I neglected to mention that when you turn the keyboard over to get at the bottom, you should be cautious to have the end that has the joystick off the edge of the table or support you are using. Otherwise the keyboard will be resting on the joystick itself and could probably cause damage. When the keyboard is upside down it will be resting on the keybed in the front, so it's a good idea to have some sort of padding (I used a blanket).
