A guide for Vim beginners

It can be challenging to transition from a full-fledged IDE (such as VScode, Intellij IDEA) to Vim. Vim has a steep learning curve, especially for beginners. As someone who has struggled to learn Vim multiple times, I understand the difficulties involved. That’s why I have created this guide to help you overcome the initial hurdles.

The key differences between this guide and other guides are that:

• The commands are categorized into 4 modes: Normal Mode, Insert Mode, Command-Line Mode and Visual Mode.
• It introduces the idea with Verbs and Nouns. Verbs represent that actions users take, Nouns are the text objects which Verbs act upon. Verbs consist of Transitive Verbs and Intransitive Verbs.
• Transitive Verbs are the Verbs need to work with text objects.
• Intransitive Verbs are the Verbs work alone without text objects.

Four modes

Normal Mode

It’s the default mode when you first enter Vim.
The reason why this is the default mode is because we spend most of our time reviewing and updating text rather than writing new contents.
You can’t insert text directly in this mode. This is the key difference between Vim and other text editors.

Text object

A command is able to move the cursor to a specific place in the document. Text object is the content that cursor just go through.
A text object are blocks of text which can be select and manipulate as an entity.
For example:
h will move cursor to the left, thus it also represents a text object - the char on the left, dh will delete the char on the left.
l will more the cursor to the right, dl will delete the char on the right. d2l will delete 2 chars on the right.
w means word, type w will move the cursor after the current word. dw will delete the word. d2w will delete two words.
0 means start of the line, type 0 will move the cursor to the start of the line. d0 will delete the whole content that the cursor just go through.
$ means end of the line, guess what d$ will do, and give it a try.

This is not an exclusive list of text objects, more of them will be illustrated in the image.

Transitive Verb

Transitive Verb need to work with a text object. There are 3 transitive verbs.

• c - change.
  • cw - delete a word and insert
  • cc - delete a line and insert
• d - delete.
  • dw - delete a word
  • dd - delete a line
  • d2d - delete 2 lines
• y - yank(copy), it means pull the text in to register
  • yw - copy a word
  • yy - copy a line
  • y2y - copy 2 lines

Intransitive Verb

Intransitive Verbs are the verb can work without a text object. There are many of them. Some of the most used verbs are

• p - paste
• x - kill a char
• s - kill a char and insert
• u - undo
• ctrl - r - redo
