Type in several panes at once
Send what you type or paste in one pane to the other panes you select.
Turn on broadcast for the focused pane with Alt+Cmd+B on macOS or Ctrl+Alt+B on Windows and Linux, or for every pane of a tab with Alt+Cmd+I on macOS or Ctrl+Alt+I on Windows and Linux. What you type or paste into one selected pane goes to the others too. Selected panes show a Broadcast badge, and a button in the tab strip shows the count and turns it all off.
