  67        The  function <STRONG>set_current_item</STRONG> sets the current item (the item on which
  68        the menu cursor is positioned).  <STRONG>current_item</STRONG> returns a pointer to  the
  69        current item in the given menu.
  70
  71        The function <STRONG>set_top_row</STRONG> sets the top row of the menu to show the given
  72        row (the top row is initially 0, and is reset to  this  value  whenever
  73        the  <STRONG>O_ROWMAJOR</STRONG> option is toggled).  The item leftmost on the given row
  74        becomes current.  The function <STRONG>top_row</STRONG> returns the number  of  the  top
  75        menu row being displayed.
  76
  77        The  function <STRONG>item_index</STRONG> returns the (zero-origin) index of <EM>item</EM> in the
