The next several sections cover two of Word's core reviewing features: comments and tracked changes. In Word 2002, Microsoft revamped Word's interface to both features, making them significantly easier to use. If you are upgrading from an older version of Word, you may first want to get comfortable with Word's current reviewing interface before getting into the details of working with comments and tracked changes.
Microsoft sometimes refers to comments and tracked changes collectively as markup.
Word's Reviewing toolbar brings together all commands for marking up a document with comments, tracked changes, and highlighting, as shown in Figure 26.2.
