Meaning
Two left-pointing triangles side by side, the rewind control. It means going back quickly through a video or song, and figuratively turning back time to an earlier moment.
It is a favourite for throwback posts and old memories, and for asking someone to repeat what they just said: “⏪ Wait, rewind, you met who?” Pair it with 📸 or 🕰️ for old photos, and with ⏩ when comparing then and now.
