Is there any practical difference between activating an open document by
clicking on its button on the Window menu, and "opening" the already
open document by clicking on its button on the File menu? Is the latter
method slower and less efficient?

Similarly, to activate an already open document from a macro, is there
any difference between

Documents([DocName]).Activate

and

Documents.Open (DocFullName)

Will the macro work less efficiently if I do the second approach?

Thanks,
Larry
