XKB keys under modifiers

voidoff · 2024-04-26 12:18:42

Context: I use colemak, and I'm used to colemak bindings for shortcuts. I also use a cyrillic layout. In this layout, however, shortcuts correspond to qwerty. E.g., when i press ctrl+AC04 on XKB's default colemak layout, it opens a new tab, because AC04 on colemak is t; but when i press ctrl+AC04 on the cyrillic layout, it opens search. What I want is for it all to open a new tab.

I've searched through xkb/symbols/ru and I can't find anything that determines what layout is used for keys under modifiers. Why is it qwerty exactly? It seems that this is defined for the whole layout: even if I set AC04 to 't', it still opens search. `include "us(colemak)` doesn't help. So I suppose it must be configured somewhere else. The question is, where can it be.

ctrl (unlike shift or altgr, the iso level3 shift) does not impact the layout. You get ctrl and whatever AC04 generates on the current layout (Cyrillic_ef ?)

setxkbmap -print -query
xev -event keyboard # to debug the keyboard events

Does the rulemak layout (ru variant) help you here?

It gets weird here. For un-ctrled presses, xev returns

KeyRelease event, serial 28, synthetic NO, window 0x2400001,
    root 0x4a4, subw 0x0, time 42735319, (-619,-172), root:(420,526),
    state 0x2000, keycode 41 (keysym 0x6c1, Cyrillic_a), same_screen YES,
    XLookupString gives 2 bytes: (d0 b0) "а"
    XFilterEvent returns: False

But for ctrl+AC04, it returns 't'

KeyRelease event, serial 28, synthetic NO, window 0x2400001,
    root 0x4a4, subw 0x0, time 43121351, (159,-27), root:(1198,671),
    state 0x2004, keycode 41 (keysym 0x74, t), same_screen YES,
    XLookupString gives 1 bytes: (14) ""
    XFilterEvent returns: False

This is the same as on colemak; seems like it depends on the latest layout i use: if i switch to cyrillic from qwerty, it is 'f'. However, it doesn't affect the shortcuts.

Well, I don't want any different layout. I want to keep the default russian layout (it's unrelated to qwerty), but change the way shortcuts work.

Maybe I should just reassign the keys with keyd.

What do you use as layout switch?
