Tried this in Acrobat 9 Pro and it worked, but it doesn't work in Acrobat Reader 9.
Found some discussions this may require enabling with LiveCycle or LiveCycle Reader Extensions server.
If true, should the Quick Bar be updated on this page:
The document does need to be enabled with LiveCycle Reader Extensions for it to work in Reader. This is just one of a number of documentation errors that should be corrected.
Thank you George for the clarification.
