Although the hyphenation values you select in the Form Properties and Options dialog boxes apply to the text in the entire form, you can use the Hyphenate option in the Paragraph palette to add or remove hyphenation in individual paragraphs. Use the Hyphenate option to manually adjust text layout on an object-by-object basis.
You can hyphenate the text in the caption area of objects such as text fields, decimal fields, and numeric fields, and the value area of text field objects (default text and text the form filler enters).
When the Hyphenate New Items is selected in the Options dialog box on the Formatting page, the Hyphenation option is automatically selected with new objects added to a form.
