The 64key layout

This folder represents the keyboard configuration identified as concertina_64key in the DMOTE applications list of GNU make targets, as of version 0.7.0 of that application. The QMK code is fully compatible back to version 0.6.0, which introduced the Concertina.

The default keymap for this layout has a QWERTY base layer but is intended for running Colemak on the OS side. It has a separate key layer that forces Colemak from the QMK side in case the keyboard has to be used with a computer that does not run Colemak.

A full set of printable caps to match the keymap is available in the dmote-keycap application, here.
