You can navigate separately in the navigation and tool areas. When you navigate in one area, the other is not automatically updated.

For example, suppose you choose an include from an object list. This is displayed in the ABAP Editor. If you then double-click the name of a global class referenced in the include, the system starts the Class Builder and displays the relevant class there. The navigation area, however, still shows the object list from the program to which the include belongs.
Similarly, if you choose a different object list, there is no automatic adjustment in the tool area.
