Cloning objects

Can someone explain to me perhaps how to clone an object so that is is exactly in the same position. I know you can use mirror,, but is there an easier way?

If you're talking about the 'Mirror' button.. that can cause problems. I've yet to find a use for it while modeling for FSX.
