Customizable Keyboard/Mouse Shortcuts

[MacGyver]

Would be nice to be able to make custom shortcuts without having to write a macro.  Or modify already defined shortcut keys/buttons.

In Visio 2007 I had my mouse configured (using X-Mouse Button Control) to go to the previous/next page using the forward/back buttons on my mouse.
In Visio 2010 I can't do that as the program has a shortcut for these buttons on my mouse to close the document
