When switching to another input on an external screen that you're normally using to extend desktops, you may want to set the MBP to mirroring to continue using it, but doing that switches the Color LCD to the resolution of the external screen, which in 4K retina mode makes things... small.
This fix requires Display Menu with the Pro features unlocked for scripting access.
Create Quick Action in Automator under "Utilities", "Run AppleScript". Make sure "Service receives no input".
Then in System Preferences, "Keyboard", "Shortcuts", "Services", give it e.g.
Fn+Cmd+F1as a shortcut, or, on a Mac with Touch Bar, you can customize the Touch Bar and e.g. in expanded view add the Quick Actions menu item, then it'll show up there.
