Keyboard codes for Javascript

Use this reference to look up modern key codes, understand the subtle differences between numpad, function, and navigation keys, and experiment instantly with the tester beside the table.

Comprehensive key atlas

Every key below maps to the number that JavaScript reports via event.keyCode and event.which. The list covers navigation, alphanumerics, numpad keys, modifiers, and the printable symbols you hit most often.

  • Shift, Control, Alt, and the Windows keys are normalized to the same labels browsers emit.
  • Function keys and numpad shortcuts keep their dedicated slots for easier shortcut wiring.
  • Use the tester to verify codes in your current browser before wiring automation or hotkeys.
