Each monitor has its own numbered workspaces: list_windows with workspace \"4\" shows workspace 4 on every monitor. Window and workspace state come straight from Umbriel's IPC socket; use run_action for any compositor action without a dedicated tool. For questions about Umbriel itself, use umbriel_info (version and state), list_actions (what it can do), config_options (valid config keys) and read_config (the user's keybinds and settings) instead of guessing. Change keybinds with set_keybind and remove_keybind rather than editing the config file directly."
