A family of Microsoft word processing software products for creating web, email, and print documents.
There is no explicit command to select all Comments.
What may be useful is:
- Start at the beginning of the document
- Go to Edit> Find> Advanced Find & Replace
- Enter the characters ^a in the Find what: field
- Check the box for Highlight all items found in: Main Document
- Click Find All
That produces a pane @ the bottom of the document window which lists all comments. You can select & copy them there.
There's also the option to print just the Markup by going to the Copies & Pages list, selecting Microsoft Word then choose List of Markup from the Print What: list.
