Three modes description of Vim Editor

The VIM editor can basically be divided into 3 modes, namely command mode, insert mode (insert modes), and end line mode, which shows a diagram of how Vim's various modes convert to each other.

Command mode: Controls the movement of the screen cursor, deletes text, copies, and so on (does not use the [Del] key and [Backspace] key) and enters the insert mode, or returns to the bottom row mode.

Insert mode: You can enter text only in insert mode. Press the [ESC] key to return to command line mode. Many vim editor users want to be able to enter content as soon as they open vim, but this cannot be successful because it is in command mode when the Vim editor is just opened.

Bottom line mode: Save the file or quit Vim, but also set the editing environment and some compile work, such as listing line numbers, looking for strings, and so on.

In some books, the Vim editor is simplified into two modes, and the bottom line pattern is counted as command line mode.
