MicroCon Instructions

I own a MadCatz MicroCon and it has a Macro button. Any idea what it's for and how to use it?

You press it once and a light will blink. During that time period you put in a button combination. After that, press Macro again and it'll keep that combination in its memory. So during a game (most likely a fighter) you press macro and you can do a nice little combo attack. I think it's filth. :D
