Switching monitor layout

[shobo20]

Setup:
2 monitors connected to:

• a Win10 machine via DisplayPort and HDMI
• a macbook pro with Thunderbolt 2 to DisplayPort adapter and HDMI directly
  Keyboard and mouse connected to the Win10 machine

I would like to know if it's possible with Barrier to switch the keyboard and mouse between the Win and mac with a key combination regardless of which operating system is "connected" . Ideally, i would like to send to the mac a keyboard shortcut to display only on the built in retina, so i can have that screen visible while the 2 monitors are displaying the Win output.

The scenario i would like to achieve is:
While the monitors and K/M are connected to the mac, have it output only to the monitors, but before switching to Win output, a key combination to change the mac display to the built in,so it's still visible when i use the Win.
