[swfmill] adding an action to an existing button

[Drew S.]

I have an existing swf file that I'm attempting to modify, and I've been 90% successful using swfmill so far.  My current stumbling block is changing a button that previously activated a GetURL action into a button that causes the swf to play fullscreen.  I found the necessary code on this page: http://www.broculos.net/tutorials/how_to_make_a_flash_animation_truly_fullscreen/20080314/en , but I'm having trouble figuring out how to work it into xml.  Please help, thanks ^_^.
