Also, don’t expect to be more efficient with vim than any another editor in less than 3 days. In fact, it will certainly take weeks instead of 3 days. Vim editor commands are hard to learn but incredible to use.

I have designed this article in different four levels, so you won’t lose enthusiasm & step up slowly and I suggest you start slow with level 1.

Level 1Level 2Level 3Level 4

Beginner

  • Open vim editor by typing vim filename (i.e. vim main.c).
  • In a standard editor, typing on the keyboard is enough to write something and see it on the screen, but not this time. Because vim is in normal mode.
  • To switch to insert mode, you need to type the letter i. As a result, you can type letters like in a standard editor.
  • After that, to get back to normal mode just press the ESC key.
  • By above all, you know how to switch between insert and normal mode. And, here are the commands that you need in order to survive in normal mode:
