Recap


                          The mouse is an important part of the computer.

                           It is used to draw pictures, play games, give commands and to point at
                         different things.
                           A mouse has two buttons and a scroll wheel.

                           Pressing and releasing any button of a mouse is called clicking.

                          Clicking the left button once is called single-click.
                          Clicking the left button twice is called double-click.
                           Moving the mouse while keeping the mouse button pressed is called
                         dragging.
