I'm sure it's probably around here somewhere, and I've missed it, but is there a list for how to put in the codes for different magic items/spell/monsters, etc?

I know the basic [  something  ]  XXX  [   /something   ] and the like. 

I know designating a modifier value is {{modifier:XXX}}.

My question is, how do I show the Finesse (STR vs DEX) modifier? Say my DEX is +2 and my STR is +1, and I get an ASI and bump STR to +3. How do I show the change in the snippet and attack button?

If you're looking for taking the higher its {{modifier:str,dex}}

Thanks! That is what I'm looking for.

For future reference, though, IS there a place to find the various strings like this?

Thanks, @Donkleberg, you've been a big help!
