Are you talking about the clips that flip. This is how it is done:
Select the clip. Select the Adjust Anchor Point tool which is the tool below the select tool. In the canvas move the anchor point over the the edge of the clip that you want the rotation to move around. Then select the Adjust 3D Transform tool or hit F1 and adjust the rotation of the X or Y to get the desired look. Hope this is what you where looking for.
