How to Add Comments in Microsoft Word: Windows and Mac Shortcuts

Comments help reviewers discuss a passage without changing the document text. Select text or place the insertion point, choose Review > New Comment, type your note and post it. In Word for Windows, Ctrl+Alt+M commonly inserts a new comment; shortcut availability differs by platform and version.

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.
