How to show all parents and subclasses of a class

Question

When I'm editing a Java class in Eclipse, when my cursor is over a class variable, I can do Ctrl+T to have a popup that shows all its parents and subclasses. What is the equivalent in IntelliJ?

Example:

Use|r user = new User();

The pipe is my cursor.

Not an IntelliJ IDEA user, but this blog post seems to indicate that in version 8.1.1 and beyond Ctrl+Alt+U will display the "Quick Class Hierarchy".
