+1 for @adamjimenez. Visual Studio behavior is:

- Single click: select the fold, so you can delete it or something.
- Double click: expand.

Also what I really like is giving an indicator what is going to be folded. See [screenshot](http://fotopocket.nl/fpimages/2011/12/14/92ddb5f9069d2c201cea8aecec76c157/Screen%25Shot%252011-12-14%25at%2511.03.08%25AM.png).
