' Before running this example, open a text document.
Dim objSel As TextSelection = DTE.ActiveDocument.Selection

' the insertion point. We begin by selecting the word before
' the insertion point.

' the beginning of the document.

' past the following word.

' The previous call to WordRight may have skipped some
' white space instead of an actual word. In that case,
' we should call it again.

End If
' Insert the new text at the end of the selection.

' text selection.

End If
' Insert the text, overwriting the existing text and leaving the
' selection containing the inserted text.
