- Creating notes with wikilinks or internal links
- Adding embeds for notes, images, audio, or PDFs
- Using callouts (info boxes, warnings, tips, etc.)
- Managing frontmatter/properties in YAML format
- Working with tags and nested tags
- Creating block references and block IDs
Basic Formatting
Paragraphs and Line Breaks
Paragraphs are separated by blank lines. Single line breaks within a paragraph are ignored unless you use:
- Two spaces at the end of a line
- Or use
<br>for explicit breaks

[[#Heading in Current Note]]Block References
[[Note Name#^block-id]]
[[Note Name#^block-id|Display Text]]
[[#^block-id]]Creating Block IDs
Add a block ID at the end of any paragraph or list item:
This is a paragraph you can reference. ^my-block-id
- List item with ID ^list-blockEmbeds

> [!warning]
> This is a warning callout.
> [!tip] Custom Title
> This callout has a custom title.Callout Types
