The map area that is visible in the active graphical view, may be adjusted in different ways as to automatically capture all the objects in the current changeset. For example highlighted objects (as a result of a trace), or selected objects.

 

This means that the zoom position is adjusted so that all the objects that have been created or edited in the changeset fit in the active view. If the changeset is empty, the error message Change set is empty is given in the status bar.
