重新定义emacs中的主要模式前缀键

Question

我一直在尝试自学野蛮人，因为我正在使用dvorak，所以我愚蠢地反弹 C-c 到运动键并习惯了它。现在，我实际上开始使用它进行一些编程，然后我加载了一个Python文件，并注意到 C-c 是所有特殊命令的前缀 python-mode.

我可以重新启动前缀键，然后在我的一个swoop中更改所有python命令 init.el 文件？如果没有，我应该单独重新启动所有python命令吗？

如果您查看python.el的源代码，您会发现使用完整规范单独添加命令，例如 (define-key map "\C-c\C-r" 'python-send-region).

因此，您将不得不自己重做。就是说这很简单。从您的评论中，您想更改前缀键 C-', ，正确逃脱的诀窍是完全不使用逃脱，而是使用宏 kbd (文档链接).

因此，您可以将模式映射定义更新为：

(defvar python-mode-map
  (let ((map (make-sparse-keymap)))
    ;; Mostly taken from python-mode.el.
    (define-key map ":" 'python-electric-colon)
    (define-key map "\177" 'python-backspace)

Answer 2

如果你想 Ctrl+C 充当 left 和 F12 充当 C-c:

(define-key key-translation-map [f12] "\C-c")
(define-key key-translation-map "\C-c" [left])

请注意，这也会影响多键绑定，例如您现在需要键入 Ctrl+X F12 退出Emacs。这枚硬币的另一面是 C-c C-c 键入为 F12 F12.
