Question 1

Does Slack use standard markdown?

Accepted Answer

No. Slack uses its own formatting syntax called mrkdwn, which differs from standard Markdown in several ways. For example, bold uses a single asterisk (*text*) instead of double asterisks, and links use angle bracket syntax (<url|text>) instead of square brackets.

Question 2

How do you bold text in Slack?

Accepted Answer

Wrap your text in single asterisks like *text* to make it bold. This is different from standard Markdown, which uses double asterisks. In Slack, single asterisks always produce bold text.

Question 3

How do you use code blocks in Slack?

Accepted Answer

Use a single backtick for inline code (`code`) or triple backticks for a multi-line code block (```code```). Slack code blocks do not support language-specific syntax highlighting.

Question 4

What is mrkdwn?

Accepted Answer

mrkdwn is Slack's custom text formatting syntax. It is similar to Markdown but has key differences: single asterisks for bold, single tildes for strikethrough, angle bracket links, and no support for tables, images, or syntax-highlighted code blocks.

Format	Syntax	Result
Bold	`text`	Bold text
Italic	`_text_`	Italic text
Strikethrough	`~text~`	Strikethrough text
Inline Code	`code`	Monospaced code
Code Block	```code```	Multi-line code block
Block Quote	`> text`	Indented quote
Ordered List	`1. item`	Numbered list item
Unordered List	`- item`	Bulleted list item
