Then you can assign a keyboard shortcut to make the action run. The complicated method involves writing an action with an Insert Menu item to the saved profile settings.
However, if you save the proof setting when no image is open, select that settings, then when you open an image and click command (mac) or alt (win) and the 'Y' key you can use the keyboard short cut to turn soft proofing on/off. If you save the images in sRGB, the slideshow should run fine and I don't know what or why you'd soft proof in the first place.Īctually you can (but it is very complicated). A proof setup is used to simulate output to a printer more or less. I'm still confused by why you need to do this. You can save a customized proof setup but you must select it for it to invoke.
