Tables, math and diagrams

Tables

Press ⌥⌘T to insert a table. It shows as a grid and stays a Markdown table in the file.

• Tab and ⇧Tab move between cells. Tab in the last cell adds a row.
• ⏎ moves down. ⏎ in the last row adds a row.
• ⌥⌘ with an arrow key moves the row or column.
• ⌥⏎ opens the cell’s menu.
• Esc or ⌘⏎ goes back to the text below.

Tables fill the text column. To fit one table to its content, right-click it and choose Compact width.

Math

Write a formula between single dollar signs, $E = mc^2$, for inline math. For a block, press ⌥⌘B (Math block) or write it between lines of $$. The formula renders in place. With the caret in it, the source shows and a preview follows as you type, errors included.

Diagrams from text

Press ⌥⌘G (Diagram…) and pick a starter: flowchart, sequence, class, state, ER or Gantt. It goes in as a fenced block:

```mermaid
flowchart TD
  A[Start] --> B{Ready?}
  B -->|Yes| C[Ship it]
```

The fence shows as the drawing. Click it, or arrow into it, to edit the text with the drawing kept under it. The drawing redraws a moment after you pause.

Drawings by hand

Press ⌥⌘E (Drawing) to sketch in a full-window whiteboard. It saves as a .excalidraw file in the note’s assets folder, linked from the note. Press Done to return. ⇧⌘⏎ reopens a diagram or drawing from the caret.

Everything here is drawn on your Mac. Nothing is fetched to render it.
