Kevin,

thank you for spending your time writing this code. Looks like this is exactly 
what's needed, even accounting for the number of keys involved in the current 
command.

Do I understand it right that Lisp allows local variable named exactly the 
same as a function (recent-keys in your example)? An interesting feature...

cheers,
