English, a language with accents ('diacritics') appearing only in a few words of foreign origin. The standard US keyboard has no provision for these at all; the need was later met by the so-called "US-International" keyboard mapping, which uses "dead keys" to type accents without having to add more physical keys. (The same principle is used in the standard US keyboard layout for MacOS, but in a different way.) Most European (including UK) keyboards for PCs have an AltGr key ('Alternative Graphics' key, replaces the right Alt key) that enables easy access to the most common diacritics used in the territory where sold. For example, default keyboard mapping for the UK/Ireland keyboard has the diacritics used in Irish but these are rarely printed on the keys; but to type the accents used in Welsh and Scots Gaelic requires the use of a "UK Extended" keyboard mapping and the dead key or compose key method. This arrangement applies to Windows, ChromeOS and Linux; MacOS computers have different techniques. The US International and UK Extended mappings provide many of the diacritics needed for students of other European languages. Other keys and characters Specific language variants Minor changes to the arrangement are made for other languages. There are a large number of different keyboard layouts used for different languages written in Latin script. They can be divided into three main families according to where the , , , , and keys are placed on the keyboard. These are usually named after the first six letters, for example this QWERTY layout and the AZERTY layout. In this section you will also find keyboard layouts that include some additional symbols of other languages. But they are different from layouts that were designed with the goal to be usable for multiple languages (see Multilingual variants). The following sections give general descriptions of QWERTY keyboard variants along with details specific to certain operating systems. The emphasis is on Microsoft Windows. English Canada English-speaking Canadians have traditionally used the same keyboard layout as in the United States, unless they are in a position where they have to write French on a regular basis. French-speaking Canadians respectively have favoured the Canadian French keyboard layout (see French (Canada), below). The CSA keyboard is the official multilingual keyboard layout of Canada. United Kingdom The United Kingdom and Ireland use a keyboard layout based on the 48-key version defined in the (now
