Vim is a powerful and highly customizable text editor that has gained a cult following among developers and power users. Known for its efficiency and versatility, Vim offers a wide range of features and commands that can significantly enhance your productivity.
The Vim Philosophy
Vim follows the modal editing philosophy, which means it has different modes for different tasks. The two primary modes are:
Normal Mode
This is the default mode where you can navigate, search, and issue commands.
It’s the mode you enter when you open a file in Vim.
Insert Mode
- In this mode, you can enter text as you would in any other text editor.
Modes of Vim
Normal Mode
Normal Mode is the default mode in Vim, and it’s where you spend most of your time when navigating and editing files.
In this mode, Vim provides powerful navigation and manipulation capabilities.
You can issue commands, move the cursor, search for text, delete and copy lines, and perform various editing tasks.
In Normal Mode, keystrokes are interpreted as commands rather than text input.
For example, pressing
dfollowed byd(dd) deletes the current line, andyfollowed byy(yy) copies the current line.Many commands in Normal Mode consist of single or multiple keystrokes, often combined with modifiers or operands.
To enter Normal Mode from other modes, you can press the Esc key.
Insert Mode
Insert Mode is where you can directly input and edit text as you would in any other text editor.
In this mode, Vim behaves similarly to traditional text editors.
You can insert characters, delete text, use arrow keys for navigation, and use shortcuts for common editing tasks.
To enter Insert Mode from Normal Mode, press the
ikey.Once in Insert Mode, you can type your text. Pressing Esc will return you to Normal Mode.
Visual Mode
Visual Mode allows you to select and manipulate blocks of text visually.
This mode is particularly useful for making changes to specific regions of your text, such as copying, deleting, or applying formatting.
There are three variations of Visual Mode:
Character-wise Visual Mode: Selects text character by character.
Line-wise Visual Mode: Selects entire lines of text.
Block-wise Visual Mode: Selects a rectangular block of text.
To enter Visual Mode, first enter Normal Mode, navigate to the desired starting point, and then press one of the following keys:
v: Character-wise Visual Mode.
Shift + v: Line-wise Visual Mode.
Ctrl + v: Block-wise Visual Mode.
Once in Visual Mode, you can move the cursor to select the desired text.
After selecting the text, you can perform operations like copying, deleting, or indenting the selection.
