And now, for the other hand!
As before, remember to keep the hand that is not typing resting on the home row. Do not try to cheat by keeping both hands resting on the numbers row, since that will cause you to lose your bearings for the rest of the keyboard. Instead, keep your fingers in contact with the home row when not in use, just as you always do. Having to use the comma and period frequently in this lesson will keep you honest!
You might want to run through the exercise Do You Have My Number? again before beginning this lesson's exercise. This will help affirm your muscular memory for where the number key are in relation to the home row.
Keep those Principles for Effective Learning fresh in your mind!
