If you dive on a function name, TotalView displays the function in the Source Pane. After you've looked at what you want to look at, the "undive" button lets you return to where you came from. You can find this button immediately above and to the right of the Source Pane.

After you dive on a function, TotalView adds a chevron (">") to the left of the function name. For example, the four chevrons in this figure show that I've dived four times. So, pressing the "undive" button four times gets me back to where I started.

The Variable Window also has an undive button that does the same thing for variable information.

Release 6.0 Feature

Release 6.0 adds a "redive" button that restores the results of a dive operation. The "redive" button is to the right of the "undive" button.
