Emacs可以区分ctrl-r和ctrl-shift-r吗？ [英] Can Emacs differentiate between ctrl-r and ctrl-shift-r?

问题描述

我想将 Ctrl + R 绑定到'isearch-backward 并绑定 Ctrl + Shift + R 到'tags-apropos 但是我无法区分两个键

可以emacs区分 Ctrl + R 和 Ctrl + Shift + R ？什么应该进入我的.emacs文件以允许这个键盘绑定？

解决方案

是的。

pre> （global-set-key（kbdCr）'isearch-backward）
（global-set-key（kbdCSr）' apropos）


找出这种问题的答案的方法是在键上做一个帮助 Ch k ，并键入您感兴趣的按键。Emacs在帮助缓冲区中显示的是您可以传递给宏的字符串 kbd 。

I'd like to bind Ctrl + R to 'isearch-backward and bind Ctrl + Shift + R to 'tags-apropos but I can't distinguish between the two key presses.

Can emacs differentiate between Ctrl + R and Ctrl + Shift + R? What should go into my .emacs file to allow this keybinding?

解决方案

Yes.

(global-set-key (kbd "C-r") 'isearch-backward)
(global-set-key (kbd "C-S-r") 'tags-apropos)

The way to figure out the answer to this kind of question is to do help on a key C-h k, and type the keystrokes you're interested in. What Emacs shows in the Help buffer is the string you can pass to the macro 'kbd.
