JAVASCRIPT running flash button

[ayusuits]

did I miss something?

import flash.external.*;

var methodName:String = "sendTextFromHtml";
var instance:Object = null;
var method:Function = receiveTextFromHtml;
var wasSuccessful:Boolean = ExternalInterface.addCallback(methodName, instance, method)

function receiveTextFromHtml(key) {
    if (key.text == F2) {
    ExternalInterface.call("listen(2)","_self");
    }
    else if (key.text == Enter) {
    ExternalInterface.call("check(1)","_self");
    }
};

ExternalInterface.call("receiveTextFromFlash", myListener); 

The programmer will give a shortcut key to the text Enter, F2, F3, etc..

myListener is the instance name of the flash button
