The work that you had done since the time of your last save will be lost. There are two types of help available to you. Hold the mouse button down and move down to Show Balloons, release the button. When you move your mouse over an item, it will now show a small balloon explaining each menu item. To turn the balloons off, choose Hide Balloons from the same menu.
Some applications also provide a Help feature in addition to the balloons.
Release the button and a dialog box should appear. Choose the topic you need help with and click on it. To close the Macintosh Guide click the box in the upper left hand corner. To quit an application, choose Quit from the File menu. When you are finished using the Mac, make sure all programs are closed.
