Compare PDF Files
Reporting all the modifications made to a document is a difficult task if changes weren’t tracked during the editing process. Comparing the new document with its original version is the easiest way to pinpoint every single change that was made. To compare two versions of the same document, convert them to PDF in Nitro Pro and use the Compare tool to identify any differences in text, images, and even annotations.
JavaScript
Copy and paste JavaScript
JavaScripts can be copied and pasted from one field or other location in a PDF document or between two documents. If you examine PDF files for learning JavaScript programming, you can browse PDF files containing scripts, copy a script from a document you download from the Internet, and paste the code into the JavaScript Editor in your document. With a little code modification, you can quickly add scripts to your own files.

Create Bookmarks Automatically
The Auto Build Bookmarks feature can totally automate the creation of bookmarks in your PDFs, and with very little effort greatly enhance the usability of the PDFs you publish. Use it to auto-generate bookmarks based on the font styles (headings, chapters, etc.) and the layout used in your PDFs. You can also use it to build bookmarks based on the textual and numerical content of the PDF files by using the text masking and wildcards features.

You can create bookmarks by selecting text on a page and making it a bookmark, or by adding an untitled bookmark and then setting and naming it in the Bookmarks pane.
Forms
Create a Check Box Field in a PDF
In almost all cases you should use unique field names when creating form fields. If you use the same name for a field, like a text field, data typed in the field box is replicated for all fields with the same name. The exception to the rule is when creating check box and radio button fields. If you want one check box or radio button in a group to be unchecked as another check box or radio button is checked, you use the same field name. Both these field types have an option for adding an export value. When you create fields with the same name, you use different export values to distinguish one choice from another.
Forms
Create a Combo box field in a PDF
Combo Boxes provide users a drop down menu, and only a single response can be selected from this menu. You can add menu items for combo boxes via the Options category in the field’s Properties.
Forms
Create a Text Field in a PDF
The most common field type on PDF forms is the text field. Text fields permit respondents to add alpha text and/or numeric values. You can format text fields in a number of different ways to ensure fields are completed properly. You can add custom format scripts, validate data, assign actions, and perform calculations on text fields.
