Once you’ve opened a PDF file, either online or as a separate file, you’ll need to know how to read from and navigate in, the PDF document. It may seem like all you need to do is open a PDF and being reading. But for the most part, we do not read from beginning to end in one sitting as we do with physical books. As digital readers, we jump from page to page, clicking through to other sections
Fortunately, you can customize and aid your digital reading habits with PDF documents. While most PDF viewers, such as Adobe Reader, will not allow users to make many changes to the PDF documents they download, they do, however, offer great tools for navigating and searching through lengthy PDF files.
Adobe Reader will allow users to search for words and other items such as articles, attachments, bookmarks, and comments.
