Lesson 20 introduces the Z , the /, and the ? Key (use SHIFT and the / key at the same time!)
With your fingers on the home row keys, use your left Pinky finger to strike the Z key. Next, use your right Pinky finger to strike the / key. To strike the ? key, you will use your Right Pinky Finger and your left Pinky Finger to strike and hold the Left Shift key.
The ? is on the top row of a key. All symbols on the top row of a key need to be used at the same time as you strike and hold down the shift key with your opposite pinky finger.
