+the 'originator' and the things you want to set. They also accept a
+symbolic argument as first and a float as second argument. The symbolic
+argument is used to uniquely identify the 'thing' that is managed.
+The second \, float arg serves the communication with the 'originator'.
+Normally you use \$0 here.;

+is currently stored in the 'originator' state. So you normally 'cross-wrap'
