The File menu groups common controls to open, save, print, optimize, and send a PDF file.
The Quick Access Toolbar is your customizable area for controls you use most frequently, making them available at all times even as you switch between different Ribbon tabs.
For more information, see The Quick Access Toolbar.
The Nitro Pro Ribbon is designed to be intuitive to anyone familiar with Microsoft Office 2016 software, and provides sets of tools grouped into tabs based on the task they perform.
for example, if you wish to add comments and notes to a PDF, on the Review tab, in the Markup panel, select Add Note.
The Find bar provides a quick way to search for keywords or phrases inside your PDF file. You can also restrict the results to be case-sensitive or whole words only.
for more information, see Search and find text.
Document Notifications will appear automatically to inform you when special features of a PDF file need your attention. For example, if a document is encrypted, or contains interactive form fields, the Information bar lets you know as soon as you open the file.
All PDF file viewing and editing is done in the Document Pane, which lets you work with multiple documents by using a system of tabs (as commonly seen in web browsers), which can also be organized into horizontal or vertical tab groups.
For more information, see: Multiple documents in parallel view.
Quickly change the zoom level of the PDF file to enlarge or reduce the size of the page view. You can control the zoom level by adjusting the slider, or by entering a percentage value up to 6400%. Page View controls let you specify how many pages are shown on screen.
Use these buttons to scroll through pages of your PDF file, jump to the beginning or end of a document, or retrace your steps forward and backwards through your viewing history.
