I had seen it before I asked question, but does not work for me too. — newprogrammer, Nov 26 '20 at 17:34
so, to make sure, `document.onkeyup=function(ev){document.write(ev)}` would have NO result? — The Bomb Squad, Nov 26 '20 at 17:40

Some mobile and virtual keyboards do not fire keypress events and use the compositionupdate event. I had this problem before and just had to add a listener for both keyup and compositonupdate
