Bookmarks span ranges, which means you can retrieve their start & end points. For example:
Code:
Sub Demo()
With ActiveDocument.Bookmarks("Bookmarkname")
MsgBox .Range.Start & vbTab & .Range.End
End With
End Sub
However, in a document subject to editing (as the risk of inadvertent deletion or even just updating the bookmarked content as per the 'UpdateBM' code in your other thread (
https://www.msofficeforums.com/word-...out-loops.html) evidences), those start & end points are liable to change with every keystroke. Consequently, retrieving their locations is only valid for that instant.
