<p>In response to user input from a computer pointing device such as a track ball, activation of an icon causes at least one pair of adjacent opposing scroll icons such as arrows to be dynamically created on opposing ends of a display screen. Subsequent selection of either of the arrows causes scrolling of contents of a window in a corresponding respective one of a pair of opposing directions. Required conventional pointing device movement is minimized when alternate scrolling in opposing directions is desired due to the dynamically created arrows being adjacent, whereby conventional traversal of a cursor over large display screen distances between opposing non-adjacent arrows is thereby avoided. In an alternate embodiment, space-apart scroll icons point in opposing directions, whereby activating either arrow dynamically creates an adjacent opposing arrow, thereby completing the arrow pair necessary to scroll in either direction. <IMAGE></p> |
