Hasta La Motion!

I am following the tutorials on page 60 of the “Introducing Maya 2011” by Derakhshani. I am using a MacBook Pro 17” and he says to use the “Home” button on the Mac to activate the pivot point so that I can move the pivot point from its origin of (0,0,0) to the center of a sphere object. However, there is no dedicated “Home” key on the MacBook Pro. Instead, the Mac help literature says to click the Command button and left arrow button at the same time to activate the “Home” key. This does not activate the pivot point. Is there another way to do this?

Sincerely,
Gregory
