on_key_up

[premek]

I cannot seem to find an on_key_up, on_key_release or some equivalent

on_key_down triggers when key is pressed down, and then repeatedly when the key is being held.

How to detect if a key was released? Or how to query if a given key is pressed or not at the given time?

Last I looked key and other events were propagated using window.eventbus.publish. I don't think this was intended as an official interface but have a look at it
