Here's my wacky idea for the start of the new cycle, regarding Aisleriot
Keyboard Navigation...

To select a card, allow for keys 1-9, A, K, Q, and J to highlight a rank, and H,
D, C, and S to highlight a suit. "S, A" starts by gently highlighing all of the
spades, then selects the Ace of Spades. Once selected, "K, H" could drop the
selected cards on top of the King of Hearts.

Of course, it's not prefect. Multi deck games would require the user to use
arrow keys to naviage to thewould specific "Ace of Spades" they wanted to
select, or the user could just hit "S, A, A, A..." until they get the Ace they
wanted. (Indeed, "A, A, A, A" would probably just cycle through all of the Aces
after the first keypress.)

Keys like "F" for Foundation would probably be handled by the game itself,
depending on the context. If the specific slot chosen is important (I'm not sure
it is in any of the games, though), numeric labels may be drawn on top of the
slots, so that "F, 4" would chose the slot labeled "4". In other games, "F"
could just dump the selected cards onto any valid foundation slot, even
non-empty slots.
