous, next or last messages, if they exist. |
| 1819 | |
| 1820 | all |
| 1821 | All of the messages. |
| 1822 | |
| 1823 | For example, a range that shows all of these things is `1 2 3 |
| 1824 | 5-10 last:5 unseen'. |
| 1825 | |
| 1826 | If the option `transient-mark-mode' is set to t and you set a |
| 1827 | region in the MH-Folder buffer, then the MH-E command will |
| 1828 | perform the operation on all messages in that region. |
