Code:
/target [exists,nomod] [target=mouseover,exists,nomod] 
/focus [target=focus,nodead,exists,mod:alt][target=mouseover,nodead,exists,mod:alt] focus
can you explain why you have
Code:
/target [exists,nomod]
and
Code:
/focus [target=focus,nodead,exists,mod:alt]
because [exists,nomod] refers to your current target...this seems to be irrelevant
likewise
/focus [target=focus,...] means set your focus to your current focus.

If I have this wrong, please enlighten me.
