How to find a file in the Xcode navigator

I'm looking for the location of a file in my Xcode navigator. I know where the actual file is in my directory, but not what group it has been added to in the Xcode group structure. In other words, I can't find the reference to it in the navigator. How can I find it?

I'm using Xcode 4.6.1.

Solution

Enter the files name in the bottom bar (search field) of the Project Navigator (on the left side), press enter => there it is ;-)
