倒腾vim时候的cheatsheet，vim模式可以使双手脱离鼠标，还是很便捷的，虽然有一丢丢学习成本，但还是很值得的。

Why Vim

Just because your workflow will be interrupted frequently when navigating your cursor is needed. But you can navigate easily with Vim compared with other text editor. Though it will take some time to get used to Vim, but in the long run, it's definitely worth it.

Here is quick reference of the most commonly used vim command, hope it will help. So let's get started!

Mode matters!

  • append, a or A to append after current position or end
  • open, o or O to open a new line below or above
