Review Modes
Commentary separates two decisions: the surface you read and the version scope you inspect.
Surface
Previewrenders Markdown as a document.Rawshows Markdown source.
Use Preview for prose review. Use Raw when exact Markdown syntax, source line context, or wrapping behavior matters.
Scope
Latestshows the current selected file.Diffshows the change for the selected file and change set.
Change Sets
Pull request and document diff routes can expose a change-set selector:
All changesshows the combined change.- A commit-specific option shows only that commit's Markdown change.
- Files that do not participate in the selected commit may appear disabled.
- If a commit has no Markdown changes, Commentary shows an explicit empty state.
Raw Word Wrap
Raw latest and raw diff views support word wrap. Keep word wrap on for reading prose source, and turn it off when exact horizontal layout matters.
Comments Rail And Files Rail
Use the Comments control to show or hide the thread rail. Use the file control to collapse or reopen the navigator when you need more document width.
