With that mod you’ll be able to use stealth mode just like in Grand Theft Auto V. You won’t have to be crouching for to be not seen. Also when you’re in stealth mode you won’t be standing up immediately after pressing F or execution button to take down NPCs.
C = Stealth mode
X = Stealth animation (Since being in stealth mode prevents you to do some front takedowns, I added this option)
CTRL = Turn back to default animation
Double tap CTRL = Crouch
