MCU PRO: How to set From and Thru Times

 
When I attempt the below procedure, the M1+Rewind step moves the selection to the end of the file instead of selecting a measure at a time.  The M1+FFWD behaves similarly, except it moves the selection to the beginning of the file.  Suspect I'm doing something stupid but can't figure out what.  Any help appreciated!
 
Here are the steps from the help file:
To Set From and Thru Times
Move the Now time to where you want either the From or Thru time to be.  Press the Select button so that its light is lit.  Hold down the M1 button while you press either the Rewind button or the Fast Fwd button to set either the From time or Thru time, respectively. Note: Use the Select button that's in the Transport Mode section, not one of the Select buttons that are in track strips.
