Could someone point me to a tutorial or text that explanes in detail the fields
in the trigger set up panel.

The various variables pretriggerID, Reset Id, Recycle time.
and the flags Such as flip trigger, reset trigger, once only.
Ignore scan, ignore click, use sonar.

Thanks in advance

Not sure if there is one or not. Goto your Gstudio folder and then to the template6 >> code. Open the trigger00.wdl with notepad. It is noted well.
