Help Navigation

The topic tree shown in Figure 1-4 is an outline of topics in the current help volume. The first topic at the top of the list is the home topic, or beginning of the help volume. An arrow (=>) points to the current topic and shows the user's location in the help volume.

To display a help topic, a user selects a title in the topic tree or a hyperlink within the topic display area. The user can browse the outline of topics by scrolling the list and then select any topic. Navigation commands enable the user to return to previous topics or to the beginning of the help volume.

Help Navigation Buttons

The general help dialog includes three dialog buttons: Backtrack, History, and Index. These features are also available as menu selections.

When using the Help Viewer from the desktop Front Panel, the general help dialog includes an additional dialog button called Top Level. After exploring different help volumes, a user can select this button to return to the top-level of the desktop browser help volume.
