Michael,
Most excellent! Thanks for the effort- that's just what I was hoping for, especially the zoom.
Now I'll be able to combine the zoom with my little grid spacing script,which should make that really useful (to me, at least). The other nav keys are great too, since I've got a few other cad programs set up to use the arrow keys for navigation - makes it much easier switching between apps. Thanks again, for 3d modeling MoI is well on it's way to being the app of choice for what I do -

Paul
