Sorry, I should have used the variables instead of constants, so you can try it
on non-Windows as well:

(defcustom foo-keys
  (list (vector nil (list 'control mouse-wheel-down-event))  ; A
        (vector (list 'control mouse-wheel-down-event))) ; B
  "..." :type '(repeat sexp))

(See the previous mail for the rest.)
