What is hotkey for removing interface from C3C?

[Slax]

I recall reading (in a forum thread) that there was a hotkey added for removing the interface graphics. Now that I have the game, I'd like to know what it was. I can't seem to find it mentioned in any official docs.

What is it?

Tanks.

The key is Del.

That's right!

Thank-you.
