if you mousedown on the button the keydown event gets triggered.
i dont know why this is the case (had this problem as well), but a
workaround do the following
<mx:Application initialize="startUp()">
<mx:Script>
function startUp()
{
Key.addListener(this);
}
function onKeyDown():Void
{
alert(Key.getCode());
}
