Steps to reproduce

1. Go to Edit > Preferences (or use Ctrl + P)
2. Change the Preset to Maya
3. Move the mouse pointer to the viewport area and hold Alt + RMB and move up and right.
4. Observe the issue

Observed result
The behavior is not like Maya, but inverted. With this preset, holding Alt + RMB and moving up will cause the camera to dolly in (go closer to the focus), but in Maya this action will cause the opposite, that is dolly out (go away from the focus). For Maya users this is very confusing and annoying. It downgrades the user experience using iClone. Currently there is no option to invert this behavior.

Solution
Invert the actions of holding Alt + RMB as explained above.
