withdrawn) British Standard BS 4822. It is very similar to that of the United States, but has an AltGr key and a larger Enter key, includes £ and € signs and some rarely used EBCDIC symbols (¬, ¦), and uses different positions for the characters @, ", #, ~, \, and |. The BS 4822:1994 standard did not make any use of the AltGr key and lacked support for any non-ASCII characters other than ¬ and £. It also assigned a key for the non-ASCII character broken bar (¦), but lacked one for the far more commonly used ASCII character vertical bar (|). It also lacked support for various diacritics used in the Welsh alphabet, and the Scots Gaelic alphabet; and also is missing the letter yogh, ȝ, used very rarely in the Scots language. Therefore, various manufacturers have modified or extended the BS 4822 standard: The B00 key (left of Z), shifted, results in vertical bar (|) on some systems (e.g. Windows UK/Ireland keyboard layout and Linux/X11 UK/Ireland keyboard layout), rather than the broken bar (¦) assigned by BS 4822 and provided in some systems (e.g. IBM OS/2 UK166 keyboard layout) The E00 key (left of 1) with AltGr provides either vertical bar (|) (OS/2's UK166 keyboard layout, Linux/X11 UK keyboard layout) or broken bar (¦) (Microsoft Windows UK/Ireland keyboard layout) Support for the diacritics needed for Scots Gaelic and Welsh was added to Windows and ChromeOS using a "UK-extended" setting (see below); Linux and X11 systems have an explicit or reassigned compose key for this purpose. UK Apple keyboard The British version of the Apple Keyboard does not use the standard UK layout. Instead, some older versions have the US layout (see below) with a few differences: the sign is reached by and the sign by , the opposite to the US layout. The is also present and is typed with . Umlauts are reached by typing and then the vowel, and ß is reached by typing . Newer Apple "British" keyboards use a layout that is relatively unlike either the US or traditional UK keyboard. It uses an elongated return key, a shortened left with and in the newly created position, and in the upper left of the keyboard are and instead of the traditional EBCDIC codes.
