Skarp layouts
Skarp is set of Scandinavian carpalx optimized keyboard layouts influenced by JNSF and Kvikk.
During optimization FJ keys were handled as designated home keys,
making it easier to convert standard keyboards to Skarp ones as long as keycap profile is uniform.
Carpalx report with essential keyboard stats is available for all layouts.
Typing effort takes into account 29 letters and three most common punctuation characters (full stop, comma and hyphen).
Statistics including frequency distribution is based on
Norwegian,
Danish and
Swedish wikipedia articles.
Ten finger distribution takes into account last letter frequencies and assumes that opposite hand's thumb is
responsible for space bar. While eight finger distribution is calculated without taking into account spaces.
Word reports are available.
Norwegian layout
Carpalx typing effort is 1.868, much lower then QWERTY and Dvorak,
but higher then Kvikk.

XKB and KMonad configurations
Skarp XKB and KMonad configurations combine Skarp optimizations with symbols imported from standard Norwegian, Danish and Swedish layouts.
Linux users can copy XKB configuration file to /usr/share/X11/xkb/symbols/ directory:
sudo cp skarp /usr/share/X11/xkb/symbols/skarp
Norwegian layout can be selected with
setxkbmap skarp
and set as default as
localectl --no-convert set-x11-keymap skarp pc105
Danish layout can be selected with
setxkbmap skarp -variant da
and set as default as
localectl --no-convert set-x11-keymap skarp pc105 da
Swedish layout can be selected with
setxkbmap skarp -variant sv
and set as default as
localectl --no-convert set-x11-keymap skarp pc105 sv
In all layouts scroll lock can be used to switch between äö⇄æø groups.
One can use KMonad configuration instead of XKB.
Linux users need to set uinput permissions
and specify path to input device
before loading KMonad configurations.
Norwegian layout for can be selected with
kmonad skarp-nb.kbd
Danish layout for can be selected with
kmonad skarp-da.kbd
Swedish layout for can be selected with
kmonad skarp-sv.kbd
Another alternative is to use Skarp configurations
for keyd key remapping daemon.
