By holding the mouse pointer over any point on the map, you can zoom in or out by rotating the mouse wheel back and forth. On the one hand, we can see new details, and on the other hand, we can separate our close objects. The center of the zoom will be the current position of the mouse pointer on the map.

You can also zoom in and out using the + and - buttons in the lower right corner of the map. The focus point will then be the center of the map.
