HH_DISPLAY_TOPIC command
Opens a help topic in a specified help window.
If a window type is not specified, a default window type is used. If the window type or default window type is open, the help topic replaces the current topic in the window.

- For backward compatibility with WinHelp(), HH_DISPLAY_TOPIC and HH_HELP_FINDER provide the same functionality.
- A default help window contains only the Topic pane and is not a three-pane Help Viewer.
