Pushes the Source Pane’s dive stack so that you return to places you “undove” from. The dive stack is a history of the source locations you have visited while examining information. This command is analogous to the “Forward” button in a browser in that it returns you to a position you previously returned from. Each time you “redive”, you push one level back onto the dive stack.

As an alternative, you can select the “>” icon above and to the right of the Source Pane’s title.

For additional information, see View > Undive.
