To find the keycode of any key, open the utilAZ keycode info tool and press the key you want to identify. The tool instantly displays the numeric keyCode value, the event.key string, and the event.code physical key identifier. This works for all keys including letters, numbers, function keys, arrows, and special characters.

The keycode info tool is used by web developers and game developers to identify keyboard event properties in real time. It helps when building keyboard shortcuts, handling user input in forms, creating game controls, debugging event listeners, and ensuring cross-browser compatibility of keyboard interactions.

To detect a spacebar press in JavaScript, listen for the keydown or keyup event and check if event.code equals 'Space' or event.key equals ' ' (a single space character). The legacy event.keyCode for spacebar is 32. Using event.code is recommended because it identifies the physical key regardless of keyboard layout.

event.key returns the character value produced by the key press (like 'a', 'A', or 'Enter'), which changes based on modifier keys and keyboard layout. event.code returns the physical key position on the keyboard (like 'KeyA' or 'Space'), which stays the same regardless of layout or language. Use event.key for text input and event.code for game controls or shortcuts.

You can test keyboard events online using the utilAZ keycode info tool. Simply open the page, click in the testing area, and press any key. The tool displays all event properties including keyCode, key, code, which, charCode, and modifier states (Ctrl, Alt, Shift, Meta) in real time without any installation required.
