How does the zoom toolbar work?

The 'Zoom Toolbar' is the set of blue push buttons and two magnifying classes on the right side of the browser window.The orange button indicates the current scale range.

The magnifying glasses provide incremental zoom in/zoom out. The blue buttons provide zooming to a predefined display area or scale. In some browsers, a ‘map tip’ describing the display area set up by the tool is visible when you pause the cursor over it.

Clicking a scale button will redarw the map to the selected scale maintaining the map's center.

Clicking on the magnifying glasses will move the selected scale up or down the zoom toolbar. Once the top or bottom of the zoom toolbar is reached, clicking the magnifying glasses will continue to zoom the map in or out by five percent.
