Enable the Auto-complete options (interactive forms only)
The Auto-Complete feature stores entries that you type in interactive form fields. Auto-Complete then suggests or even automatically enters responses that match your typing in other form fields. The suggestions appear in a pop-up menu, from which you can select a match.
The Auto-Complete feature is off by default, so you must enable it in the Forms preferences if you want to use it.
1. Right-click the document, and choose Page Display Preferences.
2. In the Preferences dialog box, click Forms from the list at left.
3. Under Auto-Complete, choose Basic or Advanced from the menu. (A description of each mode appears at the bottom of the dialog box.)
4. Select Remember Numerical Data if you want to store numbers that you type into forms.
