Code blocks

Insert a code block with /code or Ctrl + Alt + C. Typing three backticks (```) works too.

Choosing a language#

Click the language name in the top-left corner of the block. A picker opens:

• Type to search.
• Move with ↑ and ↓, choose with Enter.
• Esc closes it.

46 languages are supported: Python, JavaScript, TypeScript, Go, Rust, Java, C, C++, C#, PHP, Ruby, Swift, Kotlin, SQL, Bash, PowerShell, HTML, CSS, JSON, YAML, Dockerfile, LaTeX, and more. Plain Text turns highlighting off.

Colours update immediately when you switch language.

Copying#

The copy button in the top right puts the whole block on the clipboard. It briefly turns into a checkmark to confirm.

More options#

Under the three-dot button:

• Wrap code — long lines fold onto the next line instead of scrolling sideways.
• Add caption — a line of explanatory text under the block. Use the same menu to remove it again.

Both settings are saved with the note.

Typing inside a code block#

• Tab indents, Shift + Tab outdents.
• Enter starts a new line rather than leaving the block.
• Pressing Enter again on an empty last line exits the block into a normal paragraph.
• Backspace at the very start turns the code block back into plain text.
• Anything pasted into a code block arrives as plain text, with formatting stripped.

Undo#

Inside a code block, Ctrl + Z and Ctrl + Shift + Z work on that block's own history, so undo only affects that piece of code.
