A couple of questions for the Savage Worlds editor

How do I add another Edge Type?
I can't see anywhere here to add another Edge Type, and I've tried going through the various to find where the current ones are defined with no luck.

Also...

How do I add a +2 to a specific Knowledge skill?
I've tried quite a few code constructs, but I can't quite get it to work.

I can spin through a foreach and find the Knowledge skill I want, but it won't let me use the loop variable in the modification statement. Am I even close?

foreach pick in hero where "thingid.skKnow"
if (compare(lowercase(eachpick.field[domDomain].text),"arcana") = 0) then
perform #traitprof[eachpick,+,2,"Old Family"]
~hero.childfound[eachpick].field[trtNoStack].modify[+,2,"Old Family"]
endif
