Without using programming, you can right-click on a cell, and select
Pick From List, and select a name from the dropdown list.

Or, using the keyboard, press Alt + the down arrow.

I have a column that will contain names. I'd like to use validation to make

This works fine by defining a dynamic named range of the column as the
validation list. The problem however is that it doesn't give a unique list
i.e. the range is the whole of the column entered so far hence I get
multiple occurrences of the same name.

Does anyone know how I can make this a unique list?
