     c. Setting full LED brightness using macro

• KEY_LED_UP : getting brighter

• KEY_LED_DOWN : getting darker

     d. Mapping keys for brightness

• A.87 and MX-mini series : FN + - / FN + =

• Thumb series : FN + R Alt/ FN + R Ctrl

    e. 4 Layer Key Map

• 1 : normal

• 2 :  FN

• 3 :  FN2/FN3

    f.  Scroll Lock LED signal
