Opening a parent window in spacial mode

[Chris Egan <chris limewolf com>]

I've been playing with nautilus 2.5.8, using spacial mode. I've been
using a similar system for many years (RISCOS and then ROX under Linux)
and I think I'm likely to switch to nautilus (hey I can use that handy
cdwriter extension and very nice it is too!).

I'd like to know how to open a parent directory, when in spacial mode?
Assuming there is a parent directory, I'd have thought some sort of
shift/ctrl/alt/+close would open it? Am I missing somthing, or is there
no 'quick' way to open a parent directory currently?

Chris.
