I am not sure what you mean by a "Customize" button, there isn't/hasn't
been such a button on any of the Headers and Footers toolbars that I have
seen in any version of Word for WIndows. There is however an Autotext
pulldown on the Headers and Footers toolbar that contains a Filename and
Path item that will do what you want.

Alternatively, insert a { FILENAME \p } field either from the InsertField
dialog or by use Ctrl+F9 to insert the field delimiters { } and type
FILENAME \p inside them. Use Alt+F9 to toggle off the field codes.

W2K, Word 2003. The Header and Footer dialog box (View/Header and Footer)
has a Customize button. I want to add a button that puts the filename and
path of the document in the Footer, but I can't find anything in the
Customize dialog that pertains to filename or path. Under what heading
might
it be hiding?
Thanks.
