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)** (<i class="zulip-icon
|
|
zulip-icon-math"></i>) 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.

|
|
|

|

|
{!start-composing.md!}
|
|
|
|
1. _(optional)_ Select the text you want to format.
|
|
|
|
1. Click the **Math (LaTeX)** (<i class="zulip-icon zulip-icon-math"></i>) 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.
|
|
|
|
{tab|via-markdown}
|
|
|
|
{!start-composing.md!}
|
|
|
|
1. 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)
|
|
```
|
|
|
|
{end_tabs}

### Copy LateX from a message in Zulip
|
|
|
|
Zulip supports [quoting](/help/quote-or-forward-a-message#quote-a-message),
|
|
[forwarding](/help/quote-or-forward-a-message#forward-a-message), 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 `htmlAndMathml` [output
|
|
mode](https://katex.org/docs/options.html).
|
|
- Allow MathML annotations to be included in HTML copied by the browser (for
|
|
Zulip, this was [a couple lines of
|
|
CSS](https://github.com/zulip/zulip/commit/353f57e518b88333615911f12a031177c46d7fbe)).
