JCUKEN

JCUKEN (ЙЦУКЕН, also known as YCUKEN, YTsUKEN and JTSUKEN) is the main Cyrillic keyboard layout for the Russian language in computers and typewriters. Earlier in Russia JIUKEN (ЙІУКЕН) layout was the main layout, but it was replaced by JCUKEN when the Russian alphabet reform of 1917 removed the letters Ѣ, І, Ѵ, and Ѳ. The letter Ъ had decreased in usage significantly after the reform.

JCUKEN is the basis for many other Cyrillic layouts. For the current moment Microsoft Windows supports the following layouts: Azerbaijani (Cyrillic), Bashkir, Belarusian, Kazakh, Kyrgyz, Mongolian, Tajik, Ukrainian, Uzbek (Cyrillic), Yakut (Sakha). The Belarusian, Ukrainian and Mongolian layouts have been available since Windows 95; Azeri, Kazakh, Kyrgyz, Tatar, Uzbek since Windows XP; Bashkir and Tajik since Windows Vista; Yakut since Windows 7.

Other operating systems such as Linux may have their own additional custom layouts for the same or other languages.
