Singling out the Signed tab
Options on the Signed tab apply only to the Signature field type. Its com-
mands enable you to specify actions that occur in a form when data is entered
into a blank signature field. You add signature fields to a form in the same
manner as you do other form fields by using the Digital Signature tool. (See
the “Adding Fields to Forms” section, earlier in this chapter, if you need a
refresher.) The Digital Signature tool creates a blank signature field that can
be filled out as part of completing a form. (To find out all about digital signa-
tures, see Chapter 11.)
To configure a blank signature field, click one of the three radio buttons on
the Signed tab:

time it is signed off in the signature field, in essence “freezing” the form at
that moment in time. Select one of three items on the drop-down list: All
Fields, All Fields Except These, and Just These Fields. If you select either
of the latter two options, click the Pick button to open the Field Selection
dialog box, where you choose the fields you want to render as read-only.
Pick a field by selecting the check box next to the field name in the Mark
Fields as Read Only list box. When you’re finished adding fields, click the
