# Format your message using Markdown Zulip uses a variant of [GitHub Flavored Markdown](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#tables) (GFM) to allow you to easily format your messages. ## Summary To see a summary of message formatting in Zulip, click the A () icon located in the bottom left corner of your messaging box. You can alternatively click the cog () icon in the top right corner of the right sidebar and choose **Message formatting** from the dropdown menu that appears. ![Message formatting modal](/static/images/help/message-formatting-summary.png) ## Emphasis You can surround your text with a combination of asterisks `*` and tildes `~` to emphasize words or phrases in your messages. ### Italics For italics, surround your text with `*asterisks*`. ![Italicized text](/static/images/help/italics-screenshot.png) ### Bold For bold text, surround your text with `**two asterisks**`. ![Bold text](/static/images/help/bold-screenshot.png) ### Strikethrough For strikethrough text, surround your text with `~~two tildes~~`. ![Strikethrough text](/static/images/help/strikethrough-screenshot.png) ### Extra emphasis To add more variety, flavor, and emphasis to your messages, you can combine different styles of formatting. ![Extra emphasized text](/static/images/help/extra-emphasis-screenshot.png) ## Links To include hyperlinks in your messages, you can either enter the link's URL address directly or surround the link's display text with`[brackets]` and the URL address of the link in `(parentheses)` immediately after. ![Link](/static/images/help/link-screenshot.png) Zulip currently does not support image embedding through links. ## Stream Links To link to another stream in one of your messages, you can either type `#streamName` and click the stream name in the popup, or you can start with `#` and surround your message with double asteriks `**`. ![Stream Links](/static/images/help/stream-link-screenshot.png) ## Lists Begin each item in your list with `* an asterisk followed by a space` to include lists in your messages. ![Lists](/static/images/help/lists-screenshot.png) !!! tip "" You can add nested bullets within lists by adding two spaces before each nested bullet. ## Emojis Zulip features a variety of emojis provided by the [Noto Project](https://code.google.com/p/noto/). To include emojis in your messages, surround the emoji phrase with `:colons:`. A dropdown will appear with suggested emojis as you enter the emoji phrase. ![Emojis](/static/images/help/emojis-screenshot.png) A complete list of emojis can be found [here](http://www.webpagefx.com/tools/emoji-cheat-sheet/). ## Mentions To call the attention of another member, you can alert them by typing `@**username**` If you type `@` and then begin typing the user's email address or the user's name, the system will offer you auto-completion suggestions. ![Mentions](/static/images/help/mention-screenshot.png) Typing `@**all**` will alert all users in the stream, and a confirmation message will appear. ![Mention All](/static/images/help/all-confirm.png) For more information on mentions, visit [here](/help/at-mention-a-team-member). ## Status Messages You can send messages that display your name and profile before a string by beginning a message with `/me`. You can utilize this feature to send status messages or other messages written in a similar third-person voice. For example, if your username is **Cordelia Lear** and you send the message `/me is now away`, your message will be displayed as: ![Status message](/static/images/help/status-message.png). ## Code You can surround a portion of code with `` `back-ticks` `` to display it as inline code. ![Inline code](/static/images/help/inline-code-screenshot.png) Multi-line blocks of code are either: - Fenced by lines with three back-ticks (` ``` `). - Fenced by lines with three tildes (`~~~`). - Indented with four spaces. ![No code syntax highlighting](/static/images/help/no-syntax.png) Zulip also supports syntax highlighting of multi-line code blocks using [Pygments](http://pygments.org). To add syntax highlighting to a multi-line code block, add the language's **first** [Pygments short name](http://pygments.org/docs/lexers/) after the first set of back-ticks; as you type out a code block's short name, a dropdown with short name suggestions will appear. !!! warn "" **Note:** You can only specify the language's short name in fenced code blocks. It is not possible to use the syntax highlighter in blocks indented with spaces. ![Python syntax highlighting](/static/images/help/python-syntax.png) ![JavaScript syntax highlighting](/static/images/help/javascript-syntax.png) ![Rust syntax highlighting](/static/images/help/rust-syntax.png) ![C# syntax highlighting](/static/images/help/csharp-syntax.png) ## Quotes To insert quotes, you can either add a greater-than symbol ```>``` and a space before your phrase or submit it as a quote block by following the code syntax highlighting format. ![Quotes](/static/images/help/quotes-screenshot.png) ## TeX math You can display mathematical symbols, expressions and equations using Zulip's [TeX](http://www.tug.org/interest.html#doc) typesetting implementation, based on [KaTeX](https://github.com/Khan/KaTeX). !!! tip "" Visit the [KaTeX Wiki](https://github.com/Khan/KaTeX/wiki/Function-Support-in-KaTeX) to view a complete of compatible commands. Surround elements in valid TeX syntax with `$$two dollar signs$$` to display it as inline content. ![Inline TeX](/static/images/help/inline-tex-screenshot.png) Also, you can show expressions, such as expanded integrals, in TeX *display mode* to present them fully-sized in the center of the messages by fencing them with three back-ticks ` ``` ` or tildes `~~~`, with **math**, **tex** or **latex** immediately after the first set of back-ticks. ![Display mode TeX](/static/images/help/display-mode-tex-screenshot.png)
