Vim is the most popular and extremely powerful text editor. It possesses a lot of features that you would not expect to have in a text editor. Most of these features make it much easier for you to do a lot of work in a little time. The Vim editor is a modal text editor; it uses modes for different purposes like inserting text, running commands, and selecting text. Modes basically decide whether pressing any key on the keyboard will insert those characters or move the cursor through the document. Therefore, it is important to know what each mode is and how to change the modes.This article will describe what Vim modes are and how to change them. Vim is a free and open-source text editor that comes installed by default with most of the operating systems.
Please note that all the commands and processes discussed in this article have been tested on the Ubuntu 20.04 LTS (Focal Fossa).
Vim Modes
In Vim, there are three modes of operation: Normal, Insert, and Visual.
Vim Enter Edit Mode
Normal mode
Normal mode is the initial mode of the Vim editor. When you open a new file edit an existing one, it starts in normal mode by default. In normal mode, you cannot insert any character. Normal mode is also known as command mode because all the keystrokes you perform are interpreted as commands. For instance, if you press k, it will move the cursor position up one line instead of inserting the character “k”. Similarly, if you press yy, it will copy the current line instead of inserting “yy”. Also, in normal mode, the uppercase and lowercase letters are treated differently. For instance, pressing o create a new line for the text below the current cursor location, while pressing O creates a new line for text above the current cursor location
To access normal mode from other modes, press Esc key.
Insert mode
Insert mode is where you can insert your text in the file. This mode inserts every character you type at the current cursor location.
Visual mode
Visual mode allows you to select text so that you may perform certain operations (cut, copy, delete) on it.
Changing the modes
As already discussed, when you create or open a file in vim, it first opens in Normal mode.
In order to type any character, you will need to switch to the Insert mode. There are different commands to enter into Insert mode from Normal mode that are i, I, o, O, a, and A. The most commonly used command to enter in to insert mode is “i”. To shift back to normal mode, press Esc.
To switch to the visual mode from Normal mode, different commands are v, V, Shift + v, and Ctrl + v. The most commonly used command to enter in to insert mode is “v”.
To switch to the visual mode from Insert mode, first shift to Normal mode by pressing the Esc, then press v to get into the Visual mode.

The text editor should be optimized for editing, not just writing, and Vim is one of them. It has separate modes for editing, inserting, and selecting text.
