Ok i need someone who can explain things in dumb language as something has been buggging me for ages

Most of todays supercars lambo-ferrari etc all seem to have these f1 type paddle shifts thingeys..how do the fookas work though?..is there a clutch aswell or do you simply flick the paddle without touching a clutch?

What happens when the car is brought to a standstill at traffic lights etc as in a normal manual we would just simply press the clutch down how is the car brought to a stop without moving, without a clutch?

It may be a stupid question i know but ive always wondered how those paddle thingeys work

im bored,cant u tell
