Hi ndrakey, sorry no there is nothing set up for using a different key in place of the Alt key for view navigation methods like Alt+left mouse for orbiting the 3D view. You could try the system utility Tom mentions above, or also the Alt key navigation is actually a secondary navigation method for MoI that is set up just to be compatible with how several other animation type applications work. There are several other ways to do navigation aside from that, like just right drag in the 3D view to orbit with no keyboard key needed at all.
