Rotation Toolbar
By default, the Rotation toolbar contains tools for rotating PDF pages. Note that this rotates the page, which affects a change to the PDF, not the view. If you rotate the view, it does not change the PDF.
Note: The exact tools a user will see depends on their Profile, licensing, and the customizations they have made and might not include all the tools mentioned here.
The toolbar may be hidden, and you can unhide it by following the steps in the Show / Hide Toolbars article. Below is an image of the toolbar.
Rotate Counterclockwise (SHIFT+ALT+MINUS): Rotates the page counterclockwise in 90° increments.
Rotate Clockwise (SHIFT+ALT+PLUS): Rotates the page clockwise in 90° increments.
Note: The toolbar buttons can also be configured to rotate the current page or all pages in the documents.
