    # - A new terminal screen is opened (or rather the current terminal is
    #   requested into either :raw or :cooked mode).
    # - The cursor visibility is then set dependent on this mode. In :raw mode,
    #   the cursor is hidden.
    # - The `:_initialize_` event is triggered. Vedeu does not handle this
    #   event; the client application may treat this event as Vedeu signalling
    #   that it is now ready.
    # - We enter into the main sequence where the application will either run
    #   once or continuous, interactively or standalone.
