I had to use Big Query a few years ago, IIRC there are multiple sections to the screen but it is essentially the same as any SQL tool - queries, results, error panes and similar. That's the web interface though, also IIRC we mainly used sbt which is a command line tool for building up that queries. There are some complexities there with versions and other stuff I frankly didn't understand but the bottom line is that you can use that or other tools so you are only dealing with a terminal, would this make it easier for a screen reader?

@fionasboots It would; thanks for the good info!
