Hello, I'm playing two accounts on the same computer - my main, and then an alt priest whom I command by voice. I'm trying to write some macros for the voice commander, but unfortunately I'm not to good with them...

I was wondering if anybody would be so kind as to tell me how I would write a macro that basically tells my priest to use Smite on my target? I'm having trouble with the target portion... how do I write that? so that my priest attacks my target?
