Toggle to show hidden geometry as hard lines

[unearthed]

Is there a way to toggle hidden geometry to un-smoothed, hard lines?

like this:

I am thinking Make your selection. Window>Soften Edges> Move the slider bar. If you mean a script for this, I would have to look around.

Thanks,
I didn't know about that />bangs head on desk/ (pity the slider doesn't remember it's previous state).
