3 nooby Questions

Hi!

Im new with flash and i have three questions:

1: How do u add sound to ur movie?

2: When i watch my movie in both window and html mode, I cant see the entire stage!

3: When i edit a movie after saving, i can watch the new edited movie in the document by control+entering it, but i must delete the window movie and then save so that it creates a new file to c the new one!

Thanks in advance!
