title: IDEA equivalent of Eclipse "type hierarchy" (F4)?
body: <p>In Eclipse, you can select a Java class and show the class hierarchy ("open type hierarchy" or <kbd>F4</kbd> in default bindings). It opens the "Type Hierarchy" view, which lists its base classes and the tree of its subclasses.</p>
  
  <p>I'm sure there is an equivalent in IDEA to get this information but I haven't found it yet.</p>
  
  <p><strong>What workflow is best in IDEA to quickly show the base classes of a given class?</strong></p>
  
  <p>Visualizing the subclasses is nice to have but less critical for me. In the editor, I can find the immediate subclasses easily via the "has subclasses" button on the left pane.</p>
