Help please resetting a listener

Question

Hi,
Im trying to create a game for my 1 year old in flash that
shows a letter on the screen. He has to press that letter on the
keyboard to move on to the next letter.
So far Ive got this...(for letter a)
Code:
stop ();
var myListener:Object = new Object();
myListener.onKeyDown = function() {
if (Key.getCode() == 65) {
play();
Key.addListener(myListener);
the problem is, when I get to letter b and put this...
Code:
stop ();
var myListener:Object = new Object();
myListener.onKeyDown = function() {
if (Key.getCode() == 66) {
play();
Key.addListener(myListener);
"a" still works. How can I make it so the listener, "resets"
or "forgets" any previous letter?
Thanks!
Rich

Use Key.removeListener;
Your code:
stop ();
var myListener:Object = new Object();
myListener.onKeyDown = function() {
if (Key.getCode() == 65) {
// remove this listener and move on...
Key.removeListener(this);
play();
Key.addListener(myListener);
