The Overview window displays the full extent of a layer (e.g., street edge). A red box on the Overview window shows the location viewed in the Map Display tab in relation to the full extent.
If the Overview window is not displayed in your user interface, select Overview from the View menu. This window may be docked or left floating.
To choose the layer to be displayed, right-click in the Overview window and select a layer. Only a single layer may be displayed in the Overview. Select a value from the Scale flyout menu to determine the scale viewed in the Overview window.
As you navigate the map on the Map Display tab, the red box in the Overview window will move to correspond to your current location in the map. You may manipulate the red box to change the scale and location in the Map Display tab. Make it larger to zoom out and smaller to zoom in.
