Keyboard layout
Mechanical, visual, and functional layouts
A Visual layout refers to the symbols printed on the physical keycaps. Visual layouts vary by language, country, and user preference, and any one mechanical and functional layout can be employed with a number of different visual layouts. For example, the "ISO" keyboard layout is used throughout Europe, but typical French, German, and UK variants of mechanically identical keyboards appear different because they bear different legends on their keys. Even blank keyboards – with no legends – are sometimes used to learn typing skills or by user preference.
