Emacs无法重设Ctrl-d键的行为 [英] Emacs can't reset Ctrl-d key behaviour

问题描述

我想改变 Ctrl - d 键的行为。所以它会删除一个字向后。我创建了一个函数：

I wanted to change the behaviour of Ctrl-d key. So it will delete a word backward. I created a function:

(defun backward-delete-word (arg)
      "Delete characters backward until encountering the beginning of a word.
With argument ARG, do this that many times."
      (interactive "p")
      (delete-region (point) (progn (backward-word arg) (point))))

然后将其插入 emacs.d ：

(global-set-key (kbd "\C-d") 'backward-delete-word)

它以基本模式工作，但在php模式下，它只会删除下一个字符。当我点击

It works in fundamental-mode, but in php-mode it just removes the next character. When I click

Ctrl-h k Ctrl-d

Ctrl-h k Ctrl-d

Emacs给出：

C-d runs the command c-electric-delete-forward, which is an
interactive compiled Lisp function in `cc-cmds.el'.

It is bound to C-d.

(c-electric-delete-forward ARG)

不知何故被重置为另一个功能。如何找出它在哪里重新设置并使其与我的功能一起工作？

Somehow, it was reset to another function. How to find out, where it was reset and make it work with my function instead?

推荐答案

我没有code> php-mode 所以我不能肯定地说，但绑定可能会覆盖在 php-mode-map （其中，作为主要模式地图，优先级高于全球地图）。

I don't have php-mode so I can't say for sure, but the binding is likely overriden in php-mode-map (which, as a major mode map, has higher precedence than the global map).

您可以使用 Ch b 来检查列出所有可用的密钥绑定并在输出缓冲区中查找 Cd 或 c-electric-delete-forward ，以查看哪个键盘映射绑定被定义。

You can check by using C-h b to list all available key bindings and look for C-d or c-electric-delete-forward in the output buffer to see in which keymap the binding is defined.

假设 php-mode-map 覆盖 Cd 绑定，你可以使用

Assuming php-mode-map overrides the C-d binding, you can disable it using

(define-key php-mode-map (kbd "C-d") nil)
