var 开关弹幕= 96;//小键盘数字键0，可以自己更改
var 增加速度= 107;//小键盘“+”键，可以自己更改播放速度设置在一个键上，按一下为1.25倍，按两下1.5呗，三下2倍，第四下回归正常速度
var 降低速度= 109;//小键盘“-”键
var 控制全屏 = 18//键盘“Alt”键，可以自己更改

//以上每一个按键都可以自定义，可以按照自己的喜好自行对照键盘键位对应编码来修改，下面是提供参考的键盘编码表链接

//笔记本电脑或者是没有小键盘的同学，请参考下面的键盘编码表更改键位

// 对照修改的键盘编码表链接，复制右边的链接到地址栏打开https://jingyan.baidu.com/article/fedf073780e16335ac8977a4.html
