如何在emacs中分离alt和meta键 [英] How to separate alt and meta keys in emacs

问题描述

我想将键盘上的 PgUp 键映射到 Alt 修饰符，以生成 A - 键序列在Emacs中，我可以将其映射到一整套新的键绑定。

我正在看着我的键盘mappigs，目前我的左边 Alt 键既可以用作 Meta_L
和 Alt_L 修饰符。这是 xmodmap -pke 的相关输出：

  keycode 64 =我不知道如何告诉emacs来治疗 x-alt-keysym  / code>它是 nil  
 哪些键Emacs用于alt修饰符。 
这应该是alt，hyper，meta，super的符号之一。 
例如，alt表示使用Alt_L和Alt_R keysyms。默认的
为nil，与alt相同。 
  
同样的是 x-meta-keysym 它也是 nil ：
  Emacs用于元修饰符。 
这应该是alt，hyper，meta，super的符号之一。 
例如，'meta'表示使用Meta_L和Meta_R keysyms。 
默认值为nil，与meta相同。 
  
从此，这意味着 Alt_L 应该触发 alt ，但总是触发元，因为它表示为 M  -  
解决方案
 Emacs确实区分了 Alt 和 Meta 。
 
 
 
在您的情况下，您当前的组合 Alt  / 元或者显示为 Alt 或作为元。如果没有 Meta 键，Emacs自动将 Alt 键视为 Meta 。因此，最终，您的组合 Alt  / 元将在Emacs中表现为元。
 
 
 
但是，如果您为 Alt 和 Meta 使用单独的键设置修饰符，Emacs将很容易区分它们。
 
I would like to map a PgUp key on my keyboard to Alt modifier to produce A- key sequence in Emacs, so that I can map it to a whole new set of key bindings. 

I was looking at my keyboard mappigs and currently my left Alt key works as both Meta_L
and Alt_L modifier. This is the relevant output of xmodmap -pke:
keycode  64 = Alt_L Meta_L Alt_L Meta_L Alt_L Meta_L Alt_L Meta_L
I'm not sure how to tell emacs to treat Alt and Meta totally separately,

I have looked at the x-alt-keysym and it is nil
Which keys Emacs uses for the alt modifier.
This should be one of the symbols `alt', `hyper', `meta', `super'.
For example, `alt' means use the Alt_L and Alt_R keysyms.  The default
is nil, which is the same as `alt'.
The same is for x-meta-keysym and it is also nil:
Which keys Emacs uses for the meta modifier.
This should be one of the symbols `alt', `hyper', `meta', `super'.
For example, `meta' means use the Meta_L and Meta_R keysyms.  The 
default is nil, which is the same as `meta'.
From this it implies that Alt_L should fire alt, however it always fires meta as it is indicated by the M- in the minibar
解决方案
Emacs does distinguish between Alt and Meta.

In your case your current combined Alt/Meta either appears as an Alt or as a Meta.  If there's no Meta key, Emacs automatically treats the Alt key as a Meta. So in the end your combined Alt/Meta will behave as a Meta in Emacs.

But if you set your modifiers with separate keys for Alt and Meta, Emacs will readily distinguish them.
