Mattermost Keyboard Shortcuts
Mattermost's shortcut set closely mirrors Slack's — Ctrl/Cmd+K for the channel quick switcher, similar message-editing conventions — which is a deliberate design choice rather than coincidence, since a large share of Mattermost's adoption comes from organizations migrating away from Slack specifically for self-hosting or data-sovereignty reasons, and matching familiar shortcuts smooths that transition considerably. Where Mattermost meaningfully diverges is in the areas tied to its self-hosted, more IT-administrator-oriented positioning: system console shortcuts and administrative navigation get more dedicated attention than they would in a purely cloud-managed SaaS tool, reflecting how much more hands-on Mattermost's typical deployment and maintenance model is compared to Slack's fully managed service. Message formatting and thread-reply shortcuts otherwise follow Slack-like Markdown-adjacent conventions closely enough that muscle memory transfers with minimal relearning for the core day-to-day messaging experience. IT and security teams in government, healthcare, and finance are disproportionately represented among Mattermost's enterprise customers specifically because those sectors face regulatory requirements around data residency and retention that a fully cloud-hosted SaaS tool can't always satisfy, making the self-hosting capability the actual deciding factor in adoption far more often than any specific feature or shortcut difference relative to Slack.
Navigation
| Action | Windows | Mac | Description |
|---|---|---|---|
| Open channel switcher | Ctrl+K | Cmd+K | Opens a searchable list of channels and direct messages to jump to by typing a few letters, directly mirroring Slack's Quick Switcher shortcut and interaction pattern. |
| Jump to next unread channel | Alt+Shift+Down | Cmd+Shift+Down | Skips ahead to the next channel or direct message carrying an unread badge, letting you clear a notification backlog top to bottom without scanning the sidebar manually for bold text — Slack uses the identical convention for the same action. |
| Search messages | Ctrl+Shift+F | Cmd+Shift+F | Opens the message search interface to find content across channels by keyword, sender, or date, supporting search modifiers similar to Slack's own search syntax. |
Messaging
| Action | Windows | Mac | Description |
|---|---|---|---|
| Edit your last message | Up Arrow (in empty message box) | Up Arrow | Pulls your last post back into an editable composer state as soon as Up Arrow is pressed on an empty message field, skipping the need to hover the message and click the small edit pencil icon that appears on mouseover. |
| Bold selected text | Ctrl+B | Cmd+B | Wraps selected text in Markdown-style asterisks to render it bold, following conventions broadly shared across most team messaging apps. |
| Reply in thread | Shift+R (with message focused, varies) | — | Brings up the thread reply panel attached to whatever message currently has keyboard focus, replying inline instead of hunting for the small reply-in-thread link with the mouse. |
| Mark current channel as read | Shift+Esc (varies) | Shift+Esc | Marks all messages in the currently open channel as read, clearing its unread indicator without needing to scroll through every message individually. |
| Open emoji picker | Ctrl+Shift+E (varies) | Cmd+Shift+E | Opens the emoji picker for inserting an emoji into the message compose box, matching a similar convention found in Slack. |
Administration
| Action | Windows | Mac | Description |
|---|---|---|---|
| Open System Console | Main menu > System Console (no dedicated key) | — | Opens Mattermost's administrative console for managing users, teams, and server configuration, reflecting the more hands-on, self-hosted administrative surface that Mattermost exposes compared to a purely cloud-managed SaaS chat tool. |
| Open account settings | Main menu > Account Settings (no dedicated key) | — | Opens personal account settings including notification preferences and display options, distinct from the System Console's server-wide administrative settings. |
Frequently Asked Questions
Why do Mattermost's shortcuts feel so similar to Slack's?
A significant portion of Mattermost's user base migrated from Slack specifically for self-hosting and data-control reasons rather than dissatisfaction with Slack's interaction design, so keeping the shortcut layout close to what Slack users already know was a deliberate retention decision, not an accident — the same logic that keeps VSCodium's keymap close to VS Code's.
What does 'self-hosted' actually mean for a day-to-day Mattermost user versus using Slack?
Self-hosting means an organization runs Mattermost's server software on its own infrastructure (or a private cloud instance) rather than relying on Mattermost's own managed cloud servers, giving the organization direct control over data storage location and retention — for an individual end user, the day-to-day messaging experience is largely similar regardless of hosting model, though administrative capabilities and available integrations can differ by deployment.
Is Mattermost really free, or does self-hosting still involve costs?
The core Mattermost software is open-source and free to self-host, though running it still requires your own server infrastructure and IT maintenance effort, which is itself a real cost even without a licensing fee; Mattermost also offers paid Enterprise tiers with additional features and support for organizations that want them.
Can Mattermost integrate with third-party tools the way Slack does with its App Directory?
Yes — Mattermost supports incoming/outgoing webhooks, slash commands, and a plugin marketplace for integrating with external tools, though because Mattermost is more commonly self-hosted, setting up certain integrations can require more hands-on server configuration than a purely cloud-hosted SaaS tool's typically simpler one-click app installation flow.
Does the System Console require a completely different login than regular messaging?
No — System Console access is granted based on the permissions of your regular Mattermost account (typically an admin role) rather than a separate login system, so an authorized user simply navigates to the console through the main menu using their existing session rather than authenticating separately.
Does Mattermost support voice and video calls natively, or does it require a separate plugin?
Native voice and video calling capability has been added as a built-in feature in more recent Mattermost versions, though some deployments still rely on a separate integrated plugin (like a Jitsi or Zoom integration) depending on which version and configuration a particular organization has deployed.
Can I use the same keyboard shortcuts across the desktop app, mobile app, and web browser version of Mattermost?
the mobile apps trade the keyboard-driven quick switcher and shortcut set for a simpler tap-based channel list and swipe gestures suited to a phone screen, meaning a Mattermost admin who's fully fluent in the desktop shortcuts covered here will still need to fall back on touch navigation once they're checking messages from a phone.
Can Mattermost administrators enforce specific keyboard shortcut behavior across an organization?
No — keyboard shortcuts are a per-user client-side preference rather than something a System Console administrator can centrally enforce or restrict across an organization's users, unlike some server-side settings such as message retention policies.
Are Mattermost keyboard shortcuts customizable per user?
Limited customization exists through browser-level extensions or OS remapping tools since Mattermost itself does not expose an in-app keymap editor comparable to a code editor, meaning most users work with the fixed default set covered here rather than a personalized layout.
Can I open a channel directly by typing its name instead of scrolling the sidebar to find it?
Yes — Ctrl+K (or Cmd+K on Mac) brings up Mattermost's Quick Switcher, the same binding Slack uses for its equivalent jump-to-channel feature, and typing a partial name filters the list of channels, teams, and direct messages in real time so you rarely need to type more than a few characters before the one you want is highlighted at the top.
