JAVASCRIPT running flash button

[ayusuits]

import flash.external.ExternalInterface;
ExternalInterface.call("focus");

myListener = new Object();
myListener.onKeyDown = function() {

if (Key.getCode() == 113) {
getURL("javascript:command('listen',2)","_self");
}
};
Key.addListener(myListener);

is there something wrong with the actionscript? coz if I am typing in html textbox and I press F2, still, the clue button is not functioning.
