Loading a button from the library

I haven’t fiddled with flash in ages (shame on me i know i know, feel bad as it is). Been trying to get back into it learning AS3 using Flex2/CS3 ide.

So far i created a button with an animation in it. Enabled the linkage. Now i can’t for the life of me remember how to load it on stage and duplicate it. Especially since AS3 is different from AS2.

A hand would be greatly appreciated.
