+            the mark by the same value. Once the other key is pressed, the value
+            is divided by 2 (hence the name "binary") with every further press
+            of either key. Pressing '1' and '3' alternatingly divides the

+            place in a recording (for instance the beginning or end of a

             jump to the very beginning or end, respectively, of the recording.
