Hey there and thx.
i Zgooed a bit and found this:
ZO_ChatWindowTextEntryLabel:GetText()
there you may filter it out.
i Zgooed a bit further and then i Found this one:
ZO_ChatWindowTextEntry["system"]["currentTarget"]
the last one seems to be the one i need, because its the current Target you are writing to.
But i will test the one you posted as well
TY
Edit: Tested the one you posted, but i dont get anything out of it ;/
