How to get to containing folder of a document?

Simple question about DT2:

When I have a document open in its own window - how can I get to its containing folder? (The GO menu is grayed out.)


You could either reveal the document (see Data > Reveal) or Command-click on the window’s title and select the desired enclosing group.

I said it is a simple question… Thanks for answering! I should have thought of this myself.
