None that I am aware of. And I'm looking at the complete list of keyboard shortcuts in the appendix of my book.
Only thing that comes to my mind is Dbl-clicking on the Clip in the Timeline, which will open that instance in the Source Monitor. The In & Out Points will appear there.
In the Project Panel, you have the "master" Clip, and not the instance, that appears on the Timeline.
Maybe someone else will have a keyboard shortcut, or other quick method.
Thanks, Steve and Hunt.
