Take a pencil and paper. Write your name with your thumb on the top/eraser end of the pencil. Then write your name with thumb and fingers holding the pencil normally. Fine motor control is in your fingers, not your thumb. There is a reason it' called an "opposable" thumb and is unique to the humans/primates. I'm sure that with sufficient practice you could eventually learn to write your name the first way (people have learned to paint with their toes after all). But I think you;d learn the "fingers and thumb" way faster. Same thing with the sticks on your transmitter.
