swapped. South Slavic Latin The Serbo-Croatian Latin and Slovene keyboard layout has five additional special characters Č, Ć, Ž, Š and Đ. This keyboard layout was standardized in the 1980s in Yugoslavia. Characters Ć and Đ are only part of Gaj's Latin alphabet but not part of the Slovene alphabet, nevertheless they remain in Slovenian keyboards (for economic reasons, for historical reasons and for writing words in the closely related South Slavic languages). The Ž is on the right side of the Ć key on keyboards which have a longer backspace key, and the usual inverted L shaped Enter key. The layout makes heavy use of the AltGr (right Alt) key for non-alphabetic characters and dead key combinations for adding diacritics to Latin characters. It is possible to type German and Italian using only the Serbo-Croatian keyboard layout. There is a proposed variant of new Slovene keyboard layout, which would remove Ć and Đ from top layout and add @ instead. The command keys would also become translated into Slovene and some minor second level layout changes would be made. For Serbian, there is also a Cyrillic keyboard variant, in which and are replaced with Љ (Lj) and Њ (Nj) respectively. However, the Apple keyboards for Croatian are QWERTY. Swiss (German, French, Italian, Romansh), Liechtenstein, Luxembourg The layout of the Swiss keyboard is established by the national standard SN 074021:1999. It is designed to allow easy access to frequently used accents of the French, German and Italian languages and major currency signs. It was designed from the beginning for usage with multiple languages, also beyond Swiss languages, in mind. The difference between the Swiss German () and the Swiss French () layout is that the German variety has the German umlauts (ä, ö, ü) accessible in the unshifted state, while the French version has some French accented characters (é, à, è) accessible in the unshifted state. The actual keyboards have the keys engraved for both variations; the difference is only in the driver (software) settings. In the latest versions of Windows there are also separately listed driver settings for Swiss Italian and Swiss Romansh, but they correspond to the Swiss French and Swiss German layout, respectively. In Mac OS X 10.6 and Linux, only Swiss French and Swiss German are available, and on iPadOS, the only layout is Swiss German. (The Swiss German layout is not available for anything else.)
