548 You can show the message the cursor is pointing to, and step through
549 the messages. Messages can be marked for deletion or refiling into
550 another folder; these commands are executed all at once with a
551 separate command.
553 Options that control this mode can be changed with
555 see the `mh-scan-format-file' option if you wish to modify scan's
556 format.
558 When a folder is visited, the hook `mh-folder-mode-hook' is run.
560 Ranges
561 ======
562 Many commands that operate on individual messages, such as
563 `mh-forward' or `mh-refile-msg' take a RANGE argument. This argument
564 can be used in several ways.
567 these commands, then you will be prompted for the message range.
568 This can be any valid MH range which can include messages,
569 sequences, and the abbreviations (described in the mh(1) man
570 page):
572 <num1>-<num2>
573 Indicates all messages in the range <num1> to <num2>, inclusive.
574 The range must be nonempty.
576 <num>:N
577 <num>:+N
578 <num>:-N
579 Up to N messages beginning with (or ending with) message num. Num
580 may be any of the predefined symbols: first, prev, cur, next or
581 last.
583 first:N
584 prev:N
585 next:N
586 last:N
587 The first, previous, next or last messages, if they exist.
589 all
590 All of the messages.
592 For example, a range that shows all of these things is `1 2 3
593 5-10 last:5 unseen'.
595 If the option `transient-mark-mode' is set to t and you set a
596 region in the MH-Folder buffer, then the MH-E command will
597 perform the operation on all messages in that region.
