Thank you for the feedback, I am afraid I will need to work again at
it, in order to create a systematic bug reporduction.

What you wrote confirms my gut feeling. I came to this conclusion as I
was thinking how to implement functions such as row transposition.

FYI, AFAIK, the cell already contains the corresponding symbol, and the
(row, col) coordinates can be derived from the symbol through the
ses-cell symbol property.
