We’re rolling out a new comments experience in Word with improved keyboard shortcuts as well as improved @mentions and notifications. This experience unifies how comments work across Word, Excel, and PPT.
When this has rolled out to your users, they will see the modern comments experience, which allows them to @mention and post comments without worrying that co-authors will see their comments before they are complete.
Modern comments provides a consistent commenting experience across Word, Excel and PowerPoint. Users will be able to respond to comments directly from an email notification. The new design provides a focused view of comments as well as an optional all comments view via the Comments pane. With the new post model, Ctrl+Enter is a keyboard shortcut for posting comments.
The new experience shows comments to the right of the page by default. This default focused view hides all resolved comments so you can focus on active comments. The Comments button in the upper right corner of your Word window lets you switch to the Comments pane. This shows all comments in the document including resolved comments.
