question on nautilus

[Paul Allen Newell]

I am trying to change the default text editor in what I think is 
Nautilus from gedit to vim. All the info I see online either addresses 
it for another Linux flavor and/or seems to imply that I should see Gvim 
as an option when I go into file->preferences (which I do not). I 
spotted one link with seemed to imply that it might be something to the 
effect of "/usr/bin/vim @1", but not enough for me to trust. I tried 
searching in ~.local and ~.gnome* and ~.nautilus for any reference to 
gedit thinking I could change a file, but found nothing.

Suggestions? (and that includes a scolding for "why didn't you look in 
the obvious place?" which is not obvious to me)

Thanks,
Paul
