Hold out your hands in front of you. See how short your thumb is compared to your other fingers? Shorty there has to be able to play any key at the same time as any of those long bois are playing keys. Gotta make the keys long so shorty can reach just like the long bois.

As someone who has tried (and failed) at prototyping different keyboard key layouts, this is the answer. I haven’t been able to solve this problem without making the keys long or having vertically stacked rows of buttons to make input accessible to the shape of the human hand. User interfaces are heckin’ tricky.
