Using Your Mouse
The easiest way to operate your computer (especially if you can’t type worth
beans) is with your mouse. Most mice have two buttons; some mice have a
wheel between the buttons. The mouse button on the left is called the primary
mouse button. The mouse button on the right is called the secondary mouse
button, as shown in Figure 1-3. In a nutshell, you use the primary (left) mouse
button when you want the computer to do something. You use the secondary
(right) mouse button when you want to see your options before you do anything.
