arrow key
     
         One of four keys on a {keyboard} marked with arrows
        pointing up, down, left and right.  The arrow keys are used
        for such things as moving the {cursor} in a text document, for
        moving the {input focus} between the fields of a form or
        sometimes for scrolling a picture.
