Hi Ted and all!
Funny that you should mention coplanar marking right now-- I had been
leaving through old zzdev mails just a few days ago and been pondering
it a bit.

Earlier, you wanted to use d.marklist or d.listmarks for the list of
marking-cells inside a mark (instead of d.1 in your present design).
(This is what I mentioned as d..mark-list in my other mail. Gzz 0.6 uses
this internally, by the way.)

I'd prefer to use the headcell of the mark, simply connecting it where
you need it. Especially when using d..mark-list instead of d.1, its
special connections would not get in the way.

Hm, interesting! So far I had assumed there would be a ringrank of marks
and a current mark, as with the dimension and view lists.
An open question is the set of keyboard commands used for marking.
A few musings about key bindings (hopefully for implementation in Gzz 0.8)--
m: mark current cell in right arrowset
o m ("other mark"): mark current cell in left arrowset
<cell number> m: mark the cell identified by <cell number>
M <dir>: mark half-rank in direction
Ctrl-M: change to next mark set
Alt-M: change to previous mark set
[Note: proposed change of use for 'o' key: perform an action on the cell
in the *other* arrowset, e.g. 'o - l' would connect the cell in the left
arrowset to the right from the cell in the right arrowset; 'o G' would
make the left arrowset jump to the position of the right arrowset. The
current meaning of 'o,' "go to rootclone," could be assumed by the 'r' key.]
On the mark list, there's always one mark that does not mark any cells
yet. To start a new mark, simply Ctrl-M on that mark and start marking
cells. Marking a cell in that mark creates a new empty mark on the list.
BTW, generally, I feel the currently active mark set should be one of a
number of options that can be configured to function keys (amongst
dimensions shown, cursor position, arrowset, active frame, and view).
Thus, I'd like to tell my computer quickly: "F4 is the current set of
dimensions (d.1, d.4, d.mark) and the current mark (m.7)." Then,
pressing F4, I want to change to these configurations (leaving all other
configurations what they were before). I think for me, this could ease
the task of navigating zzstructure considerably.
