Thank you for your answer. Ij you look at the 2nd photo (Tha black side is upside), it is exactly what I have done, but it does not work.
If you normally flip the keypoard, the keyboard does not work to protect involuntary touch.
Update: Just learned today that there is a bluetooth attachment that attaches itself on top of the connector on the keyboard that turns the Surface Keyboard into a bluetooth keyboard. Then you can put the surface anywhere else and save all the space.
