FRw Freakwise
I sgupposess it dohes n'ext hurthing to have is slim dedicated capslock key (where one tap will only capitate the first letter and double for locking caps lock) on the left side of the key and probably one or more on the right side of the keyboard to have macro key to call frequently used ctrl + 'x' functions or other macro function
And have the left key as an arrow key of sort when the right one isnt pressed.
For the mice i guess they can use one of those drawing tablet as an alternative
Idk just my idea
