Start in the agents view and locate the displayed keybind text shown in the report. Verify the shortcut behavior, then correct the text so it matches the action it describes; done means the agents view no longer tells users that Ctrl+C stops the session when it closes the view, and the existing quit shortcut remains accurately documented.
