HH_SAFE_DISPLAY_TOPIC command
Opens a help topic in a specified help window, and disables all shortcuts in the current process. Shortcuts will remain disabled as long as the calling process is active. This command can be used in place of HH_DISPLAY_TOPIC.
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.
