an industrial French layouts, and also the French quotation marks or guillemets, «»). Furthermore, its dead-letter option for all the diacritical keys allows for easy input of all the possibilities in French and many other languages (áàäãâéèëêíìïîñóòöõôúùüû). 'ç' is, however, a separate key (but only as a lowercase letter in the basic French standard layout). The US-International keyboard may also used for the same reason (notably by programmers as it allows easier input of ASCII characters, provided that they are trained to a QWERTY layout rather than the most common AZERTY layouts available in most computer shops, including online). An alternative (extremely rarely found) to AZERTY is the Bépo layout : it's not available on any notebook, but may be used by adding an external keyboard, bought separately from some specialized shops. . Apple Apple's keyboards use the same AZERTY layout in both France and Belgium. Based on the Belgian version, the most notable differences are the locations for the @-sign and €-sign, among others. MacOS also supports the standard French layout for non-Apple keyboards; the standard Belgian layout, however, is available through third-party support only. Arabic There is an Arabic variant of the AZERTY keyboard. It is especially used in the African countries Algeria, Chad, Comoros, Djibouti, Mauritania, Morocco, Tunisia and in Arab communities in French-speaking countries to be able to type both in Arabic and in French. Tamazight (Berber) The Tamazight (Latin) standards-compliant layout is optimised for a wide range of Tamazight (Berber) language variants – including Tuareg variants – rather than French, though French can still be typed quickly. It installs as "Tamazight_L" and can be used both on the French locale and with Tamazight locales. QWERTY and QWERTZ adaptations of the layout are available for the physical keyboards used by major Amazigh (Berber) communities around the world. Other layouts exist for closer backwards compatibility with the French layout. They are non-standards-compliant but convenient, allowing typing in Tifinagh script without switching layout: Tamazight (International) extends the French layout with Tamazight (Berber), and offers secondary Tifinagh script access by deadkey. It installs as "Tamazight (Agraghlan)" or "Français+" and is available from the official site of the Algerian High Council for Amazighity (HCA). Tamazight (International)+ is optimised for Tamazight (Berber), but retains close French compatibility and provides easy typing in Tifinagh script by Caps Lock. It installs as "Tamazight (Agraghlan)+" or "Tamazight_LF". All the above layouts were designed by
