Emacs：用于命令的打印键绑定或列出所有键绑定 [英] Emacs: print key binding for a command or list all key bindings

问题描述

在Emacs（GNU 23.2，* nix）中，我如何：

In Emacs (GNU 23.2, *nix), how can I:

1. 列出绑定到特定命令的键序列？例如，我们如何列出执行 save-buffers-kill-emacs 的所有键序列，键序列的输出与它绑定？假设我们可以这样做，列出绑定到 goto-line 的关键序列应该打印输出： Mg g 默认安装。


2. 列出所有键绑定？是否执行 C-h b 是否打印自己的绑定？

1. list the key sequences bound to a particular command? For example, how can we list all the key sequences that execute save-buffers-kill-emacs, with the output of key sequences bound to it? Assuming we can do this, listing the key sequences bound to goto-line should print the output: M-g g on a default install.
2. list all key-bindings? Does C-h b do this? Would it print my own bindings?

我知道直接执行命令可以打印可以激活的键序列，但是它并不总是这样做，并且发生一些事情，包括：

（1）输出不会持续很长时间，（2）执行命令。

I am aware that executing the command directly can print a key sequence it can be activated with, but it doesn't always do so, and a few things happen, including:
(1) the output doesn't remain for long, (2) the command is executed.

我想要一个命令，它为我列出（最好是所有）附加到给定命令的绑定，而不执行命令，或类似的东西。

I want a command that lists for me (preferably all) the bindings attached to a given command, without executing the command, or something like that.

推荐答案

1. Chf （或 Mx describe-function < kbd>）将显示一个命令的绑定。

1. C-h f (or M-x describe-function) will show you the bindings for a command.

你是正确的， Ch b （或 Mx描述-bindings ）将显示所有绑定。

You are correct, C-h b (or M-x describe-bindings) will show you all bindings. C-h m (M-x describe-mode) is also handy to list bindings by mode.

$ b $ b

您还可以尝试使用 Ch k （ Mx describe-key ）来显示什么命令绑定到一个键。例如，在我的机器上， save-buffers-kill-emacs 不限于任何东西，但是 Ch k Cx Cc 告诉我， > Cx Cc 绑定到 save-buffers-kill-terminal 。它将同时列出该命令的所有绑定。

You might also try C-h k (M-x describe-key) to show what command is bound to a key. For instance, on my machine save-buffers-kill-emacs isn't bound to anything, but C-h k C-x C-c tells me that C-x C-c is bound to save-buffers-kill-terminal. It will list all bindings for the command at the same time.
