best bet is to open the campaign level in the editor and snoop around the triggers yourself.
(and i mean that... you looking at the campaign triggers is far better than me or anyone else trying to explain them, as you can browze at your own lenght.)
playing the level then going into the editor will make the map available throught the top left menu, then its should be the top of the recently loaded files.
