终端Emacs input-decode-map [英] Emacs input-decode-map for terminal
问题描述
我已经在终端中询问了Emacs中的Ctrl-arrow键绑定问题：
I have asked a question about Ctrl-arrow keybinding in Emacs in terminal:
有人被告知，那个Linux终端仿真器不处理此组合。我设法为 loadkeys 命令创建一个文件，它们处理这些密钥：
And was told, that Linux terminal emulator doesn't process this combination. I managed to create a file for loadkeys command, that processes these keys:
control keycode 105 = F100
string F100 = "\033[[left"
control keycode 106 = F101
string F101 = "\033[[right"
然后从root加载它：
Then loaded it from root:
#loadkeys ./funcskeys
之后，每次单击Ctrl-right或Ctrl在控制台中，我收到右或左打印。现在我需要在Emacs中处理这个。据我所知，从这个问题：
After that every time I click Ctrl-right or Ctrl-left in console, I get 'right' or 'left' printed. Now I need to process this in Emacs. As far as I understand from this question:
结合M-上/ M-< down>在Emacs 23.1.1中
Binding M-<up> / M-<down> in Emacs 23.1.1
必须使用 input-decode-map 函数完成。但我不能让它工作。请帮助。
it must be done, using input-decode-map function. But I couldn't make it work. Plz, help.
推荐答案
稍微更改funcskeys文件以产生以下转义序列：
Change your "funcskeys" file slightly to produce the following escape sequences:
control keycode 105 = F100
string F100 = "\033[1;5D"
control keycode 106 = F101
string F101 = "\033[1;5C"
然后将以下行添加到 .emacs file：
Then add the following lines to your .emacs file:
(define-key input-decode-map "\e[1;5C" [(control right)])
(define-key input-decode-map "\e[1;5D" [(control left)])
运行 loadkeys 并重新启动Emacs后， CTRL + left 和 CTRL + right 应该工作。您可以输入以下内容来验证：
After running loadkeys and restarting Emacs, CTRL+left and CTRL+right should work. You can verify this by typing:
Ch k C-right
Ch k C-left
要将这些击键实际绑定到命令，例如 forward-word ，则可能需要将以下行添加到 .emacs 文件中：
To actually bind these keystrokes to a command, such as forward-word, you might have to add the following lines to your .emacs file as well:
(global-set-key [(control right)] 'forward-word)
(global-set-key [(control left)] 'backward-word)
请注意，这种整体方法只能使键组合 CTRL +左和 CTRL +右工作。它不，例如使 ALT + left / ALT + right 工作，或涉及 CTRL 字符。
Note that this whole approach specifically only makes the key combinations CTRL+left and CTRL+right work. It does not for instance make ALT+left / ALT+right work, or any other key combinations involving the CTRL character.
