@johnaalex: I've had a look into this for you, and sadly we don't currently have any wireless Bluetooth keyboards available to purchase on our website, however you should be good to go with whichever option you go for via a reputable third party retailer. To connect your Bluetooth keyboard to the TV, enable pairing by following the manufacturers instructions, then follow the steps below.
Settings > General > External Device Manager > Input Device Manager > Bluetooth Device List > Select the keyboard from the available connection options. I hope this helps.
