⏫ Fast Up Button
The Fast Up Button emoji is used to speed up a video or some music. Don’t confuse this with the fast forward option since this speeds up the sound instead of the image. If you enjoy listening to high pitch songs or videos, than this is the button for you.
⏹️ Stop Button
The Stop Button emoji is a solid coloured square. This button is used to completely stop all sound activities whether out of your own initiative or someone else’s. If you stop your own music, you probably either got bored of listening or wanted some quiet time.
The parking emoji was introduced in 2009 and released as part of the Unicode 11.0 standard. This emoji can be found under the symbols category.
