Of all the field types, button fields have the broadest use. You can add buttons on PDF forms to perform a variety of actions associated with filling out a form or you can use buttons on PDF documents not intended for form use. Buttons can be used for items in any PDF such as navigational tools in a PDF design, hyperlinks for a variety of different actions, and just about any other condition that sparks your imagination.

To add a button field:

1. Open the PDF in Nitro Pro.

2. On the Forms ribbon tab, in the Fields group, click Button.

3. On the page, drag the pointer where you want the field to appear.

4. Double-click on the field and do one of the following (depending on your preferences):

• In the Properties context tab, name the field and set its appearance settings.
• In the Properties dialog, name the field and set its appearance settings.

5. Do either of the following:

• If you’re using the Properties context tab, in the More group, click Properties and then Options.
• If you’re using the Properties dialog, click the Options tab.

6. If you want to use an icon appearance or have text appear inside the button, choose the appropriate option from the Layout menu.

7. The Actions tab enables you to select the trigger. By default the Mouse Up behavior is assigned. In most cases you’ll want to leave the trigger action as the default.

8. Assign an action. Open the Select Action drop down menu and choose an action to assign to the button.

To edit a push button form field:

1. Open the PDF in Nitro Pro.

2. On the Form ribbon, in the Form Fields group, do either of the following:

• Click the field type that corresponds to the field you want to edit.
• Click Select Fields.

3. Double-click the field to begin editing its attributes.
