;;; Commentary:
;; All commands run from the summary buffer update the buffer local
;; variable `pmail-current-message'. As part of the post command
;; processing point is moved to the beginning of the line describing
;; the current message.
;;; History:
;; Extended by Bob Weiner of Motorola
;; Provided all commands from pmail-mode in pmail-summary-mode and made key
;; bindings in both modes wholly compatible.
;; Overhauled by Paul Reilly to support mbox format.
;;; Code:

All normal editing commands are turned off.
Instead, nearly all the Pmail mode commands are available,
though many of them move only among the messages in the summary.
These additional commands exist:
\\[pmail-summary-undelete-many] Undelete all or prefix arg deleted messages.
\\[pmail-summary-wipe] Delete the summary and go to the Pmail buffer.
Commands for filtering the summary:
\\[pmail-summary-by-labels] Filter by label.
\\[pmail-summary-by-topic] Filter by Subject.
Filter by the entire message (header and body) if given a
prefix argument.
\\[pmail-summary-by-senders] Filter by From field.
\\[pmail-summary-by-recipients] Filter by To, From, and Cc fields.
Filter by To and From only if given a prefix argument.
The commands listed above take comma-separated lists of regular
expressions.
\\[pmail-summary-by-regexp] Filter by any header line.
\\[pmail-summary] Restore the default summary.
Commands for sorting the summary:
\\[pmail-summary-sort-by-date] Sort by date.
\\[pmail-summary-sort-by-subject] Sort by subject.
\\[pmail-summary-sort-by-author] Sort by author.
\\[pmail-summary-sort-by-recipient] Sort by recipient.
\\[pmail-summary-sort-by-correspondent] Sort by correspondent.
\\[pmail-summary-sort-by-lines] Sort by lines.
