How to extract and/or delete a substack from a main stack (v4)

[kee nethery]

Correction and simplification:

To extract a substack (stackB) from a main stack (stackA), view the 
main and substack in the application browser. Select the substack in 
the application browser. Under Windows, right click on the substack, 
under Mac OS X, control click, and select "Top Level" from the popup 
menu. This will open the substack stack window. With the substack in 
the foreground, in the File menu, select "Move Substack to File ..." 
and you have extracted the substack. This saves the substack as a 
separate stack and it removes it from the main stack.

To delete a substack without saving a copy of it, instead of selecting 
"Top Level" in the Application Browser, select "Delete Substack".
