/*
 * About this keymap:
 * 
 * The Dvorak layout shown here stems 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. When I originally set up this keymap, I'd decided to continue using this layout with my ErgoDox.
 * I've since modified my layout to be more effective for me and to more closely match my other ortho
 * keyboard layouts
 *
 * 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.
 *
 * What's New:
 * 
 * I've overhauled this Dvorak layout a bit to more match what I've got on my other Ortho boards. For
 * some keys, I'm moving away from my old Kinesis keymap and adding the brackets and braces to the
 * inner column vertical keys. I figure this will help me have better ease of use. In this update, I
 * have also removed the keypad layer since I no longer use that at all, and have remapped the MEDIA
 * layer a bit.
