If you wish to have more than one dive level visible at the same time rather than having a dive replace the existing window’s data, you can create a duplicate window.
1 Undive
Click the Undive arrow to return to the initial Variable Window.
2 Launch a new window
Right-click on the array and select Dive in New Window. Another window launches. Now, you can see both the original window and the new, nested dive.
3 Duplicate a window
Alternatively you can create a duplicate of a window.
Select the command Window > Duplicate to duplicate the active Variable Window and then dive to the desired level in a new window.
