I'm trying to determine how a series of dropdown lists were created in an
existing Excel worksheet that I'm editing. Row 1, Columns A through G have
dropdowns with extensive lists in each. If I click on Row 1 itself I see the
apparent name of the Row, "Print_Titles". But I cannot determine how the
lists were created and where they reside. This is the only worksheet in the
workbook.

I need to create an additional list - which I want done in the same way as
these.
