1. What is Vim?

Vim is VI improved, an enhanced version of the editor VI. It is extremely powerful and complies with SE (software)
Engineer, Software Engineer) used editor. If you are a professional se, you must be looking for an excellent editor that can be customized and flexibly edited. The answer is vim or Emacs. This continuous blog will introduce you to the vim editor. As for another powerful editor Emacs, we will see it in a series of blog posts in the future.

2. Where is the configuration file?

If you are using Windows, the configuration file is the vimrc file under your vim installation directory.

If you are using a Linux system and installed with APT-Get by default, your configuration file is/usr/share/Vim/vimrc.

If you are using Mac OS X, the configuration file is/usr/share/Vim/vimrc.

3. What does RC in vimrc mean?

Why is this meaningless question also listed? The reason is very simple, that is, the second question I want to ask at the beginning of my exposure to VIM is this (the first is the above "1 "). Generally, when running a software, environment, or tool, some commands that need to be initially executed are called run
Commands, that is, RC. According to wikipedia.org, the RC abbreviation is derived from MIT's compatible time-based operating system (compatible ).
Time-sharing system, ctss) [Reference 1]. So if you see systemrc or screenrc later, you will know why.

4. Three basic modes

In "everyone learns Vim", we mentioned that Vim has 6 + 5 models. However, apart from the degree of subdivision, there are actually only three common modes: normal.
Mode, insert mode, and command-line mode.

From normal mode to insert mode, you can press I, I, a, a, O, O, R, R. I and I represent insert, R and R represent replace ).

From insert mode to normal mode, you only need to press ESC.

From normal mode to command-line mode, you can press ":", "/", and "?". ":" Indicates the vim command, "/" indicates the string to be searched down, "?" Indicates that the string to be searched up is entered later.

From command-line mode to normal mode, you only need to press ESC.

You can understand normal mode as normal. To enter any other mode, you need a special method, while returning from other special modes to normal.
Press the ESC key.

5. The most common configurations in VIM

When you try to Google the vimrc configurations of some other people, you will find an article called
