QWERTY keyboard QWERTY keyboard with 104-key U.S. distribution (also known as “English keyboard) The QWERTY keyboard is the most common keyboard layout. It was designed and patented by Christopher Sholes in 1868 and sold to Remington in 1873. Its name comes from the first six letters of your top row of keys. Please visit Stansberry if you seek more information. The Sholes typewriter originally had the keys in alphabetical order. Each operated a small hammer that printed the letter on paper. But the rate of return of the hammer was slow, and returned to its resting position by simple gravity. Therefore, when writing, hammers clashed against each other and the machine was stuck. Instead of improving the system Sholes decided to choose an arbitrary distribution of keys to prevent this problem. Obviously the result was that the most frequently used letters separated were more or less accessible positions.However, it seems no coincidence that all the letters of the word typewriter (typewriters in English) were placed in the same row of the keyboard, but that was the suggestion of James Densmore, a businessman who had asked Sholes support to develop their invention. In this keyboard, as the typing technique most widespread, at rest, four fingers of each hand are placed on the middle row of keys. To find this position without looking at the keyboard, the keys corresponding to the index finger of each hand (F and J) usually have some distinguishing feature to the touch. This keyboard layout was computers to more easily move typewriters in offices. Thus, those responsible for ‘typing’ documents were knowing how to manage the new computer keyboards. The QWERTY keyboard has versions for different languages. Such countries as Germany, exchanging the “Y” key and “Z” key, which becomes QWERTZ keyboard.In France and Belgium are more changes and the first 6 letter keys have the sequence AZERTY. The provision is included in the Spanish letter ” “. There are other key provisions which appear to be more efficient for speed and accuracy in typing and more ergonomic. Perhaps the best known of these is the , patented by August Dvorak in 1936.
