Double arrow emojis signal direction or choice without saying a word. Use ←→ or ↔️↔️ when you're debating between two options in a text or Slack thread, or drop ↖️↘️ and ↗️↙️ in navigation guides and step-by-step instructions. When you want to highlight ups and downs in a status update, ↕️↕️ fits right in. Handy for clear back-and-forths or subtle hints at movement.
