Sorry if this question has been asked before, but using mages as an example:
Is it possable to use this set up so if I press '2' it case a fireball at the target of my current window but if I press 'Shift+2' it casts a fireball at its current target. So if I want to kill single targets it atacks my current window target or if I'm pulling an AOE group I can have each mage target a different mob so when I shift+2 it cast a fireball on a different target so no one mage gets agro from each mob.
