    MOUSE POINTER

                      Just as we use our fingers to point at something, we use an arrow
                      to point at things we want to select on a computer. This arrow is
                      called the mouse pointer.

                      When we move the mouse, the mouse
                      pointer moves on the monitor in the                                Subject: Wireless Mouse
