Using the D2000 HTML help viewer

By default, when you build a help system, your compiled help file (.chm) will appear in a window with three panes:

On the left side of the window is Navigation panel. It contains four navigational tabs: Contents tab, Index tab, Search tab and Favorites tab.
On the right side of the window is the Topic panel. It displays the selected help topic, or the default help topic.
The third panel is the toolbar, which is located below the help window title bar. Toolbar is placed below the window title and it contains several buttons.
