The main scientific outputs from the Tore Supra ergodic divertor experiments are recalled as well as their theoretical framework. Major references are given for further consideration and in-depth information. The surprising results, such as density pump-out or unaffected electron core temperature, are reported. These have also been observed in the recent edge-localized mode (ELM) control experiments. The understanding of their physics, stemming from experimental and theoretical work, is recalled, although further assessments are still required; this can provide an interesting starting point for the ongoing effort in the ITER framework of the control of ELMs and plasma-wall interaction.
