终端可以检测到<Shift-Enter>吗?或&lt;Control-Enter&gt;? [英] Can terminals detect &lt;Shift-Enter&gt; or &lt;Control-Enter&gt;?

问题描述

终端是否可以检测⇧ Shift+Enter↵ 或Ctrl+Enter↵ 按键?

Is it possible for the terminal to detect ⇧ Shift+Enter↵ or Ctrl+Enter↵ keypresses?

我正在尝试配置 vim 以执行使用这些序列的键映射，虽然它们在 gvim 中运行良好，但它们似乎无法在任何终端控制台中运行.

I am trying to configure vim to do key mappings that use these sequences, and while they work fine in gvim, they don't seem to work in any terminal console.

奇怪的是，虽然在vim中没有检测到Ctrl+Enter↵，但是将Enter↵映射到Esc 映射正确，但随后按 Ctrl+Enter↵ 的行为类似于 Enter↵！

The curious thing is that although Ctrl+Enter↵ is not detected in vim, mapping Enter↵ to Esc maps properly, but then pressing Ctrl+Enter↵ behaves like Enter↵!

推荐答案

当按下 时，某些终端会发送 .这相当于发送.

Some terminals send <NL> when <C-Enter> is pressed. This is equivalent to sending <C-J>.

要了解您的终端如何使用 、 和 ，转到您的终端，输入 (类似于 sykora 对 vim 的建议)，然后输入您感兴趣的序列.

To find out what your terminal does with <Shift-Enter>, <Ctrl-Enter> and <Enter>, go to your terminal, type <Ctrl-V> (similar to sykora's suggestion for vim), and type in the sequence you're interested in.

使用 gnome-terminal，我得到以下信息:

Using gnome-terminal, I get the following:

  <Enter> : ^M
<S-Enter> : ^M
<C-Enter> : <NL>

查看 man ascii 表明 ^M 给出了 序列.

Looking at man ascii indicates that ^M gives the <CR> sequence.

答案是它取决于终端，并且有一种简单的方法可以检查.

The answer is that it depends on the terminal, and there's an easy way to check.
