I have the selection saved, I want to load another selection within while subtracting ? I tried the boolean methods, I searched the manuals, even AdobeTV for an answer, I know it can be done, I'm having a brain fart
I saved Selection 1 then made a new selection 2 and saved it. With no active selection I went to the channels palette and Ctrl+Clicked on selection 1 the Alt+Ctrl+clicked on selection 2. It that what you want.
