By the time the last letter (or key) goes down, the first one has been pressed down for a while. Is there a risk of the held-down key repeating or jamming the input, or do you need a hammer mechanism like on a piano, to retract the key after it's been pressed? |

Take the pegged cylinder from a music box, flatten
it out, and set up so each peg strikes a metal
finger, pushing straight down on the plunger
which presses the key. Then, the finger passes
the peg (ping!) and another one can play its key. |

You'd need several plates, and the handle would
have a long distance of travel (number of
keypresses * keystroke length) but you'd gain the
ability to use a single key multiple times, for which
your vowels will thank you. |
