Using navigation mode, you can clearly present the chronological or hierarchical sequence of a model.
Procedure
Open a process model, for example, an EPC, or a hierarchy model, for example, a function tree.
Right-click the start event of the EPC or the top function (root function) of the function tree.
Activate the View tab bar.
Click Hide/Show > Hide all objects except for the selected ones. Only the selected object remains visible.
Press the Ctrl + E keys to show the objects connected to the selected object.
The objects are shown in their chronological or hierarchical sequence as you discuss them in your presentation.
