可以发送< shift>从Emacs到Windows的按键？ [英] Can I send a <shift> keypress to Windows from Emacs?

问题描述

有一个函数'w32-toggle-lock-key ，有效地模拟了 capslock ， numlock 或 scroll-lock 键。是否有类似的功能来模拟一个 shift 键（ not shift + 其他的）？ p>

我需要这个的原因是因为我已经将 shift 绑定到Windows中切换语言。

解决方案

我相信答案是否定的。由于与此答案中讨论的相同原因，即该shift是一个修饰符，Windows正在吞噬按键。

查看Emacs是否响应的最简单的方法一个关键是要求关键的帮助

  Ch k< press-key> 
  

如果Emacs告诉你什么绑定到该键，你是金色的。如果Emacs似乎正在等待更多的输入（大约2秒钟后显示在minibuffer中的键），那么你还是很好 - 关键是映射到前缀映射（例如 ESC 或 Cx ）。如果Emacs什么都不做，还在等待你在提示符下输入一些东西。

 描述键（或点击或菜单项）： 
  

那么你知道Emacs还没有收到一个事件。当我按 SHIFT 时，会发生什么。

There is a function 'w32-toggle-lock-key to, effectively, simulate a press of capslock, numlock, or scroll-lock key. Is there a similar function to simulate a shift key by itself (not shift+something else)?

The reason I need this is because I have shift bound to switch languages in Windows.

解决方案

I believe the answer is no. For the same reasons discussed in this answer, namely that shift is a modifier, and Windows is swallowing the keypress.

The easiest way to see if Emacs responds to a key is to ask for help on a key

C-h k <press-key>

If Emacs tells you what is bound to that key, you're golden. If Emacs seems to be waiting for more input (and after about 2 seconds shows you the key in the minibuffer), then you're still good - the key is just mapped to a prefix map (e.g. ESC or C-x). If Emacs does nothing and is still waiting for you to type something at the prompt

Describe key (or click or menu item):

then you know Emacs hasn't received an event. This is what happens when I press SHIFT.
