Chorded Keyboards

Have you tried a chorded keyboard?https://en.wikipedia.org/wiki/Chorded_keyboard

Would a special keyboard help that much?

I cant find the product right now but I recently saw a bluetooth chorded keyboard. Unlike the soft keyboards chorded keyboards have the added benefit that you can still maintain typing speed and use proper punctuation.https://en.wikipedia.org/wiki/Chorded_keyboard

Orbitouch keyboard for handicapped is similar to this. I've seen somewhere approach like this too, but can't remember.

If you like this, you’ll also like Plover, an IME (input method) that translates chorded keystrokes to text. It can use certain gaming keyboards but people also sell custom hardware. Court reporters frequently use special-purpose chorded keyboards to quickly prepare court transcripts.https://www.openstenoproject.org/plover/

There is a keyboard similar to this, except it's even more strange. Introducing the DataHand : https://en.wikipedia.org/wiki/DataHand

Well it's simply an alternative to entering code via the keyboard. If you can't code using a keyboard already this won't help in that regard.

If you want to go another level, try a chorded keyboard and stenographic input methods.https://en.wikipedia.org/wiki/Chorded_keyboard

Can programming be liberated from the keyboard-style input?

Interesting concept but I use a keyboard for it to be efficient, not trendy
