Centering, and other tools, in Inventor?

-To Zoom you hold F3 down
-To Zoom all there is NO hotkey or shortcut you simply have to go to the button that looks like a box with four arrows pointing from the inside to the outside edge.
-To Rotate you hold F4 down

There are very few hot keys in inventor. I think that this is the biggest down side to inventor. The fact that you have very limited abiltity to customize your user interface is a bad idea.
