I. Introduction of VIM Mode

1. Concept: The following introductory content from the Wikipedia vim

There are many modes of vim from VI, this unique design is easy to confuse the beginner. Almost all editors have two modes of inserting and executing commands, and most editors use a different approach to vim: the command directory (mouse or keyboard driver), the combination of keys (usually with the control key (CTRL) and the ALT key (ALT)) or the mouse input. Vim and VI, just as the keyboard to switch among these modes. This allows vim to operate without a menu or mouse, and to minimize the operation of key combinations. It can greatly enhance the speed and efficiency of the text entry clerk or programmer.

VIM has 6 basic modes and 5 derivation modes, and here we simply introduce the next 6 basic modes:

• Normal mode

• Insertion modes (insert mode)

• Visual modes (visual mode)

• Selection mode (select modes)

• Command line mode

• Ex modes (ex mode)

2. Switching of three common modes

Vim starts into normal mode, in insert mode or command line mode, just press Esc or Ctrl+[ (this is no use in the VIM course environment) to enter normal mode. In normal mode i , press (insert) or a (attach) keys to enter the insert mode, in normal mode press : enter command line mode. In the command line mode, enter the wq carriage return and save and exit Vim.

3. Enter the VIM1. Use the VIM command to enter the Vim interface

Vim is appended with the file name that you want to open, or that does not exist (then as a new file). Open the Xfce terminal and enter the following command

2. Cursor movement
