Cannot access the frame properties in Pan and Zoom when applying to a video clip

PROBLEM:  We cannot access the properties for a frame in the Pan and Zoom window in order to change the Pan Duration or Hold Time for frames in a video clip.  How do we access these properties for a frame?

BACKGROUND:  We are working with a video clip, not a photograph, and are able to create the frames we need, at the locations we need, using the Pan and Zoom tool.  The manual infers that we can change the Pan Duration or Hold Time for any frame by clicking on the respective elements in the frame.  Unfortunately, we cannot seem to bring up the frame properties dialog by either left or right clicking with the mouse.  Nor can we find any other way to access these settings for the frame by clicking on the Timeline markers.  Another anomaly is that the manual indicates we can re-arrange frame markers on the Pan and Zoom timeline by dragging the marker.  When we click on the timeline it simply resets the Current Time Indicator (CTI) and does not allow us to drag the frame marker.

As new users, we thank you for any assistance!
