There are three basic ways to navigate around a map within the Viewer:
- Zooming
- Panning
- The Home Button
Zooming in or out of the map will make the contents of the map bigger or smaller within the Viewer.
If you are using Windows Operating System, and have a mouse with a scroll-wheel (like this one), you can simply use the middle mouse wheel for zooming in and out.
Otherwise, you can use either the zoom in or out buttons at the right edge of the Viewer...
...or you can zoom in by double-clicking with the left mouse button. If you are using Windows Operating System, you can zoom out by double-clicking while holding down on the control key (Ctrl) on your keyboard.
Panning is the vertical (up/down) or horizontal (left/right) movement of the map within the Viewer.
To pan around in a map image you can either use the directional pan buttons at the right edge of the Viewer...
...or you can use your mouse by clicking and holding down on a spot with your left mouse button and then moving the mouse to drag the image in a given direction.
Located in the center of the directional pan buttons (see above), clicking the home button will zoom and position the map so that the whole thing fits within the Viewer.
