This tool allows one to easily hide or display information grouped in layers. When it is selected, a window containing a set of options will be displayed. These hide or display (i.e. they change the state) the relevant layer groups.
Clicking the right mouse button displays a drop-down menu of information on the points. The visibility of each level of points can be changed separately, or that of all points at the same time. The information disappears with another click on the right mouse button, leaving the window a smaller size.
Additionally, one can customize the way points are viewed. This can be by attributes, point types, levels, etc. In order to do so, the Points > Modify Points > Change Format command should be executed.
