Colemak is a keyboard layout for Latin-script alphabets. The layout is designed to make typing more efficient and comfortable by placing the most frequently used letters of the English language on the home row. Created in 2006, it is named after its inventor, Shai Coleman. Most major modern operating systems such as Mac OS, Linux, Android, Chrome OS, and BSD support Colemak natively. A program to install the layout is available for Microsoft Windows. On Android and iOS, the layout is offered by several virtual keyboard apps like GBoard and SwiftKey, as well as by many apps which support physical keyboards directly.
