Consider a 4 X 3 table (1,1 top left) with cells 3,1 through 4,2 merged.
Select cells 2,3 and 3, 2 (3, 3 if you maintain a column-based coordinate
system).

How can the selection be preserved and reproduced at a later time (i.e.
after the selection has been moved)?

I've tried storing the Start and End of the selection and its range but when
resetting them, the selection wraps around the table encompassing cells
outside the previous selection.

Any suggestions would be greatly appreciated.

Thanks in advance,
John
