It turns out, "git grep" does not go into submodules
I was doing:
$ git grep -i 'allows you to assign a data source'
$ git grep -i 'allows you to assign a data source' -- helpcontent2/
This got me going:
$ cd helpcontent2 && git grep -i 'allows you to assign a data source'
Are the identifiers like id="par_id3154206" essentially random (and I
can just put other random ones for new paragraphs), or do they have
some hidden meaning (and then please explain me how to generate the id
for a paragraph I'm adding).
Thanks in advance,
