Hunt-and-peck

Tom is a hunt-and-peck typist.

When individuals type information into an automatic teller machine or enter a password to open a lock, they simply push a sequence of keys. They first find the key on the keypad and then push it with the index finger on their dominant hand until all the keys are pressed. Children and adults tend to use this hunt-and-peck method when they encounter an unfamiliar keypad.
