Ducky One TKL three lights (C S M) Alt + Shift for S

[Quardah]

Hello folks i need some help identifying the LED behaviours on one of my keyboard. It's a Ducky One TKL DKON1687. In the manual it's the pink with no LEDs (Page 26):

I started using it again and i notice that the three typical top-right lights have inconsistent behaviors. They are labelled C S and M. My inquiry is mostly for the S.

The C is Caps Lock.
The M is Mouse Mode (Page 39).

But the S doesn't turn on if i click Scroll Lock. It turns on if i do LeftAlt + LeftShift (?) I noticed this because i use that combination in Linux to switch between US and FRCA layouts.

Also when on it doesn't seems to be making any differences in between having it on or of.

The only thread i found on reddit mmkb is worthless:
https://www.reddit.com/r/MechanicalKeyboards/comments/9i0m9o/quick_question_c_s_m_lights/

And the documentation is insufficient.

So maybe one of you know why it behaves like this and could explain it so there's a definitive answer out there.

Thanks.
