`notmuch-hello-mode' inherits the keymap for widgets, which confused `notmuch-substitute-command-keys'. Fix the confusion. Simplify `notmuch-substitute-command-keys' a little to make it easier to read.

|
|
; This is an emacs-based interface to the notmuch mail system.
|
|
;
|
|
; You will first need to have the notmuch program installed and have a
|
|
; notmuch database built in order to use this. See
|
|
; http://notmuchmail.org for details.
|
|
;
|
|
; To install this software, copy it to a directory that is on the
|
|
; `load-path' variable within emacs (a good candidate is
|
|
; /usr/local/share/emacs/site-lisp). If you are viewing this from the
|
|
; notmuch source distribution then you can simply run:
|
|
;
|
|
; sudo make install-emacs
|
|
;
|
|
; to install it.
|
|
;
|
|
; Then, to actually run it, add:
|
|
;
|
|
; (require 'notmuch)
|
|
;
|
|
; to your ~/.emacs file, and then run "M-x notmuch" from within emacs,
|
|
; or run:
|
|
;
|
|
; emacs -f notmuch
|
|
;
|

This buffer contains the results of a \"notmuch search\" of your
|
|
email archives. Each line in the buffer represents a single
|
|
thread giving a summary of the thread (a relative date, the
|
|
number of matched messages and total messages in the thread,
|
|
participants in the thread, a representative subject line, and
|
|
any tags).
|

Pressing \\[notmuch-search-show-thread] on any line displays that thread. The '\\[notmuch-search-add-tag]' and '\\[notmuch-search-remove-tag]'
|
|
keys can be used to add or remove tags from a thread. The '\\[notmuch-search-archive-thread]' key
|
|
is a convenience for archiving a thread (removing the \"inbox\"
|
|
tag). The '\\[notmuch-search-operate-all]' key can be used to add or remove a tag from all
|
|
threads in the current buffer.
|
|
|
|
Other useful commands are '\\[notmuch-search-filter]' for filtering the current search
|
|
based on an additional query string, '\\[notmuch-search-filter-by-tag]' for filtering to include
|
|
only messages with a given tag, and '\\[notmuch-search]' to execute a new, global

search.
