Text Formatting

Use asterisks or underscores for italic and bold text. Combine them for bold italic.

*italic* or _italic_
**bold** or __bold__
***bold italic*** or ___bold italic___

Wrap text in double tildes to apply strikethrough formatting.

~~This text is struck through~~

Use the ==text== syntax to highlight text with a colored background. This is useful for drawing attention to key terms or phrases.

This is ==highlighted text== in your document.

Superscript and subscript are supported using caret and tilde syntax. This is useful for mathematical notation, chemical formulas, and annotations.

H~2~O (subscript with single tilde)
E = mc^2^ (superscript with carets)
CO~2~ emissions
x^n^ + y^n^ = z^n^

Wrap text in single backticks to display inline code. This applies a monospaced font and a subtle background, useful for referencing variable names, commands, or short code snippets.

Use the `npm install` command to add dependencies.
The `template_id` parameter accepts any valid template ID.

Add footnotes with a reference marker in the text and a definition at the bottom of the document. Footnotes are rendered as numbered superscripts with links to the definitions.

Unmarkdown supports GitHub Flavored Markdown[^1] with several extensions[^extensions].

Content continues here as normal.

[^1]: GFM is a superset of CommonMark maintained by GitHub.

Footnote labels can be numbers or text. The rendered output always uses sequential numbers regardless of the label used in the source.

Display keyboard shortcuts with the <kbd> HTML element, which renders as styled key caps.

Press <kbd>Ctrl</kbd> + <kbd>S</kbd> to save.
