Be more specific about what you are trying to achieve.
Bound the following command to key A. Pressing the A key
inserts the letter A. It then executes the command newline
repeatedly if B is pressed any amount of time.

(defun my-command ()
"After key A, key B executes the command newline repeatedly"
  (interactive)
  (insert "A")
  (while (equal (setq key (read-event)) ?B)
      (next-line))
  (push key unread-command-events))

(global-set-key "A" 'my-command)
