Which key is used to rewind during playback?

The J key is used to rewind during playback, which is a common feature in various media playback applications. When pressed, it triggers the playback to go backward, allowing the user to retrace their steps and listen to a previous section of audio or video. This functionality is especially useful for reviewing content, making it a crucial tool for users who may want to catch details they missed the first time around.

In many applications, each key is designated a specific function: the K key is typically used for pause or play, the L key for fast forward, and the M key often serves as a mute function. Thus, each key serves a distinct purpose, making the controls intuitive for media navigation. The assignment of the J key for rewinding aligns with the standard conventions found in various software, which helps users easily remember how to control playback effectively.
