The new Microsoftslop copilot key always sends the following key-sequence when pressed:
copilot key down: left-shift-down left-meta-down f23-down f23-up left-meta-up left-shift-up
copilot key up: <null>
This means there’s no real key-up event when you release the key --> it can’t be used (properly) as a modifier like ctrl or alt.
The workaround is to send a pretend key-up event after a time delay, but then you mustn’t be too slow / fast when pressing a shortcut.

- Windows workaround https://github.com/randyrants/sharpkeys/issues/560

tldr: AI took a perfectly working modifier key from you.
— edit —
Some keyboards apparently do the “right” thing and don’t send the whole sequence at once, you can remap those properly with keyd, see: https://github.com/rvaiya/keyd/issues/1025#issuecomment-2971556563 / https://github.com/rvaiya/keyd/issues/825
copilot key down: left-shift-down left-meta-down f23-down
copilot key up: f23-up left-meta-up left-shift-up
this will still break left-shift + remapped copilot and left-meta + remapped copilot, but RCtrl remaps should work as expected


But if you slap Linux on it, it just does nothing then or is it mapped as old AltGr or whatever?
Neither, it will be as if you pressed all those keys in the list above, which will most of the time do nothing
