I paired my Apple Bluetooth keyboard with the Touchpad and it works great. I wish the volume keys and all that stuff would work too, but I guess just being able to type fast is good enough. So here were the steps I took to pair it
1. While keyboard is off, hold power button until it goes into pairing mode (the light starts blinking a bit).
2. On Touchpad, search for wireless keyboards and select "Apple Wireless Keyboard".
3. On Touchpad type in any password you want (I used a 4 number pin).
4. Right after you click OK on the Touchpad, type the same password in on the keyboard and click the enter key after. After this, the keyboard should be paired
