Open in context?

If I look for a particular file in a large project, a list of files comes up. I seem to remember there’s a way to select the file you want (or nearly want - it’s something on the same subject) and show it in its place in the project, so you can see the nearby files. Is there? And what is it if so?

(Sorry, the name here should be show in context, not open in context.)

Ack, I’m an eejit - it’s Reveal in Binder in the Navigate menu.
