If you are totally stuck, try clearing Shield Bluetooth force stop, cache, data, reboot. I did not need to do this.
In the meantime you will need on of these . . .
Remote Android App Works with phone or tablet. It has a keyboard that comes in handy for setting up the Shield bit keyboard its keyboard can be hit or miss. Physical wireless keyboards can work well or drive you crazy depending on conditions. Logitech K400 is a good one but large and unnecessary for everyday use. The little Rii keyboards can be good or bad depending on the model.
I have learned how to do everything possible without a keyboard.
Remember . . . USB wired keyboards and mice always work
