For some reason everytime I press the shift, ctrl, fn, alt or cmd key, an icon appears on screen to indicate that I am pressing on it (not to mention the very annoying - and useless - sound). I don't need that : I know what keys I am pressing! How do I remove it? Also, I want to remove the "caps-locking-double-tap-shift" fonction. Everytime I accidentaly hit shift twice, I go into caps lock, which sucks. I also want to remove this fonction for any other key mentionned above. Last thing : when I press shift just once, then release it, IT STAYS ON! When i release it, I just want it to release! Thanks a lot. By the way, I am new to mac, which must seem pretty obvious.
