FAQ
Which value should my code use?
Use event.key for the character or key name, which follows the keyboard layout, and event.code for the physical key position, for example for WASD controls. keyCode and which are deprecated and shown only to help with older code.
Why do I see Process, Unidentified or keyCode 229?
During IME composition and with many on-screen mobile keyboards the browser reports key as Process or Unidentified and keyCode 229, so the actual key is unknown. Shortcuts that the browser or operating system handles first, such as Ctrl+W, may never reach the page.
