emacs - 在 Emacs 键映射值中显示键

Question

当我查询键映射的当前值时，例如使用 M-: (current-local-map) ，它向我展示了以下内容:

Value: 
(keymap
 (S-mouse-2 . muse-follow-name-at-mouse-other-window)
 (mouse-2 . muse-follow-name-at-mouse)
 (33554445 . muse-follow-name-at-point-other-window)
 (S-return . muse-follow-name-at-point-other-window)
 (13 . muse-follow-name-at-point)
 (return . muse-follow-name-at-point)
 keymap
 (67108924 . muse-decrease-list-item-indentation)
 (67108926 . muse-increase-list-item-indentation)
 (M-return . muse-insert-list-item)
 (33554441 . muse-previous-reference)
 (S-iso-lefttab . muse-previous-reference)
 (S-tab . muse-previous-reference)
 (S-mouse-2 . muse-follow-name-at-mouse-other-window)
 (mouse-2 . muse-follow-name-at-mouse)
 (33554445 . muse-follow-name-at-point-other-window)
 (9 . muse-next-reference)
 (tab . muse-next-reference)
 (3 keymap
    (19 . muse-search)
    (2 . muse-find-backlinks)
    (tab . muse-insert-thing)
    (9 . muse-insert-thing)
    (16 . muse-project-publish)
    (6 . muse-project-find-file)
    (61 . muse-what-changed)
    (22 . muse-browse-result)
    (27 keymap
        (20 . muse-publish-this-file))
    (33554452 . muse-publish-this-file)
    (20 . muse-project-publish-this-file)
    (12 . font-lock-mode)
    (5 . muse-edit-link-at-point)
    (1 . muse-index))
 keymap
 (27 keymap
     (9 . ispell-complete-word)))

我希望看到的不是数字而是更有意义的东西，例如 (control ?c) return例如。我怎么做 ？

Answer 1

你知道命令 C-h m ( describe-mode )，通常显示当前主要和次要模式的描述，通常带有它们的键盘映射？

(substitute-command-keys "\\{foo-map}")是什么describe-mode内部使用以生成用户友好的键映射描述 foo-map .

如果您想要更接近键映射结构的东西，该 API 记录在 Emacs Lisp 手册的“分类事件”中。例如，(event-modifiers 33554445) ==> (shift control)(format "%c" (event-basic-type 33554445)) ==> "m"
