This article provides step-by-step directions on how to pan, zoom, and toggle your downloaded SuperQuads in the TOPO! Explorer application. This differs somewhat from the functions found on the website.

3. To pan around the map, select the Pan Tool, from the top tool bar. Simply hold down the mouse button and either push or pull the map in the direction you wish to travel.
4. To zoom in, you can either double-click the mouse button in the place you wish to zoom, or click the Postive Magnifying Glass found above the Zoom Level Display Bar in the top-left corner of the map display window. Note that a blue bar shows which level you are currently on. You can also select a level by clicking on a particular level bar, or by sliding the blue current level display bar to another one of the 8 bars.
5. To zoom out, click the Negative Magnifying Glass icon, or click on one of the lower map level bars.
6. To toggle between TOPO | Aerial | Hybrid views - locate the the slider bar in the top-right portion of the map display window. Place your cursor over the blue current display icon, hold down your mouse button, and slide the icon to the left or right by moving your mouse. Release the mouse button to stop at a particular view. Note that in the application you can toggle seamlessly between any of the three views, whereas on the website you can only choose from one of the three preset options.
