Comments and Suggesting Mode

Google Workspace

Chapter 3 · Comments and Suggesting Mode

Chapter 2 closed with a genuine concern: editing directly changes what every current viewer sees, instantly, with no private staging area. This chapter is the tool that solves it — Suggesting mode gives you Track-Changes-style safety without giving up Chapter 2's own real-time visibility.

The Three Editing Modes

A mode switcher in the top-right area of the interface offers three options: Editing (direct changes, visible instantly to everyone, exactly as Chapter 2 described), Suggesting (proposed changes shown distinctly, never applied to the actual text until explicitly accepted), and Viewing (read-only).

Suggesting Mode: Google's Own Live Equivalent of Track Changes

Switch to Suggesting mode, then type or delete text as normal. Insertions appear as coloured, underlined text; deletions appear as coloured strikethrough — the exact same visual convention Word & PowerPoint Chapter 6 used for tracked changes. The genuine difference: this is happening inside a live, shared document. Anyone else currently viewing sees your suggestion appear in real time as you type it, clearly marked as a proposal rather than an actual change to the underlying text.

Accepting and Rejecting Suggestions

Small checkmark and X icons appear directly beside each suggestion — the document's owner, or any Editor, can accept or reject each one individually. The underlying concept is identical to Word's own Accept/Reject from Chapter 6; only the mechanism (inline icons rather than a separate Review tab) differs.

Comments: Discussion Without Changing the Text

Selecting text and clicking the comment icon (or Insert → Comment) attaches a note to that specific selection, without altering the document's actual content at all — the identical concept to Word & PowerPoint Chapter 6's own Comments. The genuine difference here: comments can be replied to in real time by anyone currently viewing, and typing @ followed by someone's email address notifies them directly, tying back to Chapter 2's own live, multi-person nature.

Comments vs. Suggestions: The Same Distinction as Word's Own

A Comment is a question or note about the content, never touching the text itself. A Suggestion is an actual proposed edit to the text, that can subsequently be accepted or rejected. This maps directly onto Word & PowerPoint Chapter 6's own Comment-vs-Tracked-Change distinction — nothing new to learn here conceptually, only new names for the same two roles.

Resolving a Comment

Marking a comment thread Resolved greys it out and collapses it without deleting the underlying discussion — the same idea as Word's own Resolve feature, preserving the conversation for later reference rather than erasing it outright.

	Word & PowerPoint (Ch.6)	Google Workspace
Timing of proposed edits	Recorded, reviewed later, asynchronously	Visible live to every current viewer as they're proposed
Visual convention	Underlined insertions, struck-through deletions	Identical — underlined insertions, struck-through deletions
Accepting/rejecting	A dedicated Review tab	Small inline checkmark/X icons per suggestion
Notifying a specific person	No built-in equivalent	@mention by email inside a Comment

This is exactly the tool Chapter 2 promised

Suggesting mode doesn't sacrifice Chapter 2's live, multi-person visibility to get Track-Changes-style safety — it keeps both. Several people can propose suggestions simultaneously, all visible live to everyone currently viewing, each one clearly marked as tentative rather than final, resolving the exact tension Chapter 2's own closing warning box raised.

Forgetting which mode is active recreates Chapter 2's own risk

Intending to propose a tentative change but forgetting to switch out of Editing mode first directly edits the live text every current viewer sees, instantly — exactly the risk Chapter 2 warned about, simply reintroduced by not checking the mode switcher first. Separately, suggestions left unresolved for a long time can accumulate and visually clutter a document for everyone still viewing it, unlike Word's own tracked changes, which are typically all reviewed together in one batch before a document moves forward — it's worth resolving or addressing suggestions promptly rather than letting them pile up.

Hands-On Exercises

Exercise 1

Switch a shared Google Doc to Suggesting mode and rewrite one sentence. Have a second viewer confirm what they see appear in the document while you type, and describe how it visually differs from what they'd see if you had done the same edit in Editing mode instead.

Exercise 2

Add a Comment (not a Suggestion) to a paragraph asking a genuine open question about its content, and @mention a specific colleague's email address inside it. Explain what happens as a result of the @mention, and why a Comment (not a Suggestion) was the correct tool for this specific situation.

📄 View solution

Exercise 3

A colleague meant to propose a tentative rewrite of an entire paragraph but forgot to check which mode was active first, and the paragraph changed instantly for every current viewer with no suggestion marker at all. Diagnose exactly what happened and what single check would have prevented it.

Chapter 3 Quick Reference

Editing / Suggesting / Viewing — the three modes, switched from the top-right of the interface
Suggesting mode — proposed changes shown live to current viewers, never applied until accepted; same visual convention as Word's Track Changes
Comments — discussion attached to a selection, never alters the text; can @mention someone by email for a direct notification
Comment = a question about content; Suggestion = an actual proposed edit — the same distinction as Word & PowerPoint Chapter 6
Resolve collapses a comment thread without deleting the discussion
Always check which mode is active before a large edit — forgetting recreates Chapter 2's own "no private staging area" risk
