Keith, we can copy and paste:

 Click picture
 *With ControlKeydown we can*:
  *  see coordinates of the centre of the cursor in the bottom right of the
window.
  * copy and paste the coordinates of a series of clicked points:
click on a series of points (they be marked by points); press C to copy the
coordinates; paste the list of coordinate
  * copy coordinates along a trace:
  click on the picture to start the trace; move cursor on picture (points
    will be displayed along the track); press C to copy the coordinates;
paste the list of coordinates.
