Use Cases

Technical Background

Each keyboard key has a unique key code. In web development, the KeyboardEvent object's key property returns the text value, while code returns the physical key identifier. Modern browsers recommend using key and code instead of the deprecated keyCode. Modifier keys (Ctrl, Shift, Alt, Meta) are detected through the event's corresponding properties.
