Can I see interfaces in Eclipse's type hierarchy view?

Question

When I check the type hierarchy of a class that is derived from an interface in Eclipse, it doesn\'t show the interfaces. Is there a way to configure Eclipse to display the inte

CTRL-T is what you want.

Highlight the name of the class in the editor, hit CTRL-T twice. This will show you the supertype hierarchy in a little popup.

But wait, it gets better. Go to your interface. Put your cursor on a definition. CTRL-T (once) will show you all the classes that implement the interface. If you select one of these classes in the popup, it will take you straight to the implementation of the function you had your cursor on.

There, navigation between interfaces and their implementations just became a whole lot easier. Since I discovered this, I hardly ever use the Hierarchy view anymore.
