I'm trying to set a keyboard shortcut for Layers>Flatten Image to Cmd+F1. But when I try I get a message stating that Cmd+F1 can not be assigned because it is being used by the OS.
I'm using Mountain Lion (10.8). There is no way to disable that in the OS that I can see. Does anyone have any ideas how to get this keyboard shortcut to work in CS6
Hello, I did a quick search myself, and you might be out of luck...
