Have you ever wondered where a movieclip asset on stage is located in your library? Many times the folder structure that was there to provide organization ends up being an obstacle to you getting to what you are looking for. A quick way to find out where the asset is is by going to your Properties panel (Ctrl + F3) and click the Swap button. The dialog box that pops up will show you nicely where your movieclip is located in the forest of folders.
