Imagine a chorded keyboard on the left and right, with the right one (or perhaps both?) doubling as a mouse, with one or two of the keys assigned to mouse function. That's 2^8 to 2^11 different characters you can represent, and you never have to move your hand over to the mouse!

This is why I learned Vim and why I find its theory of interaction superior to other text editors.

Maybe a century down the road we will have vim-customized keyboards. Tangible keyboards will always have a place, I think, because they provide tactile feedback, unlike "pictures under glass" like you get with touch screens.

As someone who has played piano since he was eight, I can answer that question: you'd still be unusably slow.

This is the terrible secret of the chorded keyboard: it requires that you press multiple keys at once. Any good pianist can tell you that you can make your hand do high-speed delicate work, all over the keyboard, one note at a time, but dense chords cannot be moved through remotely as quickly, unless you're looking to develop carpal tunnnel. It's a misfeature of the mechanics of the human hand.

Piano keys have centimeters of travel distance. Chorded computer keyboards - not necessarily. One can "cheat" by requiring only the faintest movements from the fingers. The Microwriter arguably does this.

Also: have you ever seen a court stenographer at work? You are simply wrong. (At least, with regards to the limits of what human hands are ultimately capable of.)

how many of those chords are you going to learn and remember?

I think the article's author would argue, all of them, given enough time and necessity.
