Have a nose inside the AnimGraphs and AnimGraphsGE folders in the Library folder in the main directory.
The .dat files are for each crewmember's animation - the triggers are in there.
See if you can get a hold of Ducimus - he'll have a shrewd idea as to what to edit.
IIRC, most of the triggers in SH4 are borked - I know there have been attempts to get the sound man to report correctly, but not with much success.
