Ojbect Hierachy - How to find where an item is used?

Unity Engine
1

I was going through the CarTutorial
and wanted to find where the
SoundController.js was used.

Is there a project hierarchy menu option in the Unity Editor that
will show all the objects/etc that use an item?

Type it into the search box (you can also search name, type, or both).
