A user can request help in several ways. Most applications provide a Help menu and Help key as well as Help buttons in dialog boxes.
Within most applications, the primary way for a user to request help is by pressing the help key. In recent years, the F1 function key has become a defacto standard help key for many workstation and personal computer products.
The CDE Style Guide and Certification Checklist recommends the use of F1 as the help key, and the OSF/Motif programmer's toolkit even provides some built-in behavior to make it easier to implement the help key in OSF/Motif applications.
Some computers provide a Help key on the keyboard.
The Help menu is a common way to provide access to help information. OSF/Motif applications provide a Help menu, which is right-justified in the menu bar. The CDE Style Guide and Certification Checklist makes recommendations regarding the commands contained in a Help menu.
Many dialog boxes also provide a Help button to get help on the dialog. The CDE Style Guide and Certification Checklist recommends that choosing the Help button in a dialog box be equivalent to pressing the Help key while using that dialog. Exceptions should be made for complex dialogs, where help on individual controls within the dialog box is appropriate.
