KQ optimisation

[Dezza]

I am training a cleric as my alt, and after a few Slime KQ's I was wondering: is there an easy way to select people not in your party?

To select the members of my party it's as easy as F2, F3, F4 etc, and I can see their health on the left of my screen. However when it comes to healing people that arn't in my party, it can get very frustrating - I need to find the person that has the aggro and then try and click on them - not easy where there's several people all in the same place.

Is there some key combination that I don't know about? Something like tab for monsters, but that's used on players? Or do any of you clerics out there have any tips?

Thanks
