A conference always runs in a browser tab of its own, so the call gets the whole window and the chat stays the chat. While it is over there the chat says so along the bottom of its window — a readout and not a door, because the card in the conversation is the way in, and there is no Leave beside it either: you leave a call from the screen that is in it. Ctrl+Shift with the arrow keys works inside that tab: Up for the microphone, Left for the camera, Right for the layout, Down to move the focus; Ctrl+Shift+Q leaves. Closing the tab is not leaving either: the room keeps you for the reconnection window, and reopening the address puts you straight back in. Only Leave, which asks first, actually ends your part in the call — and being removed from the channel ends it for you. The call controls — microphone, camera, screen share, raised hand, reactions and the Leave button — are in a dark bar at the bottom of the video. The bar fades shortly after the pointer leaves the video, and it comes back when you point at the video or press Tab. On a touch screen it is always visible. In the automatic layout, when there is exactly one other video in the call, it fills the stage and your own camera moves to a corner. When you are alone, your camera fills the stage until someone joins. Push-to-talk: while your microphone is off, hold Ctrl+Shift+Z to talk, and it goes quiet again as soon as you let go. If the tab loses the server, the status at the top says Reconnecting to the server… and the call controls wait until it is back.
A conference always runs in a browser tab of its own — the chat has no window for one. The card posted in the channel is the door, and the only one: Group Call in the conversation's toolbar opens the room and writes that card rather than going anywhere itself. The call gets the whole window and the conversation stays where it was.
Closing the tab is not leaving
The room decides who is in the call, not the tab. Closing the call's tab starts the reconnection window rather than ending your part, and opening the same address again puts you back where you were. Closing the chat's tab does not drop you out of the channel either, as long as the call is still open — you leave the channels when the last of your windows closes. Only Leave, which asks first, is final. The tab always shows a way back to the chat along its bottom edge: there is no conversation inside a call.
