<P> Today, most keyboards use one of three different mechanical layouts, usually referred to as simply ISO (ISO / IEC 9995 - 2), ANSI (ANSI - INCITS 154 - 1988), and JIS (JIS X 6002 - 1980), referring roughly to the organizations issuing the relevant worldwide, United States, and Japanese standards, respectively . (In fact, the mechanical layouts referred such as "ISO" and "ANSI" comply to the primary recommendations in the named standards, while each of these standards in fact also allows the other way .) Keyboard layout in this sense may refer either to this broad categorization or to finer distinctions within these categories . For example, as of May 2008 Apple Inc produces ISO, ANSI, and JIS desktop keyboards, each in both extended and compact forms . The extended keyboards have 110, 109, and 112 keys (ISO, ANSI, and JIS, respectively), and the compact models have 79, 78, and 80 . </P> <P> 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 . </P> <P> Some users choose to attach custom labels on top of their keycaps . This can be e.g. for masking foreign layouts, adding additional information such as shortcuts, learning aid, gaming controls, or solely for decorational purposes . </P> <P> The functional layout of the keyboard refers to the mapping between the physical keys, such as the A key, and software events, such as the letter "A" appearing on the screen . Usually the functional layout is set to match the visual layout of the keyboard being used, so that pressing a key will produce the expected result, corresponding to the legends on the keyboard . However, most operating systems have software that allow the user to easily switch between functional layouts, such as the language bar in Microsoft Windows . For example, a user with a Swedish keyboard who wishes to type more easily in German may switch to a functional layout intended for German--without regard to key markings--just as a Dvorak touch typist may choose a Dvorak layout regardless of the visual layout of the keyboard used . </P>
