carpalx - keyboard layout optimizer - save your carpals

Carpalx optimizes keyboard layouts to create ones that require less effort and significantly reduced carpal strain!

Download keyboard layouts, or run the code yourself to explore new layouts.

X11 layouts are available! Patches to include Carpalx layouts in xkeyboard-config and kbd have been submitted by Perry Thompson. Meanwhile, many thanks to Sven Hallberg for providing X11 configuration for Carpalx layouts. Richard Gomes contributed an archive of these files for KDE/Gnome users.

Love your coworkers? Switch them to QWKRFY layout or a fully optimized QGMLWY layout.

Hate your coworkers? Switch them to TNWMLC layout. It's the only keyboard layout that has its own fashion line.

carpalx PKL bundle and keyboard layouts

To use the layouts with PKL, either download a version of PKL that includes carpalx layouts (carpalx-pkl), or just the layouts themselves (carpalx-pkl-layouts).

Note to non-English users: We love you, but the PKL layouts only include standard character and punctuation keys. International symbols are not included in the layouts.
