How do keycodes look?

Keycodes are typically represented as numerical values that correspond to specific keys on a keyboard. For example, the keycode for the "A" key might be represented as 65, while the "Enter" key could be 13. In programming contexts, keycodes can also be displayed in hexadecimal format, such as "0x41" for "A". These codes are used in various applications to detect and respond to keypress events.
