I'm climbing a wall in the first level of Psychonauts and can't figure out how to get Raz to turn around while hanging from a bar, so that I can jump to the one on the left.

This is a little embarassing, because I feel like I've tried everything:
- Left and right make me swing around on the bar.
- Up and down make me shimmy from end to end.
- Spacebar jumps off (in the wrong direction)
- Cancel lets go of the bar.
What button do I press to make Raz turn around and face the other direction?
