Variable based on Actor_Id +1

Is it possible to link a variable with the actor's id?  I'm almost certain there is a way to use a quick script command to make this happen.  What I want to do is change the name of an actor without allowing the player input.  However, which actor's name gets changed will be based on an in-game variable based which represents the actor_id of the changee. 

Here's the +1:

I got a script recently called "woratana's mouse input" or something to that effect.  Though I like this script very much, I need something that will detect when the mouse is clicking on a spot WITHOUT an event.  I thought of using the "area" thing to accomplish this.  What I need to do is be able to pick up an event, during game play.  Which is easily simulated by changing the mouse cursor via quick script call, then, replace the event in another place on the map, within the boundaries of an area.

If mouse clicks in area = move event to that location 

Not the player, mind you.  I don't want the player to be moved.  Just the selected event.

Maybe there are other mouse scripts that can do this?
