Two triangles pointing to the left. Most commonly used as a symbol for rewinding media such as video tapes, CDs, or digital audio and video.

May be used figuratively to suggest going back in time, revisiting the past, undoing a recent action, or rapidly moving backward through events, memories, or information.

Typically depicted as a white symbol on a blue or gray square background, though Google and Samsung's designs have an orange background.

Fast Reverse Button was approved as part of Unicode 6.0 in 2010 under the name "Black Left-Pointing Double Triangle" and added to Emoji 1.0 in 2015.
