Can someone tell me how to search within a project for anywhere a particular effect is used?  If that's possible.

I have a strange occurrence where my entire comp went to black and white and for one brief second, I saw a pop up indicating some memory leak or something associated with VC Color Vibrance.  

Fortunately the project was just completed and rendered BUT, before I shelve it, I'd like to remedy that.

Thanks ahead.
