Track Changes and Comments

Every chapter so far assumed a single author shaping one document alone. Real documents get reviewed, edited, and argued over by more than one person — and Chapter 1's own flowing-text model, where content has no fixed address to point at, makes that genuinely risky without the right tooling. Track Changes and Comments are Word's answer: a record of exactly who changed what, and a way to discuss content without silently altering it.

Turning On Track Changes

Review → Track Changes (or Ctrl+Shift+E) toggles recorded editing on. Once active, nothing you type or delete is applied directly to the document's actual content — every insertion and deletion is instead recorded as its own distinct, visible, reversible edit.

Reading Tracked Changes

Inserted text appears underlined; deleted text appears struck-through rather than actually disappearing — both in a colour Word assigns automatically per reviewer, so several people's edits stay visually distinguishable from each other in the same document. Hovering over any tracked change shows exactly who made it and when, turning a shared document into a genuine, attributable edit history rather than an anonymous pile of changes.

Accepting and Rejecting Changes

Review → Accept or Reject, either one change at a time or via Accept All/Reject All. Accepting a tracked insertion makes it permanent, ordinary text; accepting a tracked deletion actually removes the struck-through text for good. Rejecting either one reverses it completely, restoring the document to exactly how it read before that specific change was proposed.

Comments: Discussion Without Changing the Text

Review → New Comment attaches a note to a specific selection, shown in the margin, without altering the document's actual content in any way. Comments can be replied to (threading a small discussion under the original note) and marked Resolve once addressed — which greys the comment out without deleting it, preserving the discussion for later reference rather than erasing it outright.

Comments vs. Tracked Changes: Genuinely Different Purposes

A Comment is a question or note ABOUT the content — "should this figure be updated?" — that never touches the actual text. A Tracked Change is an actual proposed edit TO the text itself — replacing a word, adding a sentence — that can subsequently be accepted or rejected. Using a comment to say "change this to X" instead of just making the tracked change directly adds an unnecessary extra round trip; using a tracked change for a pure question ("why is this here?") leaves an edit sitting in the document with nothing genuine to accept or reject.

Review Views: Simple Markup, All Markup, No Markup, Original

The Review tab's own view dropdown controls how tracked changes are displayed, without affecting whether they've actually been accepted:

• All Markup — every insertion and deletion shown inline, exactly as described above.
• Simple Markup — a cleaner read, with a small vertical line in the margin marking where changes exist, without cluttering the text itself.
• No Markup — a preview of how the document would look if every currently-tracked change were accepted — without actually accepting a single one.
• Original — the reverse preview: how the document would look if every currently-tracked change were rejected.

Comparing Two Versions of a Document

Review → Compare takes two separate .docx files — say, the version you originally sent out, and a colleague's edited copy that was worked on with Track Changes switched off the entire time — and generates a brand-new document showing every difference between them as proper tracked changes, computed automatically. This solves exactly the situation Track Changes alone can't: recovering a real edit history from two files where no tracking ever actually happened.
