Hi,
Thank you for writing to Microsoft Community Forums.
I understand that you want to switch displays by assigning a shortcut. Currently, to switch between screens the available shortcut is Windows Logo key + P.
You may want to use your favorite search engine and look for an app that helps you in achieving this functionality.
However, we always appreciate our customer’s feedback, and your feedback and suggestions are very important to us. Hence, I suggest you to provide your valuable feedback and ideas in our Feedback Hub, where our developers can look into the requests and constantly improve the features of Windows.
Regards,
Nikhar Khare
