In the realm of computer programming, scan codes are a crucial component in the communication between keyboards and computers. These codes are generated by keyboards when keys are pressed, allowing software to interpret and respond accordingly. Among the numerous scan codes, one particular code stands out for its uniqueness and functionality: Scan Code 256. Among the numerous scan codes, one particular code
