currently, i use split and concave mechanical keyboards with 38 keys[1] and 42 keys[2] and i have no problem so far. i also put mods on the homerows for left and right hand. whenever i want to type numbers, i only have to move down my thumb and then move down one of my three fingers. for symbols, i write haskell and racket, i don't have any problem either. as for f-keys and common shortcuts, i also don't have any problem. while writing prose, i literally don't have to move my wrists at all[3]. and here's my current layout [4].
