You used to be able to click on a city on the oneworld interactive network map and it would show you every other city you could fly to on oneworld. This was very useful for finding possible connections between AAA and BBB when nonstop flights were not available.

Now when I click on a city, it puts it on a list and asks me to choose another city.

What tool can I use to find all cities which have oneworld flights to/from my chosen city?
