Common errors and how to fix them

A browser shortcut ran instead- Some keys, like Ctrl+W, are reserved by the browser and never reach the page.

Keycode Info FAQ
Use event.key for the character typed (it follows the keyboard layout) and event.code for the physical key position (good for games). keyCode is deprecated but still shown for older code.
On a French AZERTY keyboard, the key left of Z gives event.key "a" but event.code "KeyQ" — code is the position on a US layout, key is the actual character.
Which copy of a key was pressed: 0 standard, 1 left (left Shift), 2 right, 3 numpad.
Its values were never standardised across browsers and layouts. event.key and event.code replace it, but keyCode still works for compatibility.
Enter is 13, Escape is 27 and Space is 32. The arrow keys are 37–40.
No. Everything runs in your browser, so your key presses never leaves your device.
