With this wheel, you can access basic 2D navigation tools; it is particularly useful when you do not have a pointing device with a scroll wheel. The wheel includes the Pan and Zoom tools.
The 2D Navigation wheel wedges have the following options:
Pan: Repositions the current view by panning.
Zoom: Adjusts the magnification of the current view.
Rewind: Restores the most recent view orientation. You can move backward or forward by clicking and dragging left or right.
