Shortcut Show Project Window?

I really like to have multiple Mixers like Cubase offers. I have them on F3 (standard Mixer), F2: Mixer 2, F4: Mixer 3.
Is there a possibility to make a shortcut that shows the Project win. again?
The situation is: I can switch between e.g. standard Mixer & Project with F3. When I then open my 2nd Mixer with F2 and my 3rd Mixer with F4, I have to close them all to come back to the Project Window. It’s not a good workflow like this. I would like to have one Key to come back to the Project. Is that possible?

It’s the Key Command, Project: Bring to Front

Hey Steve, thanks!
this helps me a lot! I have it now on F5.
