+* Distance measurement
+
+Osm provides a simple distance measurement utility. In order to measure a
+distance, place or select a pin by clicking with the left mouse button. Then
+create one or more additional way points by pressing shift and clicking the 
left
+mouse button. The length of the track will be shown in the echo area. You can
+select the way points of the track and delete them with ~d~ or ~DEL~.
