JASF layout

JASF is Scandinavian carpalx optimized keyboard layout influenced by Skarp and Kvikk.

Layout is optimized for 1:1:1 mixed content based on articles from Norwegian, Danish and Swedish wikipedia.

During optimization FJ keys were handled as designated home keys.

Carpalx typing effort is in 1.881-2.084 range, much lower then QWERTY and Dvorak, but higher then Kvikk.

Typing effort takes into account 29 letters and three most common punctuation characters (full stop, comma and hyphen).

It's easy to convert standard Norwegian, Danish, Swedish and Nordic keyboards to JASF ones as long as keycap profile is uniform.
