Hot cues are specific signals or markers used in live performances, such as theater or music, to indicate when a particular action or event should occur. They help performers and crew members stay in sync, ensuring that everything runs smoothly. Hot cues can be visual, like a light change, or auditory, like a sound effect, and are crucial for timing. In the context of broadcasting, hot cues are often used in radio and television to prompt transitions between segments or to signal when to start or stop a particular action. This helps maintain the flow of the program and keeps the audience engaged.
