Hello Kirk,
This is a follow up of a previous thread I wrote before your Bday !! I run OS 10,4,10 on a Power PC and G4 Laptop. Actually I didn't make myself clear enough, I would like to have a shortcut or key to do the opposite of the shortcut you mentioned: to show all BUT "color class none" images. As a photojournalist I spend more time on my laptop than my desktop and sometimes deadlines are tight, so I try to use key shortcuts as much as possible in my workflow instead of the track pad. After I edit my images I often have pink and red images, I would like to have a key that SHOW ALL BUT "color class none" images. The same way F3 shows only tagged images.
Thanks
Hugo Aubert
