The following position-based selection tools are available only after you
  start a procedure that requires object selection (position-based selection is
  not available outside of a procedure):
 - Objects closest to the
screen

 Toggle on this tool to select only the objects closest to the front
  of the screen. This tool is toggled on by default.
 
If you toggle off this tool,

  allows you to cycle through all of the possible selections. Use the
  Next and Previous buttons in the
  prompt area to cycle forward and backward through all of the objects in the
  viewport that are possible selections; each object becomes highlighted in turn.
