When first introduced to the latest Adobe Acrobat Pro earlier this month, I could not find the zoom function. Today, I found the zoom function near the bottom of a narrow sidebar on the righthand side of documents in process. This also contains the page number the user is on and a way to skip to a different page, the rotate function, and various tools for zooming. This is a great relief. (These tools used to appear at the top of documents in process).
