Windows 7: .exe file that alternates "Computer Only" and "Projector Only" options

Is there an .exe file that alternates "Computer Only" and "Projector Only" in display options?

My laptop is hooked up to a monitor on my desk, and I use them both but not at the same time. So either I use "Computer Only" or "Projector Only" options.

I do know tapping Windows+P few times would work, but yes, I'm being super lazy here.

I'd like to know if there is a way to generate, if not existing already, an executable file that alternates between those two options so I can set one of my "hotkeys" on my keyboard to the exe file, so that I can just click the key.

Thanks in advance!
