# Which Markdown syntax does the editor understand?

Standard Markdown formats live as you type: headings, emphasis, strikethrough and highlight, bulleted and numbered lists, task lists (Tab and Shift+Tab nest any list, checklists included), quotes, dividers, inline code and code blocks with syntax highlighting, inline and block math (KaTeX), and note-links between notes with autocomplete.

The formatting toolbar and its Insert menu add the rest: tables, callouts in nine types that can fold closed, underline, superscript and subscript, text alignment, text and highlight colors, fonts, links, images, and file attachments. Everything round-trips as Markdown: "Show markdown" below any note reveals the raw source, and exports are clean .md files, so nothing you write is locked into a proprietary format.
