NORN KJOKL

There's a "virtual keyboard" website called gate2home ...

... which simulates keyboards for a large variety of languages.

It looks like the Faroese keyboard has all the characters needed for Nynorn.

Thanks for the link! Faroese keyboard does have all the letters needed for Shetland Nynorn, but it misses letter 'þ' which is used in Orkney Nynorn:

... and is only present in Icelandic keyboard layout AFAIK. This is why I've been thinking about creating the Nynorn keyboard layout, it will soon be done for Windows and Linux, and probably Mac if there's people interested (and there might well be!).
