(Not only for Nitecore, but also for all other flashlights with digital switch.)

When the light is OFF, you have 3 possibilities:

- Single click Mode 1

- Double click Mode 2

- Triple click Mode 3

When the light is ON, you have 2 possibilities:

- Single click Turns the light off

- Double click Cycles through the three modes

Of course, all three modes can be programmed individually by a hidden combination (i don't care, what combination exactly).
