Setup, push to talk, and the details that matter

Use the table for a quick answer, then check the relevant setup below before relying on a shortcut during a call.

01 · Zoom

The Zoom mute shortcut

Use Alt + A on Windows or Linux and Command + Shift + A on Mac in a Zoom desktop meeting. Zoom Phone has separate call shortcuts; use the meeting keys for meetings. The web app lists enabled spacebar temporary unmute, not these desktop toggle keys.

In desktop Settings → Keyboard shortcuts, inspect or change an assignment. On Windows and Mac, supported shortcuts can be made global using the checkbox beside them. Confirm that option for the action you want to use while another app is active. Zoom keyboard settings.

For push to talk, enable the spacebar temporary-unmute option in Settings → Audio. Start muted, bring the Zoom meeting window into focus, and hold Space while speaking. Host restrictions still apply. Zoom push-to-talk setup.

02 · Microsoft Teams

How to mute on Teams

Press Ctrl + Shift + M on Windows or Command + Shift + M on Mac. Microsoft documents these toggle shortcuts for both desktop and web. In the desktop app, open the shortcut list with Ctrl + . or Command + . to review your assignments. Teams keyboard shortcuts.

For a short reply, turn on Settings → Privacy → Keyboard shortcut to unmute. While muted, hold Ctrl + Space on Windows or Option + Space on Mac, then release to mute again.

Teams warns that shortcuts can fail inside the chat box or when PowerPoint Live or Whiteboard occupies the meeting stage. Move focus back to the meeting controls and confirm your mic state. Teams temporary-unmute guidance.

03 · Google Meet

The Google Meet mute shortcut

With your Meet meeting page active, use Ctrl + D on Windows or ChromeOS, or Command + D on Mac. Outside the meeting page, your browser can handle that combination differently. Meet keyboard controls.

Turn on Push to talk in Meet's Audio settings to hold Space for a temporary reply. It is off by default. Release Space to return to mute.

Google notes that some Windows screen-reader setups give Space another function. If that affects you, use the toggle shortcut or microphone control instead. Meet accessibility and push-to-talk guidance.

04 · Discord

Discord mute and push to talk

On desktop or in the browser, the default mute toggle is Ctrl + Shift + M on Windows or Command + Shift + M on Mac. Custom keybinds are desktop-only. Deafen is a different action: it also stops the audio you hear. Discord shortcut guide.

  1. Open User Settings → Voice & Video.
  2. Under Input Mode, select Push to Talk.
  3. Use Edit Keybind to record the key you want to hold. There is no single universal PTT key to memorize.

Browser PTT only works with the window in focus. Use the desktop app for system-wide PTT. The release-delay slider changes how long audio continues after you let go. Discord voice input setup.

05 · Webex

The Webex mute shortcut

For Webex Meetings desktop, press Ctrl + M on Windows or Command + Shift + M on Mac. The host may restrict whether participants can unmute. Webex meeting mute controls.

To hold Space for a reply, first select Unmute temporarily by holding Spacebar in Audio settings. Release it when you finish speaking. Webex Meetings audio settings.

06 · Slack huddles

How to mute a Slack huddle

During a huddle, use Ctrl + Shift + Space on Windows or Linux, or Command + Shift + Space on Mac. This is a toggle: press again to unmute. Slack does not currently offer custom keyboard shortcuts. Slack keyboard controls.

Huddles work in the desktop apps, Chrome on Mac/Windows/Linux, and Firefox on Mac/Windows. Keep Slack active when checking the shortcut. Muting a channel's notifications is separate from muting your huddle microphone. Slack huddle platform guidance.

The official shortcut guide does not list a desktop hold-to-talk key. The mobile huddle menu includes a push-to-talk option, which is separate from the desktop keyboard toggle above. Do not assume holding Space in desktop Slack gives you push to talk.

When a shortcut does nothing

Check the context before changing the keys

  1. Focus the meeting. Switch to its window or browser tab. Move out of a chat box or shared content, then try again.
  2. Check your saved assignment. An edited keybind or a different app edition can change the default. Use the app's own shortcut list as the final reference.
  3. Check temporary-unmute settings. Push to talk often needs to be enabled separately. Start muted and watch the microphone icon while holding and releasing the keys.
  4. Separate a mute problem from a microphone problem. If the app shows you as unmuted but no one hears you, check the selected input, browser or system microphone permissions, and any physical mute switch.

Our microphone test and recorder can help check whether this browser receives audio from your mic. Your meeting app still needs its own input and permissions checked.

Mute shortcut questions

Is there one mute shortcut that works in every app?

No. Zoom, Meet, Teams, and Slack use different defaults. Some desktop apps offer global shortcuts, but that setting belongs to the app. Check which application and microphone a control actually affects.

What is the difference between toggle mute and push to talk?

Toggle mute changes state each time you press the shortcut. Push to talk transmits while you hold a key and returns to mute when you release it, sometimes after a configured delay. Enable the feature and verify the behavior before a meeting.

Why does the shortcut work only when the meeting is open?

Many shortcuts are handled by the active window or browser tab. Some desktop apps let you enable a global assignment; browser shortcuts generally depend on focus. Zoom's temporary spacebar unmute and Discord's browser PTT explicitly require focus. See each app's setup above.

Can I use a keyboard shortcut if the host has muted me?

A shortcut does not bypass meeting permissions. If your meeting blocks participants from unmuting, use its raise-hand or chat controls to ask the host for permission to speak.

Does this guide control my microphone?

No. This page is a reference and does not request microphone access or send keys to another app. The optional Copy button copies the displayed reference to your clipboard.

A button within reach

Prefer a physical mute button?

If you move between meeting apps all day, a dedicated control can make mute easier to find. Explore how MuteMe works with its companion app and review the setup for your computer.
