Centering the default Main Camera using the Unity IDE GUI

This is just for convenience during develop-time (no need for script) - is there a button or some sort in the IDE to easily center the Unity camera to the only cluster of items in the hierarchy?

You can select an object (or objects, probably), give the scene view focus (e.g. by moving the mouse over it), and then press 'F' to center/focus the scene-view camera on that object (or those objects). Is that what you're looking for?
