To learn to type you can open Google translate, set it for Arabic to English, and you'll see, at the bottom of the little window, the symbol of an ع . If you click on it you will see the symbol of a keyboard. Open it, and type on your keyboard (Not on the virtual keyboard, but on YOUR actual keyboard), while looking at the screen at the virtual keyboard and typing into the Google translate window. Like this you'll learn to type without looking. I can now type in Arabic without looking. It's great.
Google translate also gives you an instant translation and therefore it helps you notice any errors more easily.
