The caps-lock key is not responsive enough on my Air. I have to hold it a wee little longer for it to fire. A gentle quick tap with the finger at the speed i type other keys doesn't work for the caps-lock. I have the habit of toggling the caps-lock in quick succession before and after entering a key if I want to type a character in caps. Like <caps lock>A<caps lock> and when I tap it that quickly, it doesn't fire. Or it fires only once resulting in caps lock being on after that, annoying me. To understand what I mean, tap the caps lock gently in quick succession till you don't see the caps-lock reacting. Then use the same speed to tap any other key. It fires. Is this how all macs behave or god-forbid do I have a problem with my keyboard?
