Above a block of overridden methods leave a comment for which class they extend:

// ash::VolumeControlDelegate:

[bruthig, 2014/04/29 15:49:00]

Done.

+  virtual bool HandleVolumeDown(const ui::Accelerator& accelerator) OVERRIDE;
+  virtual bool HandleVolumeUp(const ui::Accelerator& accelerator) OVERRIDE;
+
+  int handle_volume_mute_count() const;

[jonross, 2014/04/29 14:42:43]

Overridden methods should come last. So these should be placed above

[bruthig, 2014/04/29 15:49:00]

Done.

+  int handle_volume_down_count() const;
+  int handle_volume_up_count() const;
+  const ui::Accelerator& last_accelerator() const;
+
+ private:
+  const bool consume_;

We don't really use const on class member variables. This one is actually set in
the constructor, so it could become a normal member variable.

For constants we defined them within the cc file in an anonymous namespace.
