how do you unhide the "Bookmarks filename" field (BookmarkDB)

[Database Administrator]

We're using Notes 7.02 and I need to unhide the "Bookmarks filename"
field (BookmarkDB field in designer). By default in this version it is
hidden, but I can see it on the Locations form plain as day via
designer. Just can't see where or how to unhide it.

says to create an agent to change it so that it will be unhidden, but
I can't figure out how to do that either (i'm used to creating agents
that run when mail arrives, to maybe move it to a folder or
something.. no idea how to change a form value via an agent). Any help
will be MUCH appreciated. (BTW... this field is found via Location
preferences - Advanced tab - Basics tab. It is within the names.nsf
database.)

I'm fairly new to Notes admin and programming (WAY more use to
Exchange and MS platforms/programming), but can hammer my way through
with good directions.
