emacs - [控制上移] 不起作用

发布于 2024-10-11 00:09:05 字数 620 浏览 6 评论 0原文

我尝试将热键定义如下，

(global-set-key [(control shift up)] 'other-window)

但它不起作用（没有错误，只是不起作用），

(global-set-key [(control shift down)] 'other-window)

但是

(global-set-key [(control shift right)] 'other-window)

和也

(global-set-key [(control shift left)] 'other-window)

不起作用！

但因为最后两个组合键由 emacs 使用（默认），我不想将它们更改为其他功能。

那么我怎样才能使 control-shift-up 和 control-shift-down 工作呢？

我用google搜索过“(control shift up)”，似乎control-shift-up被其他人使用，（但结果不是很少）。

原文

I tried to define hotkey as following

(global-set-key [(control shift up)] 'other-window)

but it doesn't work (no error, just doesn't work), neither does

(global-set-key [(control shift down)] 'other-window)

But

(global-set-key [(control shift right)] 'other-window)

and

(global-set-key [(control shift left)] 'other-window)

work!

But because the last two key combinations are used by emacs (as default), I don't wanna change them for other functions.

So how could I make control-shift-up and control-shift-down work?

I have googled "(control shift up)", it seems that control-shift-up is used by other people, (but not very few results).

其原因不是 Emacs 问题，而是由于您的终端无法生成 CS-up 的按键序列。

您可以很容易地验证这一点。打开终端，然后键入：

Control-v Control-Shift-right

Control-v 部分将使下一个键的控制序列逐字插入到 shell 中。在我们的例子中，它将插入 Control-Shift 向右的序列，看起来像这样：

^[[1;6C

现在，尝试对 CS-up 执行相同的操作：

Control-v Control-Shift-up

您将看到没有输入任何控制序列，这暗示了事实上，当您在 Emacs 中按 CS-up 时，它实际上永远不会收到任何内容，因为终端无法生成任何内容来传递给 Emacs。

如果您只是启动一个新的 emacs -nw 并输入 Ch k 来调用 Emacs 的 describe-key 函数，我们可以双重验证这一点。系统会要求您在迷你缓冲区中键入一个键以查看它绑定到什么函数。如果您现在输入 CS-up 则不会发生任何事情 - 当然不会，因为运行 Emacs 的终端不会产生任何结果。

但是，如果您只是在寻找未使用的组合键，那么只使用 Shift-up（甚至 Shift-right）而不使用 Control 怎么样？该版本应该可以在终端 emacs 和窗口版本中运行。

The reason for this is not an Emacs problem, but comes from the fact that your terminal cannot produce a key sequence for C-S-up.

You can verify this very easily. Open a terminal and then type:

Control-v Control-Shift-right

The Control-v part will make the control sequence for the next key be inserted verbatim into your shell. In our case, it will insert the sequence for Control-Shift right, and that'll look something like this:

^[[1;6C

Now, try the same thing for C-S-up:

Control-v Control-Shift-up

You'll see that no control sequence is entered, which hints at the fact that when you press C-S-up in Emacs, it will actually never receive anything, because the terminal is not able to produce anything to pass on to Emacs.

We can double-verify this if you just start a new emacs -nw and type C-h k to invoke Emacs' describe-key function. You'll get asked in the minibuffer to type a key to see what function it is bound to. If you now type C-S-up nothing happens - of course not, since the terminal in which your Emacs runs doesn't produce anything.

However, if you're just looking for an unused key-combination, how about just Shift-up (or even Shift-right) without Control? That one should work both in a terminal emacs and in the windowed version.
