Hi Uomo,
This feature is still available. When in the PlanetPress Talk Editor, press CTRL SHIFT / (control-shift-forward_slash) to comment all selected lines and CTRL SHIFT . (control-shift-period) to uncomment them.
Even though those shortcuts don't show up as menu options in the Editor, they are documented in the PlanetPress Design Reference guide.
