First, you must decide which keyboard layout you'd like to use, and more, which keyboard layout is best for you in the future. Today, there're many keyboards especially for you, such as one hand qwerty, half qwerty half keyboard, dvorak, etc. How to decide which one you prefer to largely depends on the following reasons. 1, which one will allow you to type fastest? 2, how long will it take you to learn? 3, which one is the best for you to work in the workplace? That means you have no chance to select an especial keyboard layout during working. In theory, those using one handed dvorak should be best. But it's just not the case. Using one handed dvorak, you have to get one dvorak keyboard, and it makes you greatly different from other two handed person, and more, it's more expensive than others. By comparing with these, it's a good choice to choose a normal standard keyboard. Why? It's less expensive, of course. And being compatible with the mainstream for work and play, enables you to use the same computer and keyboard as any two handed person at any place. Therefore, you could not be disadvantaged by using the standard keyboard.
Second, you should choose a good one hand typing program to help you take practice. Typing is not a pleasure process to you, as well as to two handed person. It's maybe very monotonous and bothersome. Absolutely, the one hand typing program must be helpful and interesting as well, and the most important is that it'll offer the step by step instruction to help you complete the typing course. You could refer to the typing program gs typing tutor, which provides the one hand typing course. After entering into its main screen, choose the option button at the bottom, then point at the general menu, the keyboard layouts are listed here. The program offers four one hand keyboard layouts: english us left hand, english us right hand, dvorak left hand, and dvorak right hand. English us left (right) hand keyboard layout is actually the normal keyboard layout, that's qwerty. Choose any one you prefer to, and take more practice following the one hand typing courses.
After choosing the keyboard layout and one hand typing program, you can begin to type. As the beginner, you must get your typing habit right at the first time, don't look at your hand, don't hunt and peck, and learn to touch type. There is no other way to learn how to type, than to practice typing, over and over and over again. No doubt, it will take your a lot of time to practise, of course, and you'll be frustrated by the long process, but as long as you take time to practise, you can greatly improve typing speed.
Aimed at the basic computer skill, you can go out to find the normal job as the two handed person. And the most important thing is that you don't feel self-contempt for how you're not different from others who can use the computer to perform a variety of tasks by two hands.
