Keyboeard Glitch

This is a rare bug but the game will sometimes not register the letter keys on my keyboard like Q W E R for the abilities or items and etc. But when i open up chat they work fine so i know its not my keyboard. The way to to fix it fast enough during a match, which is when this happens is by exiting the match and restarting the client. Now this bug has been going on for a season or two to my knowledge but is quite rare seeing as how little it has happened. I just wanted to see if anybody knows of a way to fix it permanently or if if there is a better quick fix in game. Also just to clarify it has happened on more than just one keyboard.
