Clearing the Undo Stack in a Macro

Normally, as you are making edits in your documents, Word keeps track of what you do. Word does this so you can later use the Undo and Redo commands on the toolbar. What if you are developing a macro, however, and you don't want the user to be able to undo changes? In this case, you can use the UndoClear method in your macro, as follows:

ActiveDocument.UndoClear

In this usage, UndoClear wipes out the Undo stack (the list of actions that is remembered by Word) for the active document. Note that this affects only those actions that have been recorded so far; any new actions will be duly recorded and available on the stack.
