上回这期视频发布以后

有的小伙伴说

让我说说这个 command + D 快捷键

在windows里应该是ctrl + D

那说实话

这个快捷键之前我还真不知道

试了以后我发现他是真香啊

什么意思呢就是

比如说我们现在想把这个css转成一行

我们就可以先选中这么一个换行

然后呢按 command + D

每按一次他就会替我查找下一个

然后呢替我们选中大家看

好到这以后呢按一下删除

加空格这样就可以了

反过来也一样

我们可以选中这个分号

这样把中间的所有的分号都给它选中

然后呢我们再按一个分号回撤

这样就行了

再比如呢大概我这有几个js变量声明

我现在想把它转成1行

然后用逗号隔开也一样

选中Command + D

然后逗号

这样就行了
