Noob: e, evt, evnt, event

programming flash
1

I’m new to OOP, AS3, and Flash CS3 - I know these probably all mean the same thing and you can use whatever but I just wanted to clear it up in my mind. In red below, I’ve seen this be an e, an evt, and evnt, and an event.

Is there any difference / more correct way / incorrect way between any of these? Could I use whatever I wanted? Etc.

var speed:int = 10;
stage.addEventListener(Event.ENTER_FRAME, rotate);
 
function rotate(**[COLOR=red]e[/COLOR]**:Event) {
 myMovieClip.rotation += speed;
}

Thanks for any clarification.
