[PyMOL] select buried water molecules

Dear PyMol community,

During analyzing the water structure of a protein I was wondering if PyMol
is capable to select buried water molecules. Since the surface waters occupy
clefts it would be nice to see if there is a regular distribution inside of
the protein as well.

So is it possible to make a selection of buried water molecules?

I imagine something in a way like 'water without distance to
surface-object'. But so far I didn't have yet such a deep dive into the
sophisticated selection capabilities of PyMol and would be lost here. The
problem I see arising would be that the surface object is present (as
residues) even in protein's interior and make a correct selection
impossible.

Greetings,
Bartholomeus
