How do I find a Placed Keynote?

[Miner]

I can't seam to figure out how to find a placed Keynote.  I want to ensure I'm not labeling two different objects with the same keynote label.  Visually I can't locate the keynote on my plan so I don't know if it's hidden or note used.  Before I use it for a new object I want to make sure it's not already being used.  

Does anyone know if you can search for a placed keynote?

Thank you
