Checking calculation status...
• Use ESC key to stop drawing or modification of polygons.
• With the selection "Polygon" active (radio button is on), existing
polygons can be modified by clicking and dragging vertices
or borders.
• De-Select option draws "negative" polygons for subtraction. 		Shortcut keys:
• Use  ukey to remove last drawn polygon point.
• Use  Delete key to remove selected polygon.
• Use  rkey to remove selected polygon vertex.
• Use  dkey to densify selected polygon(s) in map projection.
Notes:
• "Densify" causes saved polygons to have much finer spacing of vertices, so that chronologies in polygons remain in polygons regardless of change in map projection.
