Comment versus Track Changes
A comment adds a discussion thread, while Track Changes records insertions, deletions and formatting changes. Use comments for questions or feedback and Track Changes for edits that require acceptance or rejection. Modern Word may display comments in a side pane rather than traditional balloons.
Reply, resolve and delete
Use Reply to keep related discussion together. Resolve a thread when the issue has been addressed; resolving is different from deleting the comment. Before distributing a document externally, review comments and tracked changes for sensitive information.
Keyboard shortcut troubleshooting
On Windows try Ctrl+Alt+M; on Mac consult the Review ribbon and Word’s current shortcut list, as key assignments can differ. If the cursor is in a protected document or editing is restricted, commenting may be unavailable. For more review settings, see comment balloon customization.
