I suggest using MindArchon\\\'s trigger duplicator
http://www.staredit.net/index.php?download=4086The only drawback is its slightly odd syntax, but there\\\'s a help file that explains everything.
You can either save the triggers directly into the map you are working on, OR using the awesome flexibility of SCMD2\\\'s trigedit you can save the triggers into one map, and then copy and paste them into the other map. This is if you want to place them somewhere other than at the very bottom of the triggerlist, or if you want to do any editing in notepad using its equally useful replace function.
Using the right tools and an efficient triggering method, mapmaking does not have to be as tedious as it used to be.
