Common Vim/Vi operations (version 2)

Colleagues around you are either using vim or Emacs. If you use ultraedit, you are embarrassed to say hello to others. What plug-ins are there? syntax highlighting and spelling check, everything that can be opened to it is a word: Cool.

If you say so, you have to learn how to do it for half a year. Half a year! It's far from getting started. It's good to learn to move the cursor. You don't have to worry about it, it's just moving around !!!
