3. Stop for ~1.5 seconds (configurable in Settings) — the engine recognizes automatically
4. The result renders as a KaTeX preview; the LaTeX source is editable below
5. Click "Confirm and insert" — the formula enters the composer as \[ ... \] and renders inline
6. Click "Clear" to start over, "Undo" to remove the last stroke

2. Screenshot OCR

3. LaTeX syntax editor

1. Click "LaTeX syntax editor" in the menu — a dock panel expands below the input row

3. Click any button to insert the corresponding LaTeX code into the editor
4. A live KaTeX preview renders on the right
5. Click "Insert" — the formula enters the composer as \[ ... \]

Inline rendering

Any \[ ... \] you type (or paste) in the composer renders inline as a formula. For example, typing \[x^2 + y^2 = r^2\] renders the equation directly.
