showing all cell referances

At the risk of sounding like a novice I have the follow question:

If I double click in a cell, Excel shows me all of the different cells referenced by my formula by using colored boxes.

Is there any way of doing the reverse of that. I would like to know all of the other cells that reference a given cell. I am going through a bunch of sheets that someone else created and there are cells that I have know idea where they are used or why they were created. I wish the they would've made some notes, but no luck and they no longer work here, so I am kinda up the creek.

Any suggestions to ease my pain would be appreciated.

Thanks in advance

Matt
