-the command ``distance``.  You will be asked to click two points.
-When you click a point, a blue dot should appear.  When you click the
-second point, the distances (in nanometers and piconewtons) will
-appear on the command line.  You can use ``delta`` if you prefer,

 Hooke automatically adjusts the position of the clicked point to the
 nearest point in the graph, so you will be always measuring distances
 and forces between points in the graph.
