You didn't say how long you've owned your 8080, but it took me about a month with my C-series camera to remember where things are when I needed them in a hurry...the method I use to remember is what main heading is the feature I want to change in...does it has to do with before the CAMERA takes a picture, does it have to do with what is done to the PICture after it's taken, does it have to do with the CARD, or with SETup of the camera (the guy with the wrench).
