Right, knew I could do that - but I was trying to update an old example named "editing columns" in:
http://wiki.wireshark.org/Lua/Examples/

It's woefully out of date, but basically it tried to swap the src and dst column text using a listener tap.
So I was going to fix it to the newer WSLUA API, but discovered one couldn't do this in wireshark, but could in tshark.
I guess I'll just fix it and have it say "works for tshark only". 

Thanks for the info!
