I was actually trying to figure out if you can fold the keyboard all the way back while attached too. It seems like you can't and just have to detach it.
After using it a bit, the keyboard connection seems very sensitive. If I open the keyboard from cover mode and start to try and type, it doesn't do anything. I have to dicconect and reconnect the keyboard and then it works fine. This is my first Smart Keyboard for the iPad Pro, so I'm not sure if that's just an issue with how the keyboards are? Or if it's just this model keyboard. I've only had it for a day and it's already getting annoying.
Do you think you could use an Apple Smart Cover with the rear protective casing ?
