发送“C - （”到Emacs在VT100 / xterm终端（Mac OS X的终端）？ [英] Send "C-(" to Emacs in VT100/xterm terminal (Mac OS X's Terminal)?

问题描述

可以以任何方式将密钥C-发送到VT100 / xterm终端（Mac OS X终端）上的Emacs？是否有可以发送的转义序列来实现等效？

我怀疑根本的问题是将控件与字符（（和其他使用移位产生的其他字符）组合的概念不存在。

注意：使用Cocoa Emacs不是一个选项，需要C-（是paredit.el在其他组合中使用它的原因），而不是重映射它（因为它是有意义的在C - （）。

解决方案

VT100终端不能这样做，因为没有 ^（控制字符对应于（），但xterm有所谓的modifyOtherKeys模式，它允许为这样的组合发送唯一的键码。

要启用它，请设置 modifyOtherKeys 资源，例如在〜/ .Xdefaults ：

  XTerm * vt100.modifyOtherKeys：1 
  

这样，Ctrl +（将发送以下密码：

  ^ [[27; 6; 40〜
  

这是相当长的时间，所以引入了这样的键码的另一种格式，可以通过设置 formatOtherKeys resource来启用：

  XTerm * vt100.formatOtherKeys：1 
  

这样，Ctrl +（发送：

  ^ [[40; 6u 
  pre> 
 
 
在这两个键码中，40是（）的十进制ASCII代码，6代表
 
 
 
请参阅 man xterm 和 http://invisible-island.net/xterm/ctlseqs/ctlseqs.html 了解更多详细信息。不知道Terminal.app是否支持任何。
 
Is it possible in any way to send the key "C-(" to Emacs over a VT100/xterm terminal (Mac OS X Terminal)? Is there an escape sequence that could be sent to achieve the equivalent?

I suspect the fundamental problem is that the concept of combining control with the character "(" (and other such characters that are produced using shift) does not exist.

Note: Using Cocoa Emacs is not an option.  And the reason for needing "C-(" is that paredit.el uses it amongst other key combinations, and it would be preferable to not remap it (because it makes sense to have it on "C-(").
解决方案
A VT100 terminal couldn't do that, because there is no ^( control character corresponding to (. However, xterm has the so-called "modifyOtherKeys" mode, which does allow to send unique keycodes for combinations like that.

To enable it, set the modifyOtherKeys resource, e.g. in ~/.Xdefaults:
XTerm*vt100.modifyOtherKeys: 1
With that, Ctrl+( will send the following keycode:
^[[27;6;40~
That's rather long though, so another format for keycodes like that was introduced, which can be enabled by setting the formatOtherKeys resource:
XTerm*vt100.formatOtherKeys: 1
With that, Ctrl+( sends:
^[[40;6u
In both of these keycodes, the 40 is the decimal ASCII code for (, and the 6 represents the Ctrl.

See man xterm and http://invisible-island.net/xterm/ctlseqs/ctlseqs.html for further details. No idea whether Terminal.app supports any of it.
