Just start typing a class name in the box. It autocompletes for most class names, or you can hit "enter" and it will run a little Google search for you. Stackoverflow answers are thrown in just for grins.As you can see, this little page is super primitive, but in fact I use it constantly when I'm programming on iOS, just to avoid that molasses-like Apple interface. If anyone feels like expanding on this script or building a better version - please have at it.
