In a voice chat on the desktop app you can bind a key to your microphone. Hold it to speak, release it to be silent, and it keeps working while you are in another window entirely.
It is the difference between a call where everyone hears your keyboard and one where they hear whoever is talking.
What you will be able to do
- check_circle Bind a push-to-talk key and use it without Telegram in focus.
- check_circle Choose a key that will not fire by accident in whatever you are doing.
- check_circle Get past the permission macOS asks for, which is where most people stop.
- check_circle Know when open microphone is the better choice.
The binding lives in the voice chat settings on the desktop client — there is no equivalent on a phone.

The point of push-to-talk is that it has to work when Telegram is not the window you are looking at. The desktop clients register the key with the operating system, so holding it opens your microphone whether you are in a browser, an editor or a game.
Releasing it closes the microphone again after a very short delay. That delay is deliberate: without it, the last syllable of every sentence would be cut off as your thumb comes up.
There is a second mode worth knowing about. Instead of holding a key to speak, you can bind one to toggle mute on and off — better for a long meeting where you talk in paragraphs rather than in bursts.
Choosing the key, and choosing the mode
Four decisions, all of which are obvious afterwards and none of which are obvious first.

The setup that works for most people: a modifier key, hold-to-talk, and the call window visible.
settings Setting it up
- Open a voice chat on the desktop app The settings are inside the call rather than in the app's main Settings.
- Open the call settings The menu in the voice chat window.
- Bind the key Choose push-to-talk, then press the key you want. It is recorded as you press it.
- Grant permission if asked macOS will prompt for Accessibility. Without it the binding is inert.
- Test it in another window Open something else, hold the key, and watch the microphone indicator in the call.
This page is one desktop-only feature. The curriculum step covers the desktop client itself: which build to install, what it does that the phone app does not, and the settings worth changing on a machine you work at.
