Caliu renders your markdown in place, hiding the syntax as you type. Source mode lifts the curtain: it shows the note exactly as it is stored, every #, *, and backtick included.
Switching to source mode
- In the web app, open the note's menu and choose Source mode, or press
Cmd/Ctrl+Shift+M. The note becomes a plain text view of its markdown. - On iPhone, iPad, and Mac, choose Source Mode from the note's actions menu. The raw markdown is shown in monospace with syntax highlighting, and no tokens are hidden.
You can keep editing while in source mode; your changes save just like in the rich editor. Switch back by choosing Rich Editor from the same menu (or the same shortcut on the web).
When it is useful
- Fixing markdown that is not rendering the way you expect.
- Copying a note's exact markdown somewhere else.
- Making precise edits to tables, links, or frontmatter without the rendered layer in between.
Notes shared with you offer a similar raw view: the shared note viewer has a View raw Markdown toggle.
