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. | |

36 | ;; Your .emacs might benefit from these bindings: |
37 | ;; (global-set-key "\C-cr" 'mh-rmail) | |
38 | ;; (global-set-key "\C-xm" 'mh-smail) | |

1525 | Ranges |
1526 | ====== | |
1527 | Many commands that operate on individual messages, such as `mh-forward' or | |
1528 | `mh-refile-msg' take a RANGE argument. This argument can be used in several | |
1529 | ways. | |
1530 | ||
1531 | If you provide the prefix argument (\\[universal-argument]) to these commands, | |
88a34f43 | 1532 | then you will be prompted for the message range. This can be any valid MH |
f0d73c14 BW |
1533 | range which can include messages, sequences, and the abbreviations (described |
1534 | in the mh(1) man page): | |
1535 | ||
1536 | <num1>-<num2> | |
1537 | Indicates all messages in the range <num1> to <num2>, inclusive. The range | |
1538 | must be nonempty. | |
1539 | ||
1540 | `<num>:N' | |
1541 | `<num>:+N' | |
1542 | `<num>:-N' | |
1543 | Up to N messages beginning with (or ending with) message num. Num may be | |
1544 | any of the pre-defined symbols: first, prev, cur, next or last. | |
1545 | ||
1546 | `first:N' | |
1547 | `prev:N' | |
1548 | `next:N' | |
1549 | `last:N' | |
1550 | The first, previous, next or last messages, if they exist. | |
1551 | ||
1552 | `all' | |
1553 | All of the messages. | |
1554 | ||
1555 | For example, a range that shows all of these things is `1 2 3 5-10 last:5 | |
1556 | unseen'. | |
1557 | ||
1558 | If the option `transient-mark-mode' is set to t and you set a region in the | |
1559 | MH-Folder buffer, then the MH-E command will perform the operation on all | |
1560 | messages in that region. | |
