<p>This example demonstrates a couple features of the Navigation
control. The Navigation control controls most map dragging, movement,
zooming, etc. In this case, we have a demonstration of how to create a
navigation control with no zoom wheel action, which can then be enabled
or disabled by the user.</p>
