To zoom the view with a single click
Note:You must enable incremental zoom when using the Full Navigation wheels, or a mini View Object wheel. For the big View Object wheel, the incremental zoom is always enabled.
The magnification of the model is increased and you are zoomed in closer to the model. If you hold down the SHIFT key while clicking the Zoom wedge, the model is zoomed out; you can hold down the CTRL key to zoom in.
