Zulip uses Markdown to allow you to easily format your messages. Even if you've
never heard of Markdown, you are probably familiar with basic Markdown
formatting, such as using * at the start of a line in a bulleted list, or
around text to indicate emphasis.
Formatting buttons in the compose box make it easy to format your message. For
those who prefer to type the formatting they need, this page provides an
overview of all the formatting available in Zulip. There is a convenient
message formatting reference in the Zulip
app that you can use whenever you need a reminder of the formatting syntax
below.
Text emphasis
In Zulip, you can make text bold or italic, or cross it out with strikethrough.
What you type
**bold**, *italic*, and ~~strikethrough~~ text
***~~All three at once~~***

Mention a user or group
You can mention a team member or user group to call their
attention to a message. Mentions follow the same notification
settings as direct messages and alert
words. A silent mention
allows you to refer to a user without triggering a notification. A wildcard
mention allows you to
mention everyone on a channel,
or mention all topic participants.
What you type
Users: @**Bo Lin** or @**Ariella Drake|26** (two `*`)
User group: @*support team* (one `*`)
Silent mention: @_**Bo Lin** or @_**Ariella Drake|26** (`@_` instead of `@`)
Wildcard mentions: @**all**, @**everyone**, @**channel**, @**topic** (two `*`)
A | followed by a user ID is inserted automatically when you select a
user from the typeahead suggestions, if there are two users with the same
name in the organization.

Global times
When collaborating with people in different time zones, you often need to
express a specific time clearly. In Zulip, rather than typing out your time
zone and having everyone translate the time in their heads, you can insert
a time, and it will be displayed to each user in their own time zone (just
like timestamps on Zulip messages).
What you type
A date picker will appear once you type <time.
Our next meeting is scheduled for <time:2024-08-06T17:00:00+01:00>.
You can also use other formats such as UNIX timestamps or human readable
dates, for example, <time:August 06 2024, 5:00 PM BST>.

A person in San Francisco will see:
While someone in London will see:
You can also use the Add global time

non-empty.
