Language code

Country codes are short alphabetic or numeric geographical codes (geocodes) developed to represent countries and dependent areas, for use in data processing and communications. Several different systems have been developed to do this. The most famous of these is ISO 3166-1. Country code - Lists of country codes by country.

Main article: ISO 3166-1 This standard defines for most of the countries and dependent areas in the world: a two letter (ISO 3166-1 alpha-2) a three-letter (ISO 3166-1 alpha-3), and a three-digit numeric (ISO 3166-1 numeric) code. The two-letter codes are used as the basis for some other codes or applications, e.g. for ISO 4217 currency codes and with deviations for country code top-level domain names (ccTLDs) on the Internet: list of Internet TLDs.

Although there are a large number of different keyboard layouts used with different languages written in Roman script, most of these layouts are quite similar. According to where the keys for Q, A, Z, M, and Y are placed on the keyboard, they can be divided into three main families. These are usually named according to the first six letters. Note that while the core of the keyboard, the alphabetic section, remains fairly constant, and the numbers from 1-9 are almost invariably on the top row, keyboards differ vastly in: t ...

The keys labelled only with a capital letter can type both small and capital letters. To type the symbol at the top left of a key, the Shift key, often labelled "↑", is used. To type the symbol at the bottom right of a key, the AltGr key is used. (Further symbols are available on the keyboards of laptop computers, which require further keystroke combinations.) In the standard keyboard structure are included too the control, alternative, and function keys. Together, these keys are commonly known as modifier keys.

Chinese, Japanese and Korean require special input methods (often abbreviated to CJK IMEs) due to the thousands of possible characters in these languages. Various methods have been invented to pack all these possibilities into a normal QWERTY keyboard, so East Asian keyboards are essentially the same as those in other countries. However, their input methods are considerably more complex, without one-to-one mappings between keys and characters. In general, you need to first narrow down the range of possibilities (most often by entering ...

Some keyboard layouts for non-Roman alphabetic scripts, most notably the Greek layout, are actually based off the QWERTY layout, in that, as far as possible, glyphs are assigned to keys which bear similar-sounding or -appearing glyphs in QWERTY. This saves learning time for those already familiar with QWERTY. This is not a general rule, though, and many non-Roman keyboard layouts are invented from scratch. Also, most non-Roman keyboard layouts have the capacity to be used to input Roman letters as well as the script of the lang ...
