I JUST figured that out myself (by trial and error) and logged back in here to let everyone know. Thanks for posting this! If I hadn't been desperate enough to try something, you would have saved my life here.
I learned also that to do it easier, you can just type "viconfig", which will load the config, and upon closing it will kill the cached config file, causing PFsense to reload the new config. Means you don't have to reboot.
