So here is an example. I put the macro into a link on the quick reference toolbar and run 1x. I then click on reply in the comment. I then click on my macro link.
You could also add a comment and run the macro without pressing the blue arrow on comment.
Code:
Sub Macro1()
Selection.TypeText Text:="Test Document"
Selection.Comments.Add Range:=Selection.Range, Text:="Hi There"
Selection.WholeStory
Selection.MoveLeft Unit:=wdCharacter, Count:=1
End Sub
I would like to macro to post the active comment and then return to the beginning of the document. Of note, it doesn't look like you can select macros from within a comment.
