Many office professionals today have an interest in replacing the keyboard most people currently use, known as the QWERTY keyboard, with a keyboard that can keep up with technological changes and make offices more efficient. The best choice is the Dvorak keyboard. Studies have shown that people using the Dvorak keyboard can type 20-30% faster and cut their error rate in half. Dvorak puts vowels and other frequently used letters right under the fingers (on the home row), where typists make 70% of their keystrokes. The paragraph best supports the statement that the Dvorak keyboard...
