Turn off custom errors mode asap

an environment is giving an error, and you need to turn off custom errors mode in the web.config.

Navigate via filesystem, open the file, find the section, edit the section, all by hand? No.

LinqPad to the rescue!

It could stand to have the trace localonly=false feature too, but it's not there yet, feel free to try to add that feature =)
