Selecting files without opening them in nautilus

[José Alburquerque <jaalburquerque cox net>]

Hi. I have a simple question:  Is it possible to select a file in 
nautilus without it automatically being open if my mouse behavior is to 
open files on a single click?  Right now I'm running GNOME 2.8 (using 
CentOS 4.3) and I love the great behavior of my desktop, but I'm 
wondering if there's some mouse command or something that I'm not aware 
of to select a file without it opening under the premise that my files 
open on a single click.  Any suggestions?  TIA.

Sincerely
Jose Alburquerque
