What is Key Code Finder?
When programming keyboard shortcuts or web interactions you need to know exactly what values JavaScript reports for each key. This tool shows you the event properties in real time: event.key, event.code, the legacy keyCode and the active modifiers (Ctrl, Shift, Alt, Meta).
Just press a key and see its values instantly, without opening the console. It's the fastest way to find out what to compare in a keydown handler, especially with special keys whose code isn't obvious.
