Cool, didn't know about the #'s being hot keys... But I'd like to mention that when I create some boolean objects for later use, that I like keeping my initial object at the world center. It makes positioning things relative to each other easier, especially when symmetry is needed. So whatever you have on one side is positioned using the negative value for the other side (when using absolute positioning - that little "A" box floating near the selected item. This comes in handy if you're trying to get things to mesh perfectly.) Also don't forget that some things sometimes still don't look right until you use the Flip command on the scaling pulldown menu.
