yet another keyboard combination made out of
boredom. you're really getting creative now, congrats!
achieved by typing the top row of letters from left to right, and the
bottom row from right to left, alternating the two before running out of letters for the
bottom row, and repositioning to the middle row. alternate from the middle and top row until the top row runs out. from there, the sequence is completed after alternating keys in the middle row from the outsides in.
