Zooming in or out of the map helps you view a larger area or focus on a particular zone on the map. Listed below are the different ways to do this.
1. Click the + or - button on the left side of the screen. Clicking + will zoom into the map so you can focus on certain areas. If you want to see a larger portion of the map, just click on the - sign to zoom it out.
2. You may also use your touchpad. Just place your two fingers on it, then pinch in to zoom out, or stretch out to zoom in.
3. Or, use your keyboard and mouse. Press Ctrl then scroll up to zoom in, or scroll down to zoom out.
