Typewriter keyboard

The 1874 Sholes & Glidden typewriters established the QWERTY layout for the letter keys that is used nowadays in Anglophone countries for virtually all computer keyboards and the majority of other keyboards. Other nations using the Latin alphabet may use variants of the QWERTY layout, for example the French AZERTY layout.

Radically different layouts such as the Dvorak keyboard have been proposed but have not been able to displace the QWERTY layout, despite the advantages claimed by their proponents.
