Formatting

C3NTR supports a range of formatting options to help you write clear, structured articles. You can use the floating toolbar in Rich Text mode, or type Markdown syntax directly.

Text styles

• Bold — Tap B on the toolbar, or wrap text in **double asterisks** in Markdown mode.
• Italic — Tap I on the toolbar, or wrap text in *single asterisks*.

Headings

Three heading levels are available:

• H1 — The largest. Used for the article title (first line). Markdown: # Heading
• H2 — Section headings within the article. Markdown: ## Heading
• H3 — Sub-section headings. Markdown: ### Heading

In Rich Text mode, tap the heading button on the toolbar and choose a level.

Lists

• Bullet list — Unordered items. Markdown: - Item
• Numbered list — Ordered items. Markdown: 1. Item
• Checklist — Items with checkboxes. Markdown: - [ ] Item

Blockquote

Use blockquotes to highlight a key idea or quotation. In Markdown mode, start a line with >. In Rich Text mode, use the toolbar button.

Code block

Wrap technical content or examples in a code block. In Markdown mode, use triple backticks (```) before and after the block.

Horizontal divider

A thin line that separates sections of an article. In Markdown mode, type --- on its own line.

Links

Add an inline link by selecting text and tapping the link button on the toolbar. In Markdown mode, use [link text](url).

Slash commands

Type / at the start of a new line to open a quick-insert menu. This works in both Rich Text and Markdown modes.

Available commands:

• /h1 — Heading 1
• /h2 — Heading 2
• /h3 — Heading 3
• /bullet — Bullet list
• /number — Numbered list
• /check — Checklist
• /quote — Blockquote
• /image — Insert image
• /divider — Horizontal rule
• /code — Code block

Markdown mode

If you prefer writing in Markdown, toggle it from the title dropdown menu in the editor. The content stays the same, but you see and edit the raw Markdown syntax instead of the visual formatting. Your preference is saved between sessions.
