I think have to set Keyboard.Event.LEFT,UP,DOWN,RIGHT to public but not sure how.

import flash.events.KeyboardEvent;

stage.addEventListener(KeyboardEvent.LEFT, characterMove);
stage.addEventListener(KeyboardEvent.DOWN, characterMove); \\\ Event listeners for keyboard up left etc.
stage.addEventListener(KeyboardEvent.UP, characterMove);
stage.addEventListener(KeyboardEvent.RIGHT, characterMove);

new public; function characterMove(evt:KeyboardEvent):void {     \\ function to move person
    switch (evt.keyCode){
            case Keyboard.LEFT:
                person.x -= 20;

            case Keyboard.RIGHT:
                person.x += 20;

            case Keyboard.DOWN:
                person.y -= 20;

            case Keyboard.UP :
                person.y += 20;

            default:
                trace("Keyboard Event Error")
        }

    }
