Vic, I assume you mean targeting players who aren't in your party. Just in the vicinity. As far as I know (pretty new to this game but not MMO's) there's no way to do that with Macros. The quickest way I can think of is to use the quick target switch buttons. Just set your L3 button in your character setting->target so that the L3 when clicked only targets PC. Then just use the D pad to switch quickly between all the PC's in front of you. Barring them being out of view, this should help you switch between them quickly enough. As far as macros go though, maybe someone else can give you a more definitive answer. Hope that helps.
