[Solved] get id of current page in the manager to use in a TV

I am looking to create a snippet to use @EVAL to list values in a TV.

My problem is I want to manipulate the children of a current document. How can I retrieve the ID of the current document I am editing via the manager (not the frontend)

Thanks
Brian
