The "minus' button if what you push when you are in full speed cruise
:-) (Try it and see what happens!)

Nice thing about a sim, you can do stuff you CANT do on a real
airplane (like crash).

And that is why a sim will NEVER be like true flight. With a sim, if
you crash, you crashed and you are ok. With a real airplane, you
crashed, and that's IT! No more you. A different headspace, attitude,
whatever you want to call it.
