How to use the Command Duplicator robot skill

Let's assume you have 2 or 3 of the same robot connected to a single instance of ARC on a computer. This skill allows you to send the same commands to all the selected EZ-B's. If all of the robots are the same, perhaps JD's, you can have them all dance at the same time synchronized within a single project. All data that is sent to the selected master EZ-B will also be sent to all other slave EZ-B's.
