Markdown
You write note and card fields in markdown: a widely used writing format that lets you add formatting (bold, lists, headings, links...) to plain text with just a handful of markers. This page summarizes standard markdown syntax; the next page covers what Tsunagi adds on top of it (math, diagrams, media, cloze).
Basic formatting
| What you want | How to write it |
|---|---|
| Bold | **bold text** |
| Italic | *italic text* |
| Strikethrough | ~~strikethrough~~ |
| Inline code | `code` |
Headings
You can write heading levels 1 through 6, from # to ######, depending on
how many # you use:
# Large heading
## Subheading
### Smaller heading
Lists
Use -, *, or + for an unordered list, and 1. for an ordered list:
- first item
- second item
1. first step
2. second step
Blockquote
Putting > at the start of a line makes it a blockquote; consecutive >
lines merge into a single blockquote.
Link and image
[visible text](https://...)

When adding an image, it's more practical to use the editor's media-insert tool instead of typing the file reference by hand. We cover that on the next page.
Code block
Text you write between three backticks (```) becomes a code block; if
you specify a language (like ```dart), syntax highlighting is applied.
Table
Writing rows one after another as |cell|cell| is enough: unlike some
markdown tools, you don't need a separate ---|--- separator line above
them.
Horizontal rule
Three or more hyphens (---) alone on a line create a horizontal rule (a
section divider).
How preview works
The text isn't rendered live as you type. Instead, every field has a preview button in its top-right corner. Tapping it shows the field's fully rendered output instead of the raw text you typed; double-tapping the preview switches back to edit mode. So you see plain text while writing, and check the rendered version with a single tap whenever you want.
