In case it helps,
Ive added a file to the docs here..
http://www.dom3minions.com/docs/
Its called MOD_strings.txt
Its taken directly from the game. That means that
A) it might have the exact wording in places where you cant seem to get it to work
B) it also includes a bunch of error statements so unless someone wants to weed out the actual commands, its bulkier than it needs to be
C) It might be very possible that some of the commands have NOT been announced (and dont work yet) so dont get too excited at what you see
