Navigation Wheels
You can choose from several different wheels. Some wheels are designed for
2D navigation while other wheels are better suited for 3D navigation.
2D Navigation Wheel
The 2D Navigation wheel is for basic navigation of 2D views.
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.
