The Help System is built into each of the CDE applications (and possibly other applications installed on your system). When you ask for help while using an application, the application displays a help window.
Applications can use two types of help windows to display help topics: a general help window and a quick help window, shown in Figure 3-4.
General help windows have a topic tree and a topic display area. The topic tree is a list of help topics that you can browse to find help on a subject. When you choose a topic, it is displayed in the lower portion of the help window called the topic display area.
Quick help windows are streamlined help windows. A quick help window has just a topic display area and one or more buttons.
