Walkthrough Mode
Display > Walkthrough Mode
 

Description:
   
    The Walkthrough Mode (Display > Walkthrough Mode) option, when checked on the menu, enables a separate set of camera controls which mimic a first-person perspective. Rotation occurs around the camera rather than around the manipulator, and zoom and pan move with different speeds.


Notes:

-This option affects all viewports, not just the active viewport.

-The speed of zooming and panning in Walthrough Mode can be edited in the Display Options (Options > Display Options...) dialog.
