corresponding letter. The Nordic letters Å/å and Ä/ä can be produced by first pressing , located below the key, and (for ¨) which also works for the non-Nordic ÿ, Ü/ü, Ï/ï, and Ë/ë. These letters are not used natively in Icelandic, but may have been implemented for ease of communication in other Nordic languages. Additional diacritics may be found behind the key: for ˋ (grave accent) and for ˆ (circumflex). Irish Microsoft Windows includes an Irish layout which supports acute accents with for the Irish language and grave accents with the dead key for Scots Gaelic. The other Insular Celtic languages have their own layout. The UK or UK-Extended layout is also frequently used. Italian Braces (right above square brackets and shown in purple) are given with both AltGr and Shift pressed. The tilde (~) and backquote (`) characters are not present on the Italian keyboard layout (with Linux, they are available by pressing ++, and ++; Windows might not recognise these keybindings). When using Microsoft Windows, the standard Italian keyboard layout does not allow one to write 100% correct Italian language, since it lacks capital accented vowels, and in particular the È key. The common workaround is writing E' (E followed by an apostrophe) instead, or relying on the auto-correction feature of several word processors when available. It is possible to obtain the È symbol in MS Windows by typing + . Mac users, however, can write the correct accented character by pressing + + or, in the usual Mac way, by pressing the correct key for the accent (in this case + ) and subsequently pressing the wanted letter (in this case + ). Linux users can also write it by pressing the key with enabled. There is an alternate layout, which differs only in disposition of characters accessible through , and includes the tilde and the curly brackets. It is commonly used in IBM keyboards. Italian typewriters often have the QZERTY layout instead. The Italian-speaking part of Switzerland uses the QWERTZ keyboard. Latvian Although rarely used, a keyboard layout specifically designed for the Latvian language called ŪGJRMV exists. The Latvian QWERTY keyboard layout is most commonly used; its layout is the same as Latin ones, but with a dead key, which allows entering special characters (āčēģīķļņõŗšūž). The most common dead key is the apostrophe ('), which is followed by Alt+Gr (Windows default for Latvian layout). Some prefer
