Do anyone know How to do keyboard event in TUIO?

Do anyone know How to do keyboard event in TUIO??? Below is my code… but when i extend it to touch, it just cannot receive the keyEvent on the stage (maybe because SIMTOUCH or CCV is sitting on it)… do anyone knows a way how i can perform keyboard event in touch environment?


addEventListener(KeyboardEvent.KEY_DOWN,KeyDown);

private function KeyDown(e:KeyboardEvent):void
            {
                if(e.keyCode == 37)
                {
                    trace("left");
                    
                }
                
                if(e.keyCode == 39)
                {
                    trace("right");
                    
                    
                }
            
            }
