Markdown Blocks

Markdown blocks are the primary way to write text, notes, and narrative content in CoPI. They support rich formatting, scientific notation, and embedded images — everything you need to annotate your research alongside code and data.

Text Formatting

Format	Keyboard	Toolbar
Bold	Ctrl+B	B button
Italic	Ctrl+I	I button
Underline	Ctrl+U	—
Strikethrough	—	—
Inline code	—	<> button

Headings

Use H1–H3 to structure your notebook sections.

• Click H1, H2, or H3 in the toolbar
• Or type /heading1, /heading2, /heading3 to apply inline

Lists

Bullet list — unordered items

• Toolbar: bullet list button
• Slash command: /bulletList

Numbered list — ordered items

• Toolbar: numbered list button
• Slash command: /orderedList

Task list — checkboxes

• Slash command: /taskList
• Click the checkbox to mark items complete

Code

Inline code — for short snippets or variable names within text

• Toolbar: <> button

Code block — for multi-line code with syntax highlighting

• Toolbar: square button
• Slash command: /code (inserts a new code block)

Math

Write math notation using standard LaTeX syntax.

Inline math — flows with surrounding text:

The formula $E = mc^2$ describes mass-energy equivalence.

Display math — centered on its own line:

$$
\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$

Both $...$ and $$...$$ syntax are supported.

Tables

Insert a spreadsheet-like data grid with /table (or /data-grid). This creates a dedicated Table block — not a markdown table — with resizable columns and cell editing.

For a simple inline markdown table, type the pipe syntax directly and it will render as a styled table.

Images

Paste or drag an image directly into a markdown block. The image is automatically uploaded to storage and embedded in place.

You can also insert a dedicated Image block via the slash command /image.

Slash Commands

Type / anywhere in a markdown block to open the command menu.

Block commands — insert a new block

Command	What it does
/text	Insert a new markdown block
/code	Insert a new code block
/image	Insert a new image block
/table	Insert a new table (data grid) block

Formatting commands — apply to current line

Command	What it does
/heading1	Toggle H1 heading
/heading2	Toggle H2 heading
/heading3	Toggle H3 heading
/bulletList	Toggle bullet list
/orderedList	Toggle numbered list
/taskList	Toggle checkbox list

Press Esc to dismiss the menu without selecting.

Keyboard Shortcuts

Shortcut	Action
Ctrl+B	Bold
Ctrl+I	Italic
Ctrl+U	Underline
Ctrl+Z	Undo

Block Actions

Each block has a menu (⋯) with additional actions:

• Move up / Move down — reorder blocks in the notebook
• Duplicate — clone the block and its content
• Delete — remove the block

Pressing Backspace at the very start of a markdown block will merge its content into the previous markdown block.
