The shift function for the camera does not work with my mouse (sorry I know I'm not using the term maya uses but its the alt + middle mouse button one). I have a mousewheel...maya zooms in and out when I scroll it but when I press it nothing happens. So I have zoom with alt + right mouse and with my mouse wheel and I can't shift at all. Is there any way I can change alt + right mouse to shift instead of zoom.

I've looked everywhere I could think of and can't find any way to change it...it's not under the hot key settings.
