While viewing pics on Windows Photo Gallery, my ex once tried this shortcut and could instantly see the image as it was taken (ie. before any photoshop/other program adjustments were made). It didn't pop up in a new window, it was the same one and I *think* when you release the keys it goes back to the newer settings, post-photoshop. Anyone knows what it is? It's been bugging me for ages so I'd appreciate any input.
