Like said above, no set interaction for maya.
I personally use a five button track ball, with macro on the 1 button for (Equivalent to the back button on the mouse) for undo, the 5 buttons ( Which is equivalent to the forward button) mapped to my space bar.
I used to have the middle mouse button mapped to the alt key, and just use my scroll wheel to zoom in and out, but i don't anymore, i've since adapted to using a Nostromo Speed pad N50 Game controller mapped out with all the keys i use on a regular basis ( q,w,e,r,f,g,x,c,v, shift ctrl, ect ect ect and a few extra macros, like ctrl+shift things like that )
I rarely actually use my keyboard anymore, Number keys for display, function keys on occasion and my insert key since I've been too lazy to make the shelf button for it again.

Just another idea of user setup if it helps any.
