I want to know what line and file syntax region foo start... was set.

I have tried this:

:verbose syntax foo
:syntax foo?
:verbose syntax foo?

One relatively simple, but still slightly manual, way: use :scriptnames. You can traverse quite quickly with :execute 'args' join(filter(split(execute('scriptnames')), "v:val =~# 'syntax\/'")) - this will open all loaded script files that match syntax/, and the file you want is probably one of these.

@KarlYngveLervåg another way is to use rip grep. Usually you would go in $VIMRUNTIME or in ~/.vim rg 'something'. I just thought there was a command I could use from vim to find out.

I don't think there is (but I'll be glad to learn otherwise). However, there is :verbose highlight Group, which may help if the default highlighting is added in the same file/location.

@KarlYngveLervåg Ya, that's usually where I start. More of then than not the one that does the syntax match is the one that does the highlight also. Not always the case though.
