You request information about a topic in a window by positioning the cursor over it and pressing F1 or clicking the right mouse button once. The help system then searches through the help files for information about the topic. If it finds the topic, the help system displays information in the Help window. If help cannot be found for a particular word or symbol, a message informs you that no information is associated with the topic. Sometimes a topic with the same name occurs in several help files. In such cases, a dialog box is displayed in which you can select the context of the topic.
