Toggleing Owner and Permissions in File Browser?

[William Case <billlinux rogers com>]

Hi;

What are the commands to bind to an accelerator key so that I can toggle
or turn on and off quickly ownership and permissions under the names of
files?  Of course it can be done by Preferences --> List Columns, but
all suggestions on how I can do this with a single key stroke for a
quick look at the owner and permissions attached to a file will be
gratefully received.

Regards Bill
