QWERTY called "US-International layout" is, in fact, OS-dependent. There exist other layouts that try to overcome this shortcoming. One popular is EurKEY which is available for Windows, OS X and Linux. A dead key is not used, like a grave accent (`) on a QWERTY keyboard, although some people use a dead key. Depending on the operating system and sometimes the application program being used, there are many ways to generate Latin characters with accents independently of the layout in use. Minor changes to the arrangement are made for other languages. There are a large number of different keyboard layouts used
QWERTY Edison's 1872 electric print-wheel device which later became the basis for Teletype machines; Lucien Stephen Crandall's typewriter (the second to come onto the American market) whose type was arranged on a cylindrical sleeve; the Hammond typewriter of 1887 which used a semi-circular "type-shuttle" of hardened rubber (later light metal); and the Blickensderfer typewriter of 1893 which used a type wheel. The early Blickensderfer's "Ideal" keyboard was also non-QWERTY, instead having the sequence "DHIATENSOR" in the home row, these 10 letters being capable of composing 70% of the words in the English language. Alternating hands while typing is a desirable trait
