This ribbon contains the following groups and tools, from left to right:
Zoom group
Zoom In and Zoom Out: Zooming moves typically between 25, 50, 75, 100, 125, 150, 200 and 400%.
Loupe View: View a page area at extreme magnification.
Dynamic Zoom: Move cursor up to zoom in, down to zoom out.
Use the drop-down list of the Zoom to control to move to a magnification value (as listed above) or type in your own value.
Page view group
Scroll Options: Choose a display style from the drop-down list; see single pages, all pages in a scroll with one or two pages horizontally.
Page Fit Options: Set pages to appear at a fixed magnification or zoom to remain fitting in the document panel when it is resized, either with the width or with the whole page always remaining visible.
Full Screen: Display the current document in the full screen with only three controls: Next page, previous page and Exit Full screen.
Rotate view: Temporarily rotate the page view 90% to left or right. This rotates only the page view; it does not rotate the real PDF page: for that use Home > Pages > Rotate.
Previous View, Next View: Return to previous views of the current document. Once this is done, use Next View to move forward in the views.
Note
The View bar also offers a Full Screen tool, and two most useful viewing options:
Fit to page and show single pages.
Fit width and scroll pages continuously.
New group and tool
New Window: Open a copy of the current document in a new window, allowing it to be modified and saved to a new name. To create a new empty document, use File > New > Blank PDF.
Current Window group
Horizontal, Vertical and Quad Splits: Splitting a document view is typically useful for transferring content from one part of a document to another. Click a tool again to remove the split.
All Windows group
Cascade, Tile: Arrange all open document windows in a cascade, or tiled horizontally or vertically.
Close All: Close all open documents, prompting to save any changes, but keeps the program window open with no document loaded.
