Default Track Selection documentation update?

[preserve]

Can't believe I didn't investigate these settings until now. This feature is awesome!

Mentions part of the default setting as "+sel:(favlang|nolang)"

However, as of at least 10.1.2, this part of the default setting is now "+sel:(favlang|nolang|single)"

As far as I can tell, I don't see the "single" option documented:
