title: "Manage your @mention and keyword notifications"
---
You're [notified](/end-user-guide/preferences/manage-your-notifications) in a [web browser](/end-user-guide/preferences/manage-your-web-notifications), the [desktop app](/end-user-guide/preferences/manage-your-desktop-notifications), and on your [mobile device](/end-user-guide/preferences/manage-your-mobile-notifications), when you're @mentioned by your username or first name, @mentioned as part of a user group, and for matches to keywords you're following.
You're also notified when someone uses channel-wide [@mentions](/end-user-guide/collaborate/mention-people) including [@channel and @all](/end-user-guide/collaborate/mention-people#channel-and-all), as well as [@here](/end-user-guide/collaborate/mention-people#here).
For all other messages, channels appear bolded to indicate unread activity.
## Customize notification keywords
Using a web browser or the desktop app, you can customize keywords to trigger notifications. Keywords aren't case-sensitive.
For example, you can receive notifications for all messages and threads related to a specific topic, project name, or customer.
Separate multiple keywords using commas or by pressing Tab, and use Backspace to manage keywords.
## Passively track keywords (no notification)
From Mattermost v9.3, Mattermost Enterprise and Professional customers interested calling attention to specific topics of interest across channels can do so without sending notifications to a Mattermost client.
Using a web browser or the desktop app, you can passively track key terms by specifying single or multiple words to be highlighted in all channels you're a member of. Keywords and phrases are automatically highlighted using a color based on your [Mattermost theme](/end-user-guide/preferences/customize-your-theme).
