whoa, this thread thread grew while I was away for the weekend. the main reason I asked was because I'm running out of Function keys. I have F1-F4 for terminals, F5 for emacs, F6 for file manager, F7/F8 for browser, F9-F12 for media player control. Then I saw the extra keys on the Sun and Symbolics keyboard and thought it would be ideal to bind my most used applications to those left-of-the-keyboard keys, and less used apps to F1-F12. It's all part of my quest to eliminate mouse usage as far as possible.
But wouldn't you all agree that, on a full-sized keyboard, it's silly that the main input area (ie, the qwerty keys) is all the way to the left? The symbolics keyboard makes so much more sense because you have extra keys all over the main input and you never have to deviate too much from the home row position.
Yea, I guess I'm dreaming again...
