Vim’s three distinctive modes
Because I recently realized how efficient and powerful Vim is as a text editing tool, I can even edit text at the speed of thinking. However, because there are too many details, I opened a column to help myself record and learn Vim.
In addition, let’s briefly introduce the difference between vi and vim. VIM is an upgraded version of vi. In addition to being compatible with all instructions of vi, VIM also has some new features (multi-level undo, ease of use , syntax highlighting, visual operations, etc.)
If you want to use VIM under win system, you can refer to Windows 11 Installation Vim Editor Configuration Guide
