In HyperCard (and some other systems), if you wanted to support the kind of
functionality you're talking about, then you used "push card" and "pop
card." Whenever you went to a "child" document, the "parent" would do:
push card
go card x
Then when the user clicked on the "go back" button, the script would do a
"pop card" clearing the history list and jumping back to the last pushed
card. This also allows you to lead the user down a sub-tree of several
links, then jump back to the lead off point.
So, I think what you're really talking about is stack based push/pop idea.
