keyboard layout

Hello all, Im looking for reccommendations for a case/sleeve that can be used to wrap around to the back of the device so that when I bend the surface keyboard to the back, there is something between the keyboard and my desk.

hi, when I tick an text ox or when I manually open the onscreen display by touching the icon in the lower right corner, the keyboard opens. most time it is the hand qrite detection thing. so i have to manually select the normal keyboard. is there an option to define which one opens by default...
