 * Force NKRO
 *
 * Force NKRO (nKey Rollover) to be enabled by default, regardless of the saved
 * state in the bootmagic EEPROM settings. (Note that NKRO must be enabled in the
 * makefile for this to work.)
 *
 * If forced on, NKRO can be disabled via magic key (default = LShift+RShift+N)
 * until the next keyboard reset.
 *
 * NKRO may prevent your keystrokes from being detected in the BIOS, but it is
 * fully operational during normal computer usage.
 *
 * For a less heavy-handed approach, enable NKRO via magic key (LShift+RShift+N)
 * or via bootmagic (hold SPACE+N while plugging in the keyboard). Once set by
 * bootmagic, NKRO mode will always be enabled until it is toggled again during a
 * power-up.

 * Magic Key Options
 *
 * Magic keys are hotkey commands that allow control over firmware functions of
 * the keyboard. They are best used in combination with the HID Listen program,
 * found here: https://www.pjrc.com/teensy/hid_listen.html
 *
 * The options below allow the magic key functionality to be changed. This is
 * useful if your keyboard/keypad is missing keys and you want magic key support.

/*
 * Command/Windows key option
 *
 * If you define this, the thumb enter key becomes the Command/Windows key. There's still an enter key on the right
 * ring finger, so this key is much better utilized as the otherwise nonexistent Command key. I think some newer
 * DataHands let you remap right ring east as Command, but having it on the thumb is nicer. Comment out this define
 * to use the original layout.
