Select a free online typing program that appeals to you. Many offer a handful of lessons and a few typing games to start you out.
Place your fingers on the keyboard, over the proper letters. Most keyboards have small ridges on the letters "F" and "J". These ridges indicate the home position for your index fingers while each following finger rests on the following key. After typing a letter, always return your fingers to the home position. The letters "G" and "H" do not have fingers covering them in the home row.
Follow your selected typing program's instructions to begin to learn the basics of typing. At first, look at the keyboard and concentrate on how it feels to move each finger to the proper letter. Once you have started to memorize the positions of the keys, stop looking at the keyboard and allow just your fingers, and not your eyes, to move over the keys.
Start to type emails with your fingers in the proper locations instead of hunting and pecking. This will take longer at first, but the more you practice the quicker you will become. Practice typing the words on cereal boxes, junk mail, paragraphs out of books or anything else you get your hands on.
