Add a comment
To add an anchored comment, select text, enter the comment in the popover, then select Save. For a Markdown document, select Global comment to add a comment without selected text. The current HTML viewer has no global-comment control. An anchored comment keeps its quoted text. If later edits remove that text, the thread remains in the panel as Unanchored.Reply and resolve
Select Reply to add a one-level reply. Select Resolve when the thread is finished. A resolved thread stays visible and remains in the comment count, but it accepts no new replies until an editor selects Reopen. The panel can collapse older replies behind Show N earlier replies.Comment on a historical version
A pinned?version= view shows the current comment threads in the panel but
does not mark their locations in the old document body. Comments are read-only
in this view. Return to the latest version to comment or resolve.
