*
* Keymap array sapce has 18*8 slot, row is designated with A-Q and col with 0-7.
* In this macro KA0 means key at row:A/col:0, KR7 means key at rowR/col7.
* Empty slot of keymap should has KC_NO.For example row:B/col:0 has no key
* so you must define KC_NO in this slot.(from hid_liber/ansi_iso_jis.c)
* Esc key locates at row:A/col:1 so fist argument of macro should say KA1.
* Right arrow key locates at row:Q/col:2 so last argument of macro should say KQ2.

* NOTE: Except above examples, the rest of macro definition is garbage just for place holder.
