Reverse thrust?

Can somebody tell me which keys and how to use reverse thrust on FSX please?

Ron

Move the throttles to IDLE and engage Reverse Thrust with either the F2 key or the button it has been assigned to and hold them down until maximum reverse thrust. To turn off Reverse Thrust either hit the F1 key or quickly move the throttles forward and backward !

Thanks for that, I'll try it out tonight!
