Dvorak is an alternative to Qwerty. It is a keyboard layout designed to minimize movement, and make typing easy and painless. The idea behind it is to have the most commonly typed keys under the fingers, and make it easy to type common words and combinations of letters. To give you a perspective, consider that if average Dvorak typist's fingers travel one mile in a day of typing, Qwerty typist's will travel anything 16 to 20 miles a day. By the way, don't ask me the proof for above example.
