(11) Online Help

You can get help on Maple commands and concepts in various ways. These are the main methods:

• Context-sensitive help: Place your cursor on a word that you want more information about. From the Help menu, choose Help on word (where word is the word the cursor is on), or hold down the Ctrl key and press F1.
• Help browser: The help browser appears at the top of most help windows. (For example, from the Help menu, choose Introduction , and look at the top of the window.) In the first column of the browser, click on the general subject that interests you. If the topic name you choose has subtopics, the list of subtopics appears in the second column. Subtopics that can be subdivided still further display a list of sub-subtopics in the next column, and so on, up to five columns. When you have found the specific topic of your choice, click on the topic name. The help page for that topic appears in the display area of the help window, below the help browser.
• Topic search: From the Help menu, choose Topic Search . In the dialog box, type in the first few letters of the topic that you are interested in. Maple displays the matching topics in such a way that you are likely to find the help page you need near the top.
• Topic name: If you know the name of the help topic that you want to read, you can access the help page directly from the worksheet by typing ? name . For example, type ?plot at the command prompt to open the help page on the plot command.
• Full text search: From the Help menu, choose Full Text Search . In the dialog box, type in the word or words that you want to search for. Maple displays the matching topics in such a way that you are likely to find the help page you need near the top.
• History: To revisit any help page that you have seen in your current Maple session, from the Help menu, choose History . From the list, select the topic to revisit.
