The Dvorak pattern is intended for the English language. Dvorak believed that there were many problems with the original QWERTY keyboard pattern. The Dvorak pattern was designed with the belief that it would significantly increase typing speeds with respect to the QWERTY layout. The Dvorak layout was designed to replace the QWERTY keyboard pattern (the de facto standard keyboard layout). However, there is no evidence to support this assertion, except that the arrangement does, in fact, inhibit fast typing.

According to the popular myth, Sholes arranged the keys in their odd fashion to prevent jamming on mechanical typewriters by separating commonly used letter combinations. The arrangement of characters on a QWERTY keyboard was designed in 1868 by Christopher Sholes, the inventor of the typewriter. It became popular with the success of the Remington No. The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to E. The name comes from the order of the first six keys on the top left letter row of the keyboard (Q W E R T Y). QWERTY Typing Keyboard Layout is a keyboard design for the Latin-script alphabets.

The functional layout is the arrangement of the key-meaning associations, determined in software, of all the keys of a keyboard. Visual layout is the arrangement of the legends (labels, markings, engravings) that appear on the keys of a keyboard. The mechanical layout is the placements and keys of a keyboard. The typing keyboard layouts are any specific mechanical, visual, or functional arrangement of the keys, legends, or key-meaning associations (respectively) of a computer, typewriter, or other typographic keyboards.
