This edits the document. It is not a view setting — collaborators see it, and it saves
with the file. Inline formatting inside changed paragraphs (links, italics, colour) is
flattened while anchors are on. Remove anchors restores everything exactly, but only
while the snapshot exists. Work on a copy if the file matters.
Just reading, not editing? The
Waylight Reader
cannot touch your file at all.
