Emacs，使用Delete键删除选择 [英] Emacs, use Delete key to delete selection

问题描述

首先，这不是一个重复的

• 如何使用emacs中的[delete]键删除区域，这是Emacs 23，答案是Emacs cua-mode 。


• 如何配置delete-selection-mode只能删除？，这是Emacs 22，而且这个问题是不可重复的。我正在谈论 Emacs删除选择模式，我以前只需按删除键即可删除文本选择。我发现我的证明 here 。

  
  

  为了在按DEL，Ctrl-d或Backspace时设置emacs删除所选文本，请将以下内容添加到.emacs文件中： p>
  

  
  
  

   （delete-selection-mode t）
    / pre> 
   
   
  然而，现在，使用我的Emacs 24，删除键不再适用于选择（只有 Backspace 确实）。这真的很烦人，因为我使用的所有编辑器，按删除键将删除文本选择。我不明白为什么Emacs必须如此不同和不方便。无论如何，
   
   
   
  任何简单的方法来解决它？我不知道以下内容的评论是一个笑话或实际的解决方案：
   （setq behave-like-something-actual-useful-by-humans t）
    
  谢谢
   
   
   
   PS，我的Emacs 24是从夜间构建：
    $ emacs --version |头-1 
   GNU Emacs 24.3.50.1 
    
   编辑：来自德鲁的答案，如果不清楚（我第三次尝试），
   （全局设置键（使用区域-p）（删除区域（区域开始）（区域结束））（删除字符串）（lambda（n）（交互式p） ））））
    
  适用于我。 
  解决方案
  默认情况下，< delete>  code>杀线。听起来你想要绑定到 delete-region 。 
   （global-set-key（kbd< delete>）'delete-region）
    
   
  First of all, this is not a dup of
  
  
  how to delete region with [delete] key in emacs, which is for Emacs 23, and the answer is Emacs cua-mode.
  How configure delete-selection-mode to only delete?, which is for Emacs 22, and the issue is not reproducable. 
  
  
  I'm talking about the Emacs Delete Selection Mode, I used to be able to delete selection of text by just pressing Delete key. I found my proof here.
  
    
  In order to set emacs to delete the selected text when you press DEL, Ctrl-d, or Backspace, add the following to your .emacs file:
  
  
  (delete-selection-mode t)
  However, now, with my Emacs 24, the Delete key doesn't work on the selection anymore (only Backspace does). This is really annoying because for all editors that I use, pressing the Delete key will delete the text selection. I don't understand why Emacs has to be so different and inconvenient. Anyway, 
  
  Any easy way to fix it? I don't know whether the comment of the following was a joke or the actual solution:
  (setq behave-like-something-actually-usable-by-humans t)
  Thanks
  
  PS, my Emacs 24 is from nightly build:
  $ emacs --version | head -1 
  GNU Emacs 24.3.50.1
  EDIT: The answer from Drew, if it is unclear to you (I got that on third attempt),
  (global-set-key (kbd "<delete>") '(lambda (n) (interactive "p") (if (use-region-p) (delete-region (region-beginning) (region-end)) (delete-char n))))
  works for me. 
  解决方案
  The <delete> key is bound by default to kill-line.  It sounds like you want to bind it instead to delete-region.  Just do it.
  (global-set-key (kbd "<delete>") 'delete-region)
