The UK Extended keyboard uses mostly the AltGr key to add diacritics to the letters a, e, i, n, o, u, w and y (the last two being used in Welsh) as appropriate for each character, as well as to their capitals. Pressing the key and then a character that does not take the specific diacritic produces the behaviour of a standard keyboard. The key presses followed by spacebar generate a stand-alone mark.: grave accents (e.g. à, è, etc.) needed for Scots Gaelic are generated by pressing the grave accent (or 'backtick') key , which is a dead key, then the letter. Thus produces à. acute accents (e.g. á) needed for Irish are generated by pressing the key together with the letter. Thus produces á; produces Á. the circumflex diacritic needed for Welsh may be added by , acting as a dead key combination, followed by the letter. Thus then produces â, then produces the letter ŵ.
