I want to write a program for computers with multiple monitors, where it would let you enable and disable the various monitors. For example if you had 2 screens, and you only wanted to use one at a time, it could swap back and forth between them. Or if you had a tv connected to your computer, you could swap to it or extend to it. Ideally from keyboard shortcuts. Windows lets you do this already, but only through multiple steps of properties windows and boxes.
I have a decent amount of programming language knowledge but I've never tried to do anything like this before and I don't really know where to even begin.
