Editor bug: "fps keys" don't work anymore

In the beta of unity 3 I could right-click and then use WASD to move the camera. This is called "FPS keys" in the Edit->Preferences screen. But it doesn't work anymore. It doesn't do jack no matter what I set it to. Does anybody know where it went?

You must be sure to be in perspective mode. Click on the Box at the Scene Gizmo to go back to perspective mode.
