问题描述
当我查询 keymap 的当前值时，例如使用 M-: (current-local-map)，它会向我显示以下内容:
值:(键盘映射(S-mouse-2 . muse-follow-name-at-mouse-other-window)(mouse-2 .muse-follow-name-at-mouse)(33554445 . 缪斯跟随姓名在点其他窗口)(S-return . muse-follow-name-at-point-other-window)(13 . 缪斯跟随姓名在点)(返回 .muse-follow-name-at-point)键盘映射(67108924 . muse-decrease-list-item-indentation)(67108926 . muse-increase-list-item-indentation)(M-return .muse-insert-list-item)(33554441 . 缪斯以前的参考)(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 . 缪斯跟随姓名在点其他窗口)(9 . 缪斯-下一个参考)(标签.缪斯下一个参考)(3 键映射(19 . 缪斯搜索)(2 . muse-find-backlinks)(标签.缪斯插入物)(9 . 缪斯插入物)(16 . 缪斯-项目-发布)(6 . muse-project-find-file)(61 . 缪斯-改变了什么)(22 . 缪斯浏览结果)(27 键映射(20 .缪斯发布此文件))(33554452 . 缪斯发布此文件)(20 . muse-project-publish-this-file)(12 . 字体锁定模式)(5 . muse-edit-link-at-point)(1 . 缪斯索引))键盘映射(27 键映射(9 . ispell-complete-word)))我希望看到更有意义的东西而不是数字，例如 (control ?c) return .我怎么做 ?
解决方案
这就是你所需要的:库 help-fns+.el.
这为您提供了 命令 describe-keymap，它为您提供了绑定到变量的任何键映射的人类可读描述.例如:
When I query the current value of the keymap, eg with M-: (current-local-map), it shows me something along these lines:
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)))
I want instead of numbers see something more meaningful like (control ?c) return for example. How do I do that ?
解决方案
This is what you need: library help-fns+.el.
That gives you, as , command describe-keymap, which gives you a human-readable description of any keymap bound to a variable. E.g.:
dired-mode-map

For more information check the manuals.
Local keymap for `dired-mode' buffers.
