Does MS Word have an "unsaved changes" indicator?
One way to know if a document has unsaved changes is by looking at the redo button.
This icon/button dims out if the file has no changes since it was last saved.
Reliable method: asking Word directly.
Let's get saved status directly from place where it is stored.
Create custom macro with single command:
MsgBox "Saved: " & ActiveDocument.Saved
When you run it (using toolbar icon or keyboard shortcut), it will show you the status right away.
