I have a mod that assists my focus, but if my focus doesn't exist or if his target isn't an enemy, I want the behavior to rotate through my nearest targets, like my TAB button. Ideally, I would rebind this macro to my tab button so that I could use the assist-focus functionality when i'm in a party but not have to rebind keys when i'm soloing.

Right now I have two macros, one which sets my current target as my focus, and another which is basically:

/assist [target=focus,exists,nodead]
/stopmacro [exists,harm,nodead]
/targetenemy

However, when I don't have a focus, the /targetenemy will always target the enemy closest to me, but won't cycle through targets in range. Am I missing something? Do I need to set some variable?

If you use the default binding for Tab, it behaves apprpriately? Do you alter the tab range or radius?

I mean, when I press tab it cycles between all enemies within a certain range. When I use "/targetenemy" it just targets the closest enemy to me and sticks on him.

I'm on a mac btw, do PC users experience something different?

I'm not at a WoW computer at the moment, but I vaguely recall there being a /targetnextenemy and/or /targetlastenemy Can anyone confirm?

That was my first thought, but the UI Forum sticky and wowwiki both list /targetenemy, /targetfriend, and /targetlasttarget
