It seems that there are several templates attached to this sheet. Both PC and NPC. It's all really new so not all the fields and tags are known, well to the general public yet.
PCs:
@{CHARACTERNAME|wtype}&{template:simple} {{rname=}} {{mod=}} {{r1=}} @{CHARACTERNAME|rtype}+[[@{CHARACTERNAME|ROLLBONUS}]][LABEL]]]}}

Basic rolls
@{CHARACTERNAME|wtype}&{template:atk} {{mod=}}
{{rname=)}}
{{rnamec=CRIT}}
{{r1=}} @{CHARACTERNAME|rtype}cs>20 + BONUSES]]]}} {{range=}} {{desc=}}

This lets you click for damage
@{CHARACTERNAME|wtype}&{template:atkdmg}
{{mod=}} {{rname=}} {{r1=}}
@{CHARACTERNAME|rtype}cs>20 + BONUSES]]]}} {{attack=1}}
{{range=}} {{damage=1}} {{dmg1flag=1}} {{dmg1=}}
{{dmg1type=}} {{dmg2=}}} {{dmg2type=}} {{crit1=}}
{{crit2=}} 0 {{desc=}}

Rolls damage with attack
@{CHARACTERNAME|wtype}&{template:dmg}
{{rname=}} {{range=}} {{damage=1}} {{dmg1flag=1}}
{{dmg1=}} {{dmg1type=Lightning }} {{dmg2=}}} {{dmg2type=}}
{{save=1}} {{saveattr=}} {{savedesc=}} {{savedc=]]}} {{desc=}} {{hldmg=[[(1*?{Cast at Higher Level? Use
Zero for a normal cast. How many levels?|0})d6]]}}

For spells including higher level casting
NPCs:
&{template:npc} {{normal=1}} {{name=}} {{rname=}} {{mod=}}
{{r1=}}

Simple output, not following whisper settings
@{CHARACTERNAME|wtype}&{template:npc} {{normal=1}} {{name=}} {{rname=}} {{mod=}} {{r1=}} @{CHARACTERNAME|rtype}+[[BONUSES][LABEL]]]}}

Follows whisper and roll settings
@{CHARACTERNAME|wtype}&{template:npcatk} {{attack=1}} {{damage=1}}
{{dmg1flag=1}}
{{name=}}
{{rname=}}
{{rnamec=CRIT}}
{{r1=}} @{CHARACTERNAME|rtype}+(BONUSES)]]}} {{description=}}

Click for damage
@{CHARACTERNAME|wtype}&{template:npcatk} {{name=}} {{rname=}} {{rnamec=}} {{r1=}} @{CHARACTERNAME|rtype}+(+0)]]}} {{description=}}

No autoroll for damage (Attack rolls show =
BUG)
@{CHARACTERNAME|wtype}&{template:npcaction} {{name=}}
{{rname=} {{r1=}} @{CHARACTERNAME|rtype}+(BONUSES)]]}}
{{dmg1=}} {{dmg1type=}} {{dmg2=}} {{dmg2type=}} {{crit1=}}
{{crit2=}} {{description=}}

Autorolls for damage
That's the basics that I have found.
I came up with this to output the NPC traits
/w gm &{template:npcaction} {{name=@{selected|npc_name}}} {{rname=@{selected|repeating_npctrait_$0_name}}} {{description=@{selected|repeating_npctrait_$0_desc} }}

Happy gaming and post any more you figure out yourself.
