Type in Latin, Wulfilan, IPA and Runic.
This one was made primarily for Nordic keyboards, so to an American or German user, for example, the location of some characters will feel unintuitive.
The modifiers are as follows:
None: Type in lower-case Latin script, except ö is ƕ and § is þ.
Shift: Half-Wulfilan compatibility-mode. Where a similar character exists in another script, it is used, or else the Wulfilan character is used.
Caps-lock: 100% Wulfilan
Caps-lock + shift: Latin upper-case
Alt: IPA phonetic script, focusing on sounds that are common in Gothic
Alt + shift: More IPA phonetic
Alt + caps-lock: Runic
Unlike Nordic layouts, combining diacritics are added after a letter by pushing the relevant key, and dead-keys are not used. For example: to write é, you push e first, and then ́.
Space is not always space, but with some modifiers ‘non-breaking space’ and in the runic plane it is a dot as runic script often separate words by dots.
If you are a complete beginner with computers you are advised not to try.
