It’s been around for quite some time but I didn’t discover this until today, heuristically. From the Slack documentation:1

  • With two fingers to the left for the previous channel or conversation, and with two fingers to the right for the next channel or conversation.
  • With three finger [sic] to the left for the previous team, and three fingers to the right for the next team.

Slack is amazing. One of my favorite applications of all time.
