/*
 * About this keymap:
 * 
 * The Dvorak layout shown herestems from my early Kinesis years, using the Contour PS/2 with a Dvorak
 * software layout. Because of this, the RBRC and LBRC were on opposite sides of the board in the corner
 * keys. I've decided to continue using this layout with my ErgoDox.
 *
 * The QWERTY layout shown here is based entirely on the Kinesis Advantage layout, with the additional
 * keys as shown in the diagrams. The Colemak layout is merely an adaptation of that.
 *
 * I've enabled persistent keymaps for Qwerty, Dvorak and Colemak layers, similar to the default Planck
 * layouts.
