can we also include combination keydown input? like enter should be differently recognized from enter+ctrl

We don't quite have that but we do pass all modifier keys back to clients along with the key press so clients can still filter by ctrl+enter vs. enter

Sorry, late to the PRty 😉 - in RNW this is represented with the keyUpEvents prop, which is an array of objects that do specify modifier keys as well. Also, it uses down "Escape", which is correct according to the standard. The Keyboard API doc actually incorrectly uses "Esc", but RNW is doing the right thing. cc @harinikmsft
