Network Toolkit uses standard zoom and panning actions which are already available in Google Maps. To pan around the map, left click on the mouse and drag the map in the desired direction. Release the left mouse button to stop panning (moving the map). You can also use the pan button to the left of the map to pan the map in the desired direction.
To zoom in and out, use the scroll wheel on your mouse while the cursor is over the map. You can also use the zoom toolbar to the left of the map or you can double click anywhere on the map.
Quick Tip: You can quickly zoom to street level for any outlet by double-clicking on the outlet map pin.
