About commands
The HTML Help API supports a set of commands (uCommand values) that enable you to access functionality programmatically.
The most basic of the commands is HH_DISPLAY_TOPIC, which enables you to open a compiled help (.chm) file in a specific help window and display a specific topic within the help file.
