GenMAPP utilizes some Windows-specific features to navigate the various functions of the program. In particular, a right mouse click often must be used to activate user interfaces for critical functions of the program. For example, a right-click on a gene will open the Gene Finder window, a right-click on a label will allow you to edit the label, a right-click on a line tool will open a Line Data window, and a right-click on other objects will allow you to change the color of the objects.
