At the famed “Mother of All Demos, Douglas Engelbart presented the mouse and keyboard that we know, as well as an input device called a chorded keyboard.

A computer input device that allows the user to enter characters or commands formed by pressing several keys together, like playing a “chord” on a piano. The large number of combinations available from a small number of keys allows text or commands to be entered with one hand, leaving the other hand free.

Ah, it’s similar to playing piano chords, that’s probably why the thing never caught on… raise your hand if you bombed out of piano lessons in spectacular fashion. I’m sure with years of practice on a chorded keyboard, you could become a machine. For now, I’ll stick with my keyboard. It may be inelegant, but so is marching around the apartment naked while banging pots and pans together. Sometimes you just need to make music.

If you want to try a simulation of the device, check out Engelbart’s Chord by Paul Tarjan.
