# **1. In LaTeX**
Use the **`titlesec` package** and adjust the **`secnumdepth` counter** to include an extra level (e.g., `\paragraph`):
```latex
\usepackage{titlesec}
\setcounter{secnumdepth}{4} % Enables numbering down to \paragraph level [[1]]
```
- **Example Structure**:
```
1. Section
1.1 Subsection
1.1.1 Subsubsection
1.1.1.1 Paragraph (new subheading level)
```

# **2. In Microsoft Word**
## **Step 1: Create a New Heading Style**
1. Go to **`Window > Styles > Paragraph Styles`**.
2. Click **`Create New Style`** and name it (e.g., “Heading 4”) [[null]].
3. Format the style (font, size, spacing) to match your hierarchy.
## **Step 2: Update the Multilevel List**
1. Go to **`References > Table of Contents > Insert Table of Contents`**.
2. Customize the table of contents to include the new heading level by adjusting the **`Show Levels`** field to **5** [[notes/0.6/2025/02/7/7]].
## **Step 3: Apply the New Style**
- Highlight the text for the new subheading and select the newly created style (e.g., “Heading 4”) from the **Styles** pane on the **Home tab** [[notes/0.6/2025/02/6/6]].

# **3. APA-Compliant Headings (for Academic Papers)**
APA supports **five levels of headings** [[null]]. For example:
1. **Level 1**: Bold, centered (e.g., “1. Introduction”)
2. **Level 2**: Bold, left-aligned (e.g., “1.1 Methodology”)
3. **Level 3**: Bold, italicized, sentence case (e.g., “1.1.1 Data Collection”)
4. **Level 4**: Bold, indented, ending with a period (e.g., “1.1.1.1. Survey Design.”)
5. **Level 5**: Italicized, indented, run-in before the paragraph (e.g., “survey implementation”).

# **4. Consistency Tips**
- Use **distinct styles** for headings and normal text (e.g., “Heading 4” vs. “Body Text”) to avoid confusion [[null]].
- **Update styles dynamically**: Right-click a formatted heading and select **`Update [Style Name] to Match Selection`** to maintain consistency across the document [[null]].

# **Example Of a 5-Level Hierarchy**
```

1.1 Stateless/Timeless Information
1.1.1 Definition and Examples
1.1.1.1 Timeless Blueprint in Quantum Mechanics [[10]]
1.1.1.1.1 Relationship to Entanglement (APA Level 5)
```
