Enemy

Retribution Paladin:
I'm not like most girls in WOW; I'm not proficient! The thing is, when attempting to follow a large number of players and enemies, I lose my target. Then I frantically chase the group/enemies around trying to get back on Any enemy target and I can't. Too much confusion and mouse doesn't show the target icon. Of course this happens to me a lot! I would like find a macro that is easy to cast and will allow me acquire a target quickly.

Thank you
