View.ShowComments Property (Word)
True for Microsoft Word to display the comments in a document. Read/write Boolean.
If revision marks are displayed in balloons in the right or left margin, comments are displayed in balloons. If revision marks are displayed inline, the text to which comments apply is surrounded by wide-angled square brackets; when a user places the mouse pointer over the text within the brackets, the related comment is displayed in a square balloon directly above the mouse pointer.
