+On Android devices, use the Android Back
+button for "cancel", "discard" or "back" actions. For example, when

 == Recording dive locations using GPS.
 
 The fact that most smartphones have GPS facilities allows one to record
 the locations of dives. One can take the smartphone on the dive boat
 during a dive and locations will be automatically recorded at regular intervals.
+These locations can then be applied to dives in the dive list. Here is how it's done:

 GPS position that falls within the dive period of each dive. This results
