Triangle, Arrow
This is a "previous song" button, which consists of two triangles pointing to the left at the same time, and a vertical rectangle on the left. On the other hand, OpenMoji platform replaces two triangles with two broken lines and rectangles with a vertical line, which is different from other platform icons in appearance. It should be noted that the background color of icons will be different on different platforms. Except that OpenMoji platform does not display background frames, Google and Facebook platform display orange and gray background frames respectively, other platforms display blue frames with different shades. As for the color of symbols, except for LG platform, which uses black, other platforms basically use white, and emojidex platform also outlines orange and blue borders in addition to white symbols.
This emoji is usually used to refer to the meaning of returning to the previous song when listening to music, or going to the previous chapter when browsing web pages.
