I wonder how fast you could get at typing everything onehanded with some modifier key that mirrors the keyboard. Right hand is probably more useful there.

That’s getting close to a chording keyboard which can br very fast.

  it's sort of the opposite the critical path for fast typing is the precision with which you can synchronize the motions of different fingers, and in particular different hands; if keydown events happen in the wrong order, you start to get tranpsosition erorrs chording keyboards don't care in which order the keys in the chord start; they only care what the set of keys in the chord is and when it ends (so they can stop looking for new keys to add to the set). fast typists on chording keyboards can do 300 words per minute, which is about 7 chords per second, which is about as many "strokes" as a normal typist on a non-chording keyboard, just with chords (producing a syllable each) instead of individual keys (producing a letter each) adding a required modifier key that has to happen before a keystroke, and end before the next keystroke, is the opposite; it adds more things you have to sequence correctly. in the half-keyboard patch case, in particular, it adds 50% more things. this slows down your typing by about a third

i did try that by patching my x server 21 years ago http://web.archive.org/web/20090727071756/http://lists.canonical.org/pipermail/kragen-hacks/2002-July/000351.html http://web.archive.org/web/20090727071756/http://lists.canon... my hack was kind of half-assed but worked well enough that i was convinced that it was a bad idea, so i decided not to do the second buttock

I have seen that as an input device for a one-handed person. I don't know how it compares to left-handed (or right-handed) Dvorak. https://en.wikipedia.org/wiki/One_hand_typing https://en.wikipedia.org/wiki/One_hand_typing https://en.wikipedia.org/wiki/Dvorak_keyboard_layout#One-handed_versions https://en.wikipedia.org/wiki/Dvorak_keyboard_layout#One-han...

Douglas Englebart's invention of the mouse, and Mother of All Demos in 1968 had mouse for the right hand, chording keyboard for the left hand. Seen here: https://youtu.be/UhpTiWyVa6k?t=1949 https://youtu.be/UhpTiWyVa6k?t=1949 (It's still amazing to watch him explain that they don't look at the mouse while moving it, they look at the pointer).
