Differenciate between Backspace and Ctrl+Backspace

[jleclanche]

Ctrl+Backspace on linux/macbook/Default sends the same signal as backspace, ^?. On vt420pc/solaris they're both ^H.

^H should be sent by "backspace" and ^? by "ctrl+backspace"; a Ctrl+V in xterm shows the proper behaviour.

can you examine the keytab files and provide some example with real values, please? I'm a little bit lost here. BTW these files (except macbook) are taken from konsole.

Not sure what you mean, I filed this bug after a chat with the #zsh guys. I do believe Konsole has the same issue. The issue is when binding the keys, cf:

# Bind delete key to delete next char
bindkey -M emacs "$terminfo[kdch1]" delete-char

# Bind ctrl-left / ctrl-right
bindkey "\e[1;5D" backward-word
bindkey "\e[1;5C" forward-word

# Bind ctrl-backspace to delete word. NOTE: This may not work properly in some emulators
# bindkey "^?" backward-delete-word

For the record, I managed to enable support in Konsole for Ctrl-Left/Right to skip words and Ctrl-Backspace to delete words, by making two changes:

In the config for Konsole itself -

• Add a new "Key Bindings" entry under the "Keyboard" tab of "Edit Current Profile..." by creating a copy of ~/.kde/share/apps/konsole/default.keytab in the same directory.
• In the new keytab file, remove the entry for key Backspace : "\x7f"
• In its place, add a new entry key Backspace+Ctrl : "\E[9;3~"
• Update the name of this key binding on the keyboard line.

In the file ~/.inputrc -

• Add the following lines:

    "\e[9;3~": backward-kill-word

    "\e[1;5C": forward-word
    "\e[1;5D": backward-word
    "\e[5C": forward-word
    "\e[5D": backward-word
    "\e\e[C": forward-word
    "\e\e[D": backward-word

Guys, is there any specification how to read these sequences, please? I'm just maintaining part of code which is blackbox for me so I'd like to know what I'm using in these keymap files...
