A powerful VIM editor

Haha, small series again, today, small series will introduce you to the powerful Vim editor on Linux. First of all, let us introduce what is the Vim editor. The Vim editor, also known as a text editor, does not require a graphical interface to work with Vim, but is edited by using keyboard commands, which is a favorite editor for many programmers because of its high efficiency.

Three main modes of VIM:

Command mode: The default mode, control the screen cursor movement, character, word or line deletion, cut copy text and so on.

Insert mode: Only in the insert mode, you can enter the text, press the "ESC" key to return to the command line mode.

Extended Command mode: Save or exit the file, or set the editing environment, such as setting the line number, matching the parentheses in pairs, and so on.
