// The underscores don't mean anything - you can have a layer called STUFF or any other name.
// Layer names don't all need to be of the same length, obviously, and you can also skip them
// entirely and just use numbers.

// This a slightly modified 'default' keymap that's closer to the Mac keyboard layout. I like the position
// of 'esc' and 'tab' better this way. I also got rid of the backlighting control key and the dvorak and
// colemak layers. I added an 'fn' layer that makes the 'bspc' a forward delete (like on OSX).
