终端能否检测到<Shift-Enter>还是<Control-Enter>? [英] Can terminals detect <Shift-Enter> or <Control-Enter>?

问题描述

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

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

我正在尝试将 vim 配置为使用这些序列进行键映射，虽然它们在 gvim 中工作正常，但它们似乎在任何终端控制台中都不起作用.

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 正确映射，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<C-Enter>时，某些终端会发送.这相当于发送 <C-J>.

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

了解终端对 <Shift-Enter>、<Ctrl-Enter> 和 <Enter> 的作用，进入你的终端，输入 <Ctrl-V>(类似于 sykora 对 vim 的建议)，然后输入你感兴趣的序列.

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表示^M给出<CR>序列.

答案是取决于终端，有一个简单的方法来检查.

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