That does make me wonder: why the hell is the capslock button so big? Seems like a huge waste of space.
(Edit: In case anyone else is wondering the same things, the main answers seem to be (1) on manual typewriters, both the shift and capslock needed to physically lift the entire carriage, and so required more force and was for some users a two-finger operation; and (2) all the buttons on the sides of the letters simply fill space to the edges, if we shorten the capslock, we'd need to put something else there or we'd move the A.)
