Focus (carret?)

Hi, I am full of questions tonight! I vaguely remember somone saying something about a carret object used to set the focus of a layout, but I don't remember enough to use it. How do I set the Focus? Thanks!! Ammon Everybody's singing the windows tune: supercalifragilistic-XP-aladocious even though the sound of it is something quite atrocious If we buy it fast enough, then microsoft will own us!
