I can only seem to find Xbox qwerty keyboards that are attached to the controller. I type very little and would like to grab the keyboard when I need and toss it aside when done with it not have it on my controller at all times. There are a bunch of super cheap small qwerty bluetooth keyboards out there, do any work with Xbox? Bluetooth or any other type of wireless? If something is working for you tell me what you are using so I can look it up. Thanks
