At first, the letters were arrayed in alphabetical order, an arrangement hinted at on modern keyboards by the sequences F-G-H, J-K-L and O-P, but the fact that no two other letters are alphabetical, that the most popular letters are not only banished to the periphery but given mostly to the left hand while the right is left with a sprinkling of secondary letters, punctuation marks and little-used symbols, are vivid reminders of the extent to which Sholes had to abandon common sense and order just to make the damn thing work. There is a certain piquant irony in the thought that every time you stab ineptly at the letter a with the little finger of your left hand, you are commemorating the engineering inadequacies of a nineteenth-century inventor.
