This QMK model represents the printable keyboard shape identified as concertina_64key in the DMOTE application’s list of GNU make targets, available here, 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.

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

Firmware

Brand new to QMK? Start here.

The default keymap for this layout has a QWERTY base layer (0) but is intended for running Colemak on the OS side. It has a separate key layer (1) that forces Colemak from the QMK side in case the keyboard has to be used with a computer that does not run Colemak. Layer 2 flips the navigation clusters around. Layer 3 is numbers and mouse control.

Building from the CLI
