Most applications have a Help menu that contains commands for requesting different types of help such as an introduction, application tasks, or reference information.
A typical CDE Help menu includes these commands:
Overview—displays the home topic for the application. The home topic is the first topic of the application's help topic hierarchy.
Tasks—displays task instructions for most operations performed with the application.
Reference—displays reference summaries for various components, such as windows and dialog boxes, menus, and application resources.
On Item—enables you to click an item in any window of an application and view a description of the item.
Using Help—provides help on using the help windows.
About Application—displays the version and copyright information for the application.
Applications can include additional choices. Also, non-CDE applications may have different commands in their Help menus.
On Item help is interactive. It enables you to move the pointer to a specific item (such as a menu, button or dialog box) and click the item to display its corresponding help.
