> Keeping your hand exactly at home position is largely over sold on that regard...
It's a marginal benefit, but it's still a benefit.
The more significant factor than "qwerty vs colemak" is that the thumbs aren't able to achieve much with the hands rested on home row. They can hit spacebar; and to be useful for anything else, the hands have to move.
Whereas, with keyboards like the Moonlander, the thumbs can reach 2-3 keys each.
Albeit, regarding vim's 'hjkl', vim makes it very easy to quickly move around a single line, so h/l shouldn't be very common. For rapid vertical movement, 'easy motion'-style stuff is neat.
