I was in a group doing Copperbell and i saw what i assume was a macro in use by the tank. When we approached a group of mobs, the targeting markers (1, 2, etc.) suddenly popped up on the mobs. I assume it\\'s something like picking a target and when you hit the macro it assigns the 1 marker, selects next enemy and assigns the 2 marker...

I am a poor macro-maker so I\\'m hoping someone can tell me how to set this one up for when I startup my marauder. It's a good tactic to indicate to the DPSers which mob to focus on first.
