The keyboard and mouse on a Mac are slightly different than on a Windows machine.
As mentioned in the CD burning paragraph, the keyboard has an eject button located in the top-right corner of the keyboard opening and closing the CD drive.

Also, the keyboard has an Apple (or Command) key.
This key is used much like the Control key on a Windows machine. Many shortcuts in programs on a Windows program will work with the Apple key on the Mac. The Control key is used differently on a Mac. One way it is used is in conjunction with the mouse. The mouse only offers one button as compared to the two plus buttons on a Windows machine. The Control Key can be pressed down with the click of the mouse to show menus and many other functions common to the right button on a Windows mouse.
