Once I begin setting editable areas, there are times when I may want to again make that area not editable or slightly change the area that is editable. I do not see how to do that. I see the comments that indicate where editable regions begin and end, but I do not see how to eliminate or change the editable region parameters.

I am not sure how to answer your question directly... but I think I can offer a suggestion that helps you avoid this issue of the parameters.

I always make a one cell table as the editable region... that way it will stretch to fit the area I want it in - or I can easily change the parameters of the cell/table rather than the region itself.
