Topic Only View in HTML Help
The show/hide button in the toolbar pane allows users to add or remove the navigation pane. The writer can also define a window in HTML Help Workshop that does not include the navigation pane, or with the navigation pane hidden by default. Without the navigation pane, more screen area is available to display the help topic content, or for the application itself. However, the navigation pane helps users view where they are in the organization of topics, and quickly browse and access other topics in the table of contents.
