I've seen people use the parachute directly after falling when roping in WWP but I can't do it myself, which is pretty frustrating. They push people when releasing the rope and then fall from a cliff or something and they immediately saves themselves by releasing the parachute. HOW? The Return Key doesn't work (strange?), so HOW do I do?

while the rope is attached to a wall, select the parachute. now when you fall and touch a wall your parachute will automaticaly come out. be careful tho, it only works if you hit a wall or slide on the floor (not the roof) and only if you dont hit it too hard.

always after the para is activated, you can shoot the rope and attempt to connect again, but you will need to arm the parachute again after this.

Many thanks, made my day!
