That is why that is not useful for trapping any key alone.īut you have to take special care choosing the event to trap the cursor keys because Webkit has decided not to trap them with the keypress event as it is not in the standard. As zzzzBov explained, the HTML accesskey defines a key that will be trapped only when it is combined with the ALT key.
