From 26d5b0efe4160b789670fbb059bea4630a352212 Mon Sep 17 00:00:00 2001 From: Dmitry Kurochkin Date: Sun, 5 Feb 2012 11:13:48 +0400 Subject: [PATCH] emacs: add "*" binding for notmuch-show view The patch adds `notmuch-show-tag-all' function bound to "*" in notmuch-show view. The function is similar to the `notmuch-search-tag-all' function for the notmuch-search view: it changes tags for all messages in the current thread. --- emacs/notmuch-show.el | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el index 48a2a60f..faa9f9b4 100644 --- a/emacs/notmuch-show.el +++ b/emacs/notmuch-show.el @@ -1084,6 +1084,7 @@ thread id.
