Your First Look¶
Once Loud Outline is enabled, nothing changes about your file explorer until it finds something to show you.
- Open a note that has at least one heading — any level.
- Look at that note's row in the file explorer. A small collapse arrow now sits to the left of the filename, just like the one on a folder.
- Click the arrow (not the filename — that opens the note). The note's headings appear as indented
rows underneath it, nested by level: an
H2sits under theH1above it, anH3under thatH2, and so on. - Click a heading row. If the note isn't already open, it opens; either way, the cursor jumps straight to that heading.
- If the note has any headings with their own subheadings, or any tasks/lists, you'll see further arrows nested inside — expand as deep as you like. Everything starts collapsed, so a big note doesn't flood the sidebar the moment you open its first-level arrow.

Try it with a checklist¶
If Show tasks and lists is on (it is, by default — see Settings Reference), add a checklist under one of that note's headings:
## Groceries
- [ ] Milk
- [x] Eggs
- [ ] Free-range, if they have them
Expand that heading in the tree and the checklist appears underneath it, checked items shown struck-through — including the nested sub-item, indented one level deeper again. Click any of them to jump straight to that line.

- Headings in the Tree covers nesting rules in full.
- Tasks and Lists covers exactly where a list or task ends up when it isn't directly under a heading.
