The Icelandic keyboard layout is a national functional keyboard layout described in ÍST 125,[1] used to write the Icelandic language on computers and typewriters. It is QWERTY-based and features some influences from the continental Nordic layouts. It supports the language's many special letters, some of which it shares with the other Nordic languages:
The letters Å/å, Ä/ä, Ÿ/ÿ, Ü/ü, Ï/ï, and Ë/ë can be produced with the Icelandic keyboard by first pressing the or (for ¨) dead key located below the key, and then the corresponding letter (i.e. followed by yields å). These letters are not used natively in Icelandic, but may have been implemented for ease of communication in other Nordic languages.
