[PC] How to shut off the car motor

Does anybody know what key on the keyboard turns off the car's engine?

I know it's the left joystick button on the 360 and I think I read it's LB3 on the PS3,

but I cannot find the right key on a PC keyboard. I ask because coming to a stop

and shutting off the engine makes the heat level decrease much quicker while

trying to evade the police.

Also I was wondering if there is any possible way to remap functions that use

the "Right Control" key because my keyboard does not have a Control key

on the right side. I see it mostly after finishing a race where you have choice to

"Skip" or "Apply" a mod you just unlocked. To Apply requires the Right Control

key but there is no option for it or the Ignition when customizing your keyboard

mappings.

There seems to be quite a few keyboard commands that are "hidden" and the

manual makes no mention of any of the keyboard controls much less these

hidden ones some of us don't even know about. A complete list would be nice.

Thank you.
