Whatever the keystroke is for outputting a slice,
here's how it should probably work:
1. Mark all cells, once for each dimension except "cursor."
I.e. with separate mark-cells m.d.1, m.d.2, ...,
all posward in d.mark from the cell.
All the m.d.1 cells are to be connected on d.marklist;
similarly for all the m.d.3 cells, all the m.d.clone cells, ...
a. Now go through the cells marked with m.d.1
till you find a marked cell which is has no neighbor
in -d1. (It is either a negend cell or an orphan, with
no connection in d.1.)
c. Start a new rank on the slice list
(UNLESS this cell has no posward neighbor,
in which case go to a).
d. Remove its m.d.1 mark.
e. Put this cell on the current rank of the slice list.
f. Go posward in d.1 from the current cell.
(If no cell is posward, go to a).
Consider this new cell.
g. Go to e.
2, 3 etc. Repeat for every dimension.
When finished, if I've written this correctly,
you'll have a list including each independent rank
in each dimension and no mark cells left.
OOOOOPS-- forgot about looping ranks.
Left as an exercise for the reader ...
