Keyboard Key Values (Keycode, ASCII Codes)
Keyboard key values, including keycode and ASCII code, are essential for capturing and interpreting user input from keyboards. Keycode represents a numeric identifier assigned to each key, enabling developers to differentiate between different keys. ASCII code, on the other hand, provides a numerical representation for characters, facilitating the conversion of keycodes into their corresponding characters. These key values play a vital role in capturing user input, implementing keyboard shortcuts, validating input, and simulating keyboard events in interactive applications. By understanding and utilizing keycodes and ASCII codes, developers can create applications that respond accurately to user keyboard interactions, enhancing the overall user experience.
