1.4 Point and Click, Double-Click, or Secondary Click

     If you logged in using the earlier steps, you know the basics of using the trackpad. To tell the MacBook Air what you want to do, point the on-screen pointer to the object that you want to  work with by sliding a finger over the trackpad. After you point to something, you tell the computer what you want to do with it. You do this by pressing the trackpad down to click it. This is referred to as clicking the trackpad. The number of times you click and how you do so determines what happens to the object you point at.
