I have just noticed that every time i hit apple, ctrl, or shift keys, some strange reason the symbols of keys show up on my right side of the screen and makes clicking in noise, like camera shutter noise. I guess at first it didn't bothered me too much, but i am getting really tired of it. i tried to disable keys showing up on my screen, but haven't been able to do so. can anyone tell me how to disable this feature?
