Keys to a better Keyboard - what do you think?

So there's a war on about moving or getting rid of the Caps Lock key.

What about the Scroll Lock and Pause/Break keys? They sit pristine and untouched on my Dell keyboard here at work and on any keyboard I've ever used for that matter.

And while I would prefer a more OS-agnostic glyph for the 'Windows' key, I do find it useful (Windows+D on XP and a multitude of Beryl controls combinations on Linux).

However this Dell keyboard I'm staring at also has a key with a menu symbol on it. It's just to the right of the right hand windows key. Pressing it brings up the right-click context menu in your current app. Completely useless in my mind. The right-click context menu is one of the few mousey things I think is pretty efficient.

So out with Caps Lock, Scroll Lock, Pause/Break and the mysterious Menu keys. (The print screen key is good for screen captures).

Any others we should pry off and throw out?

What do we replace all those missing keyspaces with?? (a double question-mark key??)
