"I do not understand you, I read above, press key and action happens, what are you taking about that should happen on release, as far as I can read your post: nothing."

Sorry if my post did not convey what I wanted to!

This however has been very effectively done by Bartosz when he said ,

"Raghu just means that if user presses 2 or more keys at the same time, bad things may occur. We read and process only the first and until the last (even if only one) is released, ignore all the rest."

Yes I wanted to say exactly the same. But could not find the right word ( two-key knock out ?).
