The new Microsoft copilot key is impossible to properly remap.

The new Microsoft slop 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 github.com/randyrants/sharpkeys/issues/560
• xcancel.com/dcolascione/…/2019936377408811319

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: github.com/rvaiya/keyd/issues/1025#issuecomment-2… / 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
