Our custom code fence parser for Python-Markdown does not nest fenced code blocks inside list items, but it can be done with 4-space indented code blocks, as long the list item itself also uses 4-space indentation.

Insert LaTeX formatting
Zulip's compose box has a smart Math (LaTeX) () button, which inserts contextually appropriate LaTeX formatting:
- If no text is selected, the button inserts displayed LaTeX (````math`) formatting.
- If selected text is on one line, the button inserts inline LaTeX (
$$) formatting. - If selected text is on multiple lines, the button inserts displayed LaTeX (````math`) formatting.

-
(optional) Select the text you want to format.
-
Click the Math (LaTeX) () icon at the bottom of the compose box to insert LaTeX formatting.
!!! tip ""
You can also use the **Math (LaTeX)** (<i class="zulip-icon zulip-icon-math"></i>)
icon to remove existing LaTeX formatting from the selected text.

{!start-composing.md!}
-
To use inline LaTeX, use double dollar signs (
$$) around the text:$$O(n^2)$$To use displayed LaTeX, use triple backticks and the word math (````math`) followed by some text and triple backticks at the end:
``` math \int_a^b f(t)\, dt = F(b) - F(a) ```

Copy and paste formatted LaTeX
Copy LateX from a message in Zulip
Zulip supports quoting, forwarding, or copying math expressions, and pasting them into the compose box.
!!! tip ""
If you select part of a math expression to copy, Zulip will automatically
expand your selection to copy the full expression.
Copy LaTeX from an external website
You can copy LaTeX from many third-party sites that use KaTeX, and paste it into Zulip.
!!! tip ""
If copy-pasting math from a website isn't working, consider contacting the
website's administrators with the information below, as it may be an easy fix.
This feature is powered by KaTeX's MathML annotations, which embed the original LaTeX source in the HTML for a math expression. For it to work, the website needs to:
- Generate math expressions using KaTeX in the default
htmlAndMathmloutput mode. - Allow MathML annotations to be included in HTML copied by the browser (for Zulip, this was a couple lines of CSS).
