Click the orange 2 below. Here is how

Rest the heel of your writing hand on the desk in front of the mouse (we assume right-hand) Hold the mouse between your thumb and ring and little fingers Slide the pointer of the arrow onto the orange 2--Don't turn the mouse. When the arrow becomes a pointing finger , hold the mouse very still. Lightly click the left mouse button with your index finger (see the picture at right). If the next page doesn't appear after you click, you aren't holding the mouse still when clicking.

    Click It ->  2  <- Click It
