我是程序员，我经常从百度复制粘贴代码到自己项目代码里面。mac下面，借助karabiner软件，我们可以重新映射鼠标按键。如果你不改映射，那么默认的鼠标按键4,5，是前进和后退。但是你改完了之后，它就是CTRL+C和CTRL+V了。

先安装软件，这个简单，然后重启，完成基础的授权，在系统设置，安全里面，允许监控输入。然后导入官方复杂设置中 #mouse_button 的案例。导入完了，启用其中一个，然后你修改配置文件~/.config/karabiner/karabiner.json

我把   "pointing_button": "button4" 修改为： "key_code": "v",   "modifiers": "left_command"

把 "pointing_button": "button5" 修改为： "key_code": "c",   "modifiers": "left_command"

不同的鼠标可能配置需要调整。

如果下面的配置不灵，你可能需要改一下 left_command, 换成left_control
