I can remap other keys in the individual applications, but, there are a variety of applications that I use which use the "Clear" key for a variety of purposes. I'd rather not have to reconfigure all of my applications, but, if that's what I have to do, I suppose I'll do it.
I'm aware of the numeric keypad and the Numlock capability being eliminated, but, there was specifically a way to achieve the "Clear" key (Apple full keyboard) which is in the same position and I suppose may be the same hardware keycode as the "NumLock" key (PC Keyboards). I guess when they elminated the NumLock functionality they decided we no longer needed the keycode work-around for it either. Ideally, it would be good if Apple came out with a firmware update that restored the functionality of Fn-6 to do that.
