Carpalx optimizes keyboard layouts to create ones that require less effort and significantly reduced carpal strain!
Have ideas? Tell me.
the best layout
Partially optimized QWKRFY and fully optimized QGMLWY layouts are the last word in easier typing.
the worst layout
A fully anti-optimized TNWMLC layout is a joke and a nightmare to type. It's also the only keyboard layout that has its own fashion line.

download carpalx
Carpalx is a sandbox layout creator—it's entirely command-line driven (there is no interface). The distribution includes the training corpus files, word lists, scripts and configuration files. First, check the requirements to make sure you can run the code. If you just want to use the layouts, download carpalx-msklc them from the next section.

installing layouts on Windows 10
Thanks to Paul Guerin for suggesting fixes to the layouts, providing these instructions and creating the Microsoft Keyboard Layout Creator executables. Refer to his blog Install an additional keyboard layout on Microsoft Windows 10 for details, summarized below.
1. Download and unzip the latest version of carpalx-msklc.
2. Run the setup.exe setup executable from a layout directory (e.g. qgmlwy/setup.exe).
3. Now setup the ability to choose and switch between QWERTY and your new layout. Go to Control Panel > All Control Panel Items > Language > Advanced settings. In the Switching Input Methods category, enable Use the desktop language bar when available.
4. Logout then login. There is no need to reboot.
5. On startup you'll see the Input Method icon in the task bar. This can be set to instead show the Input Method icon in the top-right corner of the desktop where you'll be able to easily switch to either layout with the mouse. Now you can switch at any time to the layout that you want.
creating your own installation executables on Windows 10
1. Download and install the Microsoft Keyboard Layout Creator v14. This tool will work with Windows 10. If the Microsoft link doesn't work, you can download my local copy.
2. From the Microsoft Keyboard Layout Creator select File > Load Source File (e.g. qgmlwy\qgmlwy.klc).
3. Choose Project > Build DLL And Setup Package. The setup executable and DLL will now be created.
carpalx X11 keyboard layouts
The X11 project already features QGMLWB and QGMLWY.
If you'd like to install other layouts, refer to Paul Guerin's blog Install an additional keyboard layout on X11 for instructions.
Many thanks to Sven Hallberg for originally providing X11 configuration files for Carpalx layouts to be used with setxkbmap. He describes installation in his blog.
Richard Gomes contributed an archive that bundles Sven's files, along with examples for KDE/Gnome.

Patches to include Carpalx layouts in xkeyboard-config and kbd have been submitted by Perry Thompson.
