Where does MacOS store remembered Wi-Fi Names? My mac knows about 50-100 different Wi-Fi network names. I'd like to know where they are remembered, I can't find it. I've searched.

I understand that there is a GUI for editing this information, but it is horrible.  I want to know the file where the data are stored. The Apple user interface is horrible because you can't search or sort. I have more than 100 names.
Ah. I finally found it. The file is /Library//Preferences/SystemConfiguration/com.apple.airport.preferences.plist and it's under the KnownNetworks key.
