While using the Walk Through controls, there are several options available on the local menu and Inspector Bar.
Undo Move: Returns the view to the position in which the current mode was invoked.
Straighten: Returns the view to a level orientation.
Discrete Movement: Limits camera motion. When on, the camera will only move when the mouse is moving.
Continuous Movement: Allows the camera to move as long as the left mouse button is held down. The camera movement will be in the direction the mouse was dragged. This is the default option.
Camera properties: Opens the Camera Properties window. See The Camera
