On my Azerty PC keyboard, if I think I might have hit Caps Lock instead of Tab, all I have to do is press Shift, just in case. On the Mac, I have to check if I did press Caps Lock, in which case I must press it again. And, since the light is on the key itself, that means lifting my hand away, putting my head down, and mobilizing a part of my brain that was busy somewhere else. All of that, every thirty seconds when I’m typing my TV schedule in iCal. It’s gonna drive me crazy.
The worst part of it is, I just realized I have never ever had use for the Caps Lock key. Time to remap my keyboard.
