Very Cool that this is finally implemented again 1:04 (bluetooth) keyboard. The clear usecase is: If you are sketching something (like an artist) you want the have the pro in studio mode but sometimes still need the shortcuts on your keyboard. I used to work for microsoft as an ambassador in the stores. I remember this was also a thing during the surface RT and surface 2 times.
This is a feature that we love too - like you say, keyboard shortcuts can be very useful when drawing with the Pro in Studio Mode! 41 hours of battery life too 😍
