In the context of multimedia, an (technically known as Cues ) is a metadata structure within a Matroska (.mkv) file that allows media players to seek instantly to specific timestamps. Without a functional index, a player might have to scan the entire file linearly to find a specific scene, leading to slow "scrubbing" or an inability to fast-forward.
