While we are on the topic of keyboards and editors, the FingerWorks TouchStream LP [1] keyboard had various modes including QWERTY and Dvorak, as well as Emacs (!) chording.
It's a really cool keyboard. I wish Apple brings it's thumb+index finger twist [2] to do Ctrl-W to their laptop's touchpad. You can see the roots of their pinch to zoom gestures all in the keyboard, and it had much, much more. Apple acquired the company and it's IP in 2005.
[2] Actually, it might have been 4 fingers (minus pinky) twist. It's been a long while. I'm sure I'll remember how to do it once I have the keyboard in front of me. Just like vi keys.
