Lesson 12 introduces the Y , the T, and the Tab Key.
With your fingers on the home row keys, use your left Pointer (Index) finger to strike the T key. Next, use your right Pointer (Index) finger to strike the Y key. To strike the Tab key, you will use your Left Pinky Finger. Remember to hold onto the F key with your Left Pointer finger to be able to find Home Row again with you left hand quickly!
The Tab key is used to jump the cursor to the next tab setting (also to indent the start of a paragraph).
