Hotkey setup

Having a little problem, i reset my hotkeys by mistake, got most back to normal but i cant for the life of me find how to change how to fire when im looking threw my Binoculars. Well it wants me to double tap the Binoculars button want i had it to the sniper button (shift) before, Any one know how i can chnage this back to the sniper button?

Also in hotkeys i have “commander fire control” set to left mouse button+shift but hasnt changed it
