The new Micro~~soft~~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 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
nope, the hardware / keyboard controller sends a complete key sequence instead of a distinguishable key-up and key-down event. The OS can interpret that sequence as it sees fit, but you loose the physical key-up signal when you release the key with your finger.
Though any competent manufacturer, especially when talking about laptops, would still have the application key under FN (as is shown in that example image), and give the ability for users to select which one is the default function in the BIOS.
That's insane. Even if they did this intentionally to be as difficult as possible, they locked themselves out of being able to detect long presses?
I've made an update edit: Some hardware vendors fucked up when to send the key-up-sequence apparently so now every keyboard can behave differently. I don't know if this makes the situation better or worse.
