How to see Javadoc documentation on mouse hover in NetBeans?

Question

Is it possible, when you mouse hover on method/class so you can see Javadoc in NetBeans 7?

I want similar to Eclipse, when you just mouse hover on String

Answer 1

I know that in netbeans 8.0 you can hold down the ctrl button and hover over the class or method, etc. and the javadoc window would appear.
