Formatting and shortcuts

Hover over Show shortcuts (the question-mark icon) at the top of a note to see the most-used Editing shortcuts. Click the icon to pin the panel; press Esc or click outside to close it. See full help → at the bottom of the panel opens this page.

This page is the full reference, including shortcuts and formatting that the panel leaves out.

Block types

Type / in an empty text block, or click + to the left of a block, to open the block menu. Block names in the menu are always in English, in both the Korean and English UI. Only Import PDF follows the UI language.

Block menu name	Block	Summary
`Text`	Text	The basic text block.
`Heading`	Heading	Six levels, H1–H6.
`Unordered List` · `Ordered List` · `Checklist`	List	Bulleted list, numbered list, and checklist. Lists can be nested.
`Quote`	Quote	A quotation with its source.
`Delimiter`	Delimiter	A horizontal line that separates content.
`Table`	Table	Add and remove rows and columns; inline formatting works inside cells.
`Code`	Code	Syntax highlighting for 12 languages: Plain Text, Python, JavaScript, TypeScript, Bash, PowerShell, JSON, YAML, Markdown, SQL, HTML, CSS.
`Formula`	Formula	A block formula written in LaTeX and rendered with KaTeX. Inline math within a sentence isn’t supported.
`Mermaid`	Diagram	A diagram written in Mermaid syntax that you can drag to pan and zoom in and out.
`Image`	Image	Upload an image up to 10MB or paste an image URL. You can resize it.
Import PDF	PDF pages	Inserts the pages you pick from a PDF as image blocks.

For details on each block, see Block types. The AI assistant isn’t in the block menu; open it with Open AI with Space below.

Inline formatting

Select text by dragging to show the inline toolbar. You can apply the following formatting. Bold and italic appear in the toolbar as B and I icons.

Formatting	Shortcut (Windows)	Shortcut (Mac)
Bold	`Ctrl` + `B`	`⌘` + `B`
Italic	`Ctrl` + `I`	`⌘` + `I`
Underline	`Ctrl` + `U`	`⌘` + `U`
Strikethrough	—	—
Highlight	—	—
Link / Source	—	—
Inline code	`Ctrl` + `E`	`⌘` + `E`

Press the same shortcut again, or click the toolbar button again, to remove the formatting.

Links and source chips

Click Link / Source to open the input fields. URL * is required; Type, Title, and Label are optional.

Enter only a URL to create a regular link.
Add a type, title, or label to show a source chip in the text.

Click a link or source chip in the text to see the source details and Open link.

Indenting (Tab / Shift+Tab)

Tab doesn’t open the block menu; it indents.

Text: Tab indents one level and Shift+Tab outdents. You can indent up to one level deeper than the text block above. Press Enter on an indented line and the next line keeps the same depth.
Lists: nests an item one level deeper (Tab) or moves it back out (Shift+Tab).
Tables: moves to the next cell.
Code, formula, and Mermaid editors: inserts two spaces. With several lines selected, it indents or outdents every selected line.

Open AI with Space

Press Space on an empty text line to open the AI assistant input bar right there. The editor shows these hints:

Empty note: Type something or press Space to ask the AI...
Empty line in a note that has content: ✦ Space to continue with AI...

Press Esc while typing a request or while the AI is writing to cancel. On the title line and in blocks other than text (lists, tables, and so on), Space types a normal space. Guests can’t use AI tools.

You can do the same from the AI input bar at the bottom of the editor (Type what you'd like the AI to do… (Space on an empty line)). To review and apply results, see AI assistant block.

Title lock

The first line of a note is always locked as the document title.

The title line can’t be changed to another block type. If you try from the block menu, it switches back to a title.
Typing / on the title line inserts a / character instead of opening the block menu, and Tab does nothing.
Pressing Enter on the title line creates a text line right below it.
If you select several blocks including the title and delete them, the title line stays and only its text is cleared.

Full width

Turn on Full width in the ⋮ menu at the top of a note to widen the body to the full screen width. Turn it off to return to the default width. The setting is saved in your browser and applies to every note you open in that browser.

Keyboard shortcuts

On a Mac, use ⌘ (Cmd) instead of Ctrl and ⇧ instead of Shift.

For basics such as the block menu and block handle, see Editor basics.

Mentioning members

In the body of a published note, type @ followed by a name or email to open the list of members you can mention. Pick someone to insert an @name mention; when the note is saved, they get a notification in their Inbox.

In a regular note, you can mention members of the current workspace.
In a restricted note, only members who can already open that note, plus admins and owners, appear in the list.
You can’t add mentions to a personal draft, and guests can’t create or receive mentions.
A mention that’s already saved doesn’t notify again when you edit other content. If you delete a mention and add it again, it counts as a new mention.
Hover over a mention to see the person’s name and current workspace role. The mention itself isn’t a profile link.
