Can someone tell me how to set a range for the last section of a document?
Or as an alternative how to set the range to the section where the cursor is?

Specifically what I need to do is set the last section as a range so I can
make some modifications. First I need to delete the last two rows from a
table in that section (there are two tables, and I need to delete rows 3 and
4 from the second table). Then I need to search for a text string, and
insert some text in front of the original text.

Thanks for any help.
