I don't know if this is an all-inclusive list of them, but there seems to be:
1. The hanging clip you mentioned. Used when you ***** a model on your desktop to a new position then "drop" her. There seem to be 2 different hanging clips too, but I'm not sure if that is included in every model card.
2. A "drop clip" where she ends up standing up.
3. A "drop clip" where she continues to the floor and ends up sitting on the floor.
4. A clip where she starts with standing then sits down (similar to the "drop clip" above, but without her dropping from a hanging clip first).
5. A clip that starts with her sitting on the ground then stands back up.
6. A clip where the model walks to the left and stops walking.
7. A clip were the model walks to the right and stops walking.
8. A "Hey! I'm Bored!" Pay Attention to me!" clip. These vary from model to model, but are "cute" clips like the model is annoyed you aren't paying attention to her. She can seem like anything from "pouty" to "pissed off" at you. I personally like these clips. Some of the models are very good "actresses" in portraying their "annoyance" with you. ;-)
I think I got 'em all above, but may not have.
A quick way to see them all is to select a Full Screen Scene that allows ALL clip types to play (the designer of the scene would have had to create the scene to allow that). Then set the Nudity Level to "All Levels", and set "Progressive Hotness". For some reason, the above clips will tend to be (but not always) shown "out of sequence" at the start of the Full Screen Scene show, even though the clips above will almost always be a "Full Nudity" clip.
