3.4. Navigation pane

The navigation pane is to the left of the content pane & has several different tabs in it. These include Contents, Index, Search, Favourites, History (empty), Author (hinted at in htmlhelp.h, but currently can't seem to get it) & custom tabs.

The Contents tab is a tree structure of titles. Each title may contain other titles and or link to a topic file. It is used by authors to list all the contents of a help file.
