552 | Ranges | |
553 | ====== | |
554 | Many commands that operate on individual messages, such as | |
555 | `mh-forward' or `mh-refile-msg' take a RANGE argument. This argument | |
556 | can be used in several ways. | |
557 | ||
558 | If you provide the prefix argument (\\[universal-argument]) to | |
559 | these commands, then you will be prompted for the message range. | |
560 | This can be any valid MH range which can include messages, | |
561 | sequences, and the abbreviations (described in the mh(1) man | |
562 | page): | |
563 | ||
564 | <num1>-<num2> | |
565 | Indicates all messages in the range <num1> to <num2>, inclusive. | |
566 | The range must be nonempty. | |
567 | ||
568 | <num>:N | |
569 | <num>:+N | |
570 | <num>:-N | |
571 | Up to N messages beginning with (or ending with) message num. Num | |
572 | may be any of the predefined symbols: first, prev, cur, next or | |
573 | last. | |
574 | ||
575 | first:N | |
576 | prev:N | |
577 | next:N | |
578 | last:N | |
579 | The first, previous, next or last messages, if they exist. | |
580 | ||
581 | all | |
582 | All of the messages. | |
583 | ||
584 | For example, a range that shows all of these things is `1 2 3 | |
585 | 5-10 last:5 unseen'. | |
586 | ||
587 | If the option `transient-mark-mode' is set to t and you set a | |
588 | region in the MH-Folder buffer, then the MH-E command will | |
589 | perform the operation on all messages in that region. | |
