Rev puts up a cell-sized field over the clicked "cell" so that you can
edit the contents. When you are done editing, Rev puts the new content
back into the relevant item chunk in the field and removes its own
field. The field is temporary. The reason you can't retrieve any
click/selected/text chunking info is because Rev is trapping all that in
order to process the text and pop it into its editing field.
If you don't use the cRevTable cells option in the inspector, none of
that will happen and you can manage the field text and trap selections
