can I use special mouse and keyboard on algs?

From my knowledge under Rule 5.1 of the Year 5 ALGS Rules  They aren't allowed because they are classified as a keypad, where it states in Rule 5.1 , "Competitors may use a keyboard and a mouse or a PlayStation or Xbox controller while
competing (“Input Device”)." It only mentions keyboards, im not too sure about the mouse but if it is classified as a keypad i believe it wont be allowed.
