You may have noticed that some protocol Reports have links to other Report Windows within them. For example the Predict Humanizing Mutations protocol's Report has links at the bottom to the VH Interactive Residue Analysis Report and the VL Interactive Residue Analysis Report. But once you click on one of these links the window is replaced with the new report contents and you may find yourself trying to get back to the original Report. That's where the Navigation toolbar comes in handy. Note, this toolbar isn't displayed by default so you will need to go to the View > Toolbars > Navigation to see it in your visible toolbars. It will look the the image below and contains four tools to help you navigate back and forth through linked reports.
