I am sorry if those questions are asked very often, i got a SCG grip a few days ago and i would like to assign the pinky button (button 5) to shift modifier (if i press the pinky button, it should act as a shift modifier). I searched on multiple topics about this and read the manual but i couldn't get it to work, for example i tried this :

I also tried some other things but i am surely doing all wrong. Can someone tell me how to do it please ?
PS : I am using it for DCS and i am currently in Red Led mode (it doesn't go to green when i press it, i know that i have to set it up but i don't know if it has something to do with button mapping ).
