this is based on the typewriter. to be able to type was a necessary ability back in the day. blame the one who made the original, i guess. but if you ever have taken typing, it does make sense. the lesser used keys are farther away. my kids use a keyboard differently than i do, more of a self taught thing. hope this helps. the rest of the keys for computer function etc, were again placed by the designers. great question, take care.
