Added (private) function `notmuch--prefix-bindings' which wraps `describe-prefix-bindings' to provide more suitable user interface for showing the key sequences that follow a particular notmuch prefix keymap invocation. The key '?' in prefix keymaps `notmuch-search-stash-map', `notmuch-show-stash-map' and `notmuch-show-part-map' is bound to this function via `lambda' expression. By using this lambda expression the pop-up binding description window shows '??' instead of `notmuch--prefix-bindings' for the binding of '?' -- which suits our needs perfectly. --- emacs/notmuch-lib.el | 9 +++++++++ emacs/notmuch-show.el | 2 ++ emacs/notmuch.el | 1 + 3 files changed, 12 insertions(+) diff --git a/emacs/notmuch-lib.el b/emacs/notmuch-lib.el index 4796f17..8191aec 100644 --- a/emacs/notmuch-lib.el +++ b/emacs/notmuch-lib.el @@ -553,6 +553,15 @@ status."
