How do you locate an exact spot on the work area?

Ok, I have figured it out one more time, maybe this time it will take.
It is a matter of terminology, work area means work piece not the area of what your machine can handle.
So if I have a 7x7 workpiece then that is what I define as work area. Then when I set xy zero it uses that as point of origin.
I am going to make a big sign and paste it so I see it when creating projects.
Guess I am getting old.
