Handed Crotch gesture:
To do X-Pac’s one-handed crotch gesture (miming receiving head from someone) simply set both bases to Dancing no. 4

Goldust:
To do the infamous Goldust wiggle, set Base #1 to Other 12, and Base #2 to Others 8

Inappropriate Hand "Motion"
Okay, this is a little warped, but someone requested it.

Requires: Fingers 014

First off, select Dancing no. 4 as your bases.

Now, go into Modify -> Upper. Go into the fourth slot along and select pose no. 232. Then leave two spaces and select pose no. 222. Keep going as long as you want, but for a natural finish leave a few blank near the end. I left 4 in between my last pose and my last (default) frame.
