Otherwise, the value must be empty + * string or known code value defined by "UI Events + * KeyboardEvent code Values". You can check our + * current support values in + * dom/events/PhysicalKeyCodeNameList.h. + * If |keyCode| is omitted or 0, this guesses + * proper keyCode value in US-English keyboard. + * If |location| is omitted or 0, this assumes + * that left modifier key is pressed if aKeyValue + * is one of such modifier keys. + * |key|, |isComposing|, |charCode| and |which| + * are always ignored. + * Modifier states like |shiftKey|, |altKey|, + * |modifierAltGraph|, |modifierCapsLock| and + * |modifierNumLock| are not adjusted for + * aKeyValue.
