              * before going to the onkey method, list should have scrolled (except when and issue occured)
              * so, if we are going down, the last visible item has to be focused item +1 (focus is done after the function, when  return false)
              * if last visible item == selected item even if this isn't the last item of the list, then the list won't scroll anymore.
              * So we scroll it manually.
