Thanks, @spikeyxxx, I’ve just seen that Kent is in “Edge Select Mode” of the same Blender version when demonstrating “Pick Shortest Path” from 4:00 to 4:16 in his video. And it works in my Blender 2.66.1 copy as well as it does in “Face Select Mode” like you described it. Only “Vertex Select Mode” doesn’t offer this possibility. Blender 2.67 behaves the same but Blender 2.71 allows “Pick Shortest Path” in “Vertex Select Mode”. I suppose that this has changed with the transition to version 2.70.
