macOS iTerm2 + Oh My Zsh
iTerm2
比mac下原生terminal更好用的终端，一试便知
iTerm2启用bash快捷键Alt+f,Alt+b
方法一:
profiles->keys中，将“Left option key acts as”修改为“+Esc”即可
方法二:
Preferences---Keys---新增两个键绑定后即可像在linux下一样使用Alt+f,b在命令行上以单词为单位进行移动，实测有效
Option+f ---> Send Escape Sequence ---> f
Option+b ---> Send Escape Sequence ---> b
Option+d ---> Send Escape Sequence ---> d
Option+u ---> Send Escape Sequence ---> u
