You can tell excel what macro to use when the user hits the undo button.

That's what this line does:
Application.OnUndo "Undo the ZeroRange macro", "UndoZero"
(from John's sample code)

Can you "tell" Excel to execute the undo code when the user clicks "Undo" or
does it ahve to be a separately executed macro?

You have to keep track of the stuff you did and the stuff you want to be able to
undo.

But macros can do lots that can't be undone. If you delete a file (not move to
the recycle bin), if you format a disk, ....

John Walkenbach explains it in his power programming books.

I've been trying to program an "undo" into a macro I wrote and I am having
trouble finding the resources. Is there an "undo" class/method or do I have
to manually create an undo rountine.

Unless the macro has an undo programmed into it (and most don't), you can close
the workbook without saving and then reopen.

You'll lose any changes since the last save--including what the macro did.

I found that I can not undo my macro operation by just clicking a
button. Does anyone know how to cancel a macro action which is taken?
