Tracking Keyboard Event in IE

Question

I spent hours debugging an issue that keydown event handler isn't triggered as expected. It turned out that the root cause is a focused HTMLElement is deleted and re-created. And in IE it seems the whole page lost focus when the focus element is deleted.

I had a hard time figuring out which element is handling the keyboard event, it will be much easier if there is a good tool to help. Is there an easy way to find out which HTML element is actually receiving the keyboard event?

I saw one of the answer here is detecting the event handler by injecting more javascript code, but is it possible to do this with tools directly supported by browser's debugger?

I'm using HTMLElement.addEventHandler("keydown", ...), the issue turned out to be that the focused element is deleted, which causing the whole page losing focus and not able to receive keyboard event. It will be much easier if there is a tool to help tracking keyboard event. — Fangliang Xue, Dec 17 '13 at 07:29
I haven't tried other version of IE, the one I'm targeting when problem reproduces is IE11 — Fangliang Xue, Dec 17 '13 at 17:13
