验证参数是否与该键盘事件匹配。空参数将被忽略，但至少需要一个非空参数。要验证是否按下了任何控制键，请传递一个空数组：‘control_keys: []`。

def matches?(control_keys: nil, virtual_key_code: nil, char_code: nil)
  raise ArgumentError, 'No argument was passed to match key event' if control_keys.nil? && virtual_key_code.nil? && char_code.nil?

  (control_keys.nil? || [*control_keys].sort == @control_keys) &&
  (virtual_key_code.nil? || @virtual_key_code == virtual_key_code) &&
