Middle wheel button

Well, I know this should be easy, but do any of you know how I can get the
middle mouse wheel to give me that cool pop menu that allows you to turn
layers on and off, toggle elevations and descriptions, etc.? I had it going
in C&G Intellicad 98, but now I can't seem to figure out how to do it in
2001! Thanks!
