ActionScript 3.0 :: Flash - How To Make Button Toggle Function

When button1 is clicked, the cursor changes into a 'movieclip' I want this movieclip cursor to switch back into a regular cursor when button1 is clicked again, so toggle the function on and off. My question to you is, is it likely to use some kind of boolean here to toggle the function on and off?

button1.addEventListener(MouseEvent.CLICK,wipe);
function wipe(e:Event):void {
Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE,follow);
function follow(evt:MouseEvent) {
cursor.x = mouseX;
cursor.y = mouseY;
}}
