How can I switch from computer to TV and back more easily?

[Windows Central Question]

I switch from my computer screen to my TV about ten times a day. The standard method is Windows key + P. But when I do that, I always have to choose between four options (computer, TV, both at the same time with same image or half the display on each) which is slowly getting on my nerves. I would really love to have a key that would swap directly from TV to computer and back without so much trouble each time. Is it possible to customize it?
