Hi,
say that I, for educational purposes, want to use \showframe for a couple
of pages, and then want to hide the frames. What is the correct way of
doing this? I have for now added a \begingroup and \endgroup, but then
another document parameter that is set inside is cancelled after the
\endgroup.
I tried to look in the source, but could not find anything that worked
(what I tried with was to use \setupbackgrounds[state=stop], but that was
merely a guess, and it did not work).
