I've set my Print key to Take a screenshot of an area, but every time I logout and login it changes back to Take a screenshot (of full screen) without unsettin the old one ?! and saves the full screen until I change it back. How can I prevent this?!
Edit: sorry, my first explanation was badly understandable, I will try once more: I assign the Print to the area screenshot. In that case, it prompts window saying that it is already assigned to fullscreen screenshot, I say OK. Then, I logout and login and Print is assigned automatically to fullscreen screenshot and without overwriting the area screenshot
