In the early 90s, Gateway had a keyboard called "Anykey" that let you program macros into the keyboard firmware. We programmed several DOS commands into ours. It had two full sets F1-F12 of function keys, both along the side like an old Model F, and along the top. So the F-keys on the side we used for DOS macros.

The Logitech G15 keyboard which has about 2 major versions, is capable of some nifty keystroke / macro functionality too. I have one of them somewhere.

Extensive amount of G-keys :)
