Yes, that sounds right.

Well, as I understand it the idea is to have the first cell in each
mark group linked to the next mark group in d.marklist, so that you can
step through all the mark groups.

Once marking on a given group is terminated you presumably increment the
mark group number for next time.  The current mark group number probably
needs to be stored in a system cell somewhere.  Then there also needs
to be a way to modify existing marks.
