Because I tend to accidentally enter macro programming mode and mess up my macro.

To program a macro, for example fn+L -> Win+L:

  1. Press Fn + R_Ctrl to enter marco mode. (LED1 will turn solid white) Ctrl
  2. Press Fn + L (LED1 will blink white)
  3. Press Win+L
  4. Press the Pn key once to save the new setting. LED1 will turn solid white again.
  5. Press Fn + R_Ctrl again to exit the macro mode. LED1 will turn off.
