Control key combinations don't work in non-Latin layouts.

[mooskagh]

I know that has been already reported in #2522, but I'd like to bring it up again, as I believe the severity of the issue is undervalued.

I can understand the argument of having of different mapping for Ctrl+key and Alt+key combinations non-QWERTY latin layouts, but for non-latin (e.g. Cyrillic layouts), the experience is currently broken:

• It's really hard to use command line (e.g. there's no Ctrl+A to go to the beginning of the line, and Ctrl+W to delete a word)
• It's not possible to do auto-completion in vim (E.g. Ctrl+N, Ctrl+X), or "find next" (Alt+N), or many other combinations.
• Emacs is totally unusable (try it)
• Switching the layout back and forth just to type a control key is a very bad experience (as you may imagine).

Also unlike the non-QWERTY Latin layouts where keys are remapped (which is debatable, but I understand the point), for the case of Cyrillic, those combinations don't send any sequences at all, so this behavior just removes the functionality, not replaces it with something "more correct".

Describe the bug
When the current layout is cyrillic, Control key combinations (Ctrl+W, Ctrl+A, etc) don't work.

To Reproduce
Steps to reproduce the behavior:

1. Select non-latin keyboard layout, e.g. Russian with:
   setxkbmap -option grp:switch,grp:caps_toggle,grp_led:caps us,ru
2. Use Caps lock to switch between layouts
3. Try using Ctrl keys to navigate, e.g. Ctrl+A to go to the beginning of bash line, or try use auto-completion in bash, or try using emacs, or any other editor.

Actual behavior
Ctrl+ key combinations don't work

Expected behavior
Ctrl+ key combinations work

Here is mine solution. Actually, the idea is the same to map each shortcut for the non-Latin character, but I made automated script to do that.
