[OSM-newbies] Moving polygons in JOSM

[Bob Hawkins]

I see now that I can move the polygon simply by clicking part of its 
perimeter to select it, then clicking again and dragging.  I often fall into 
the trap of mistakenly believing that an operation is conducted from within 
a polygon once it is selected.  I am grateful for the information regarding 
the middle mouse button; so much is inherent in JOSM and I continue to learn 
and add to my knowledge through the mailing lists.
