Could you please change the way you navigate in the scene so its more similar to Showcase and Maya, or add an option for a different way to navigate. It´s very difficult and time consuming to align the camera in Publisher. I see how slow our CAD-guys are working in Inventor which has the same way of navigating as Publisher, compared to how I work in other 3D-applications such as Maya and Showcase. Now when I started to use Publisher I know why they are struggling with the navigation.
My suggestion is:
Alt+LMB = Orbit / Orbit the camera around the object constraining the Y-axis so that it is always vertical.
Alt+MMB = Pan
Alt+RMB = Dolly / Moves the camera back and forth in the cameras Z-axis. Zoom should be a numerical setting in the camera or another keyboard shortcut + RMB.
F = Frame Selected / Moves the camera to the selected object and sets the Orbit Center the center of the selected object.
