The Norwegian languages use the same letters as Danish, but the Norwegian layout differs from the Danish regarding the placement of Æ, Ø and \ (backslash) keys.
On the Danish keyboard Ø and Æ have switched places, which many Norwegians find annoying when using Danish keyboards.
The Swedish and Norwegian keyboard layouts have Ö/ö and Ø/ø and Ä/ä and Æ/æ at the same place. (Ö/ö and Ø/ø are differing glyphs representing the same letter and so is Ä/ä and Æ/æ. Ö/ö was used in Denmark and Norway as well in the not very distant past, and there are still Norwegians using Ö/ö in handwriting.)
