Save As Dialog

[Andy Choens]

How do I make the Save As and Open Dialog default to ~/Documents
instead of ~?  I really would prefer to use Documents for my stuff and
leave ~ for my digikam folder, my music folder for amarok, etc.

Any ideas?  I've googled this to death and haven't found anything. 
I'm sure I just need to change a file somewhere in ~/.kde but I have
no idea which one.  I looked into a number of files but I didn't see
anything obvious.

It's just a little thing, I know.
