+ * NKRO may prevent your keystrokes from being detected in the BIOS, but it is

+ *
+ * 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

+ * DataHands let you remap right ring east as Command, but having it on the thumb is nicer. Comment out this define
