Vim and Neovim

08. 11. 2025 Updated: 27. 03. 2026 1 min read intermediate

Vim is available on every Linux system and significantly speeds up your workflow once learned. Unlike regular editors where you navigate with a mouse and type, Vim separates navigation from editing. This modal editing philosophy allows performing complex operations with just a few keystrokes — delete an entire function, rename a variable, or reformat a paragraph without touching the mouse. The initial learning curve is steep, but the return on investment comes within weeks.

Modes

  • Normal — navigation and commands (default mode)
  • Insert (i, a, o) — typing text
  • Visual (v, V, Ctrl+v) — text selection (character, line, block)
  • Command (:) — Ex commands, search, replace
h j k l, w/b, gg/G, /pattern, *
dd yy p, ciw, ci", ., 5dd
:%s/old/new/g, :w, :q

The key concept is composition: operator + motion. For example, d (delete) + w (word) deletes a word, c (change) + i" (inner quotes) changes the content inside quotes. The dot . repeats the last command — extremely powerful for repetitive edits. Macros (qa to record, @a to replay) automate more complex sequences.

Neovim

-- ~/.config/nvim/init.lua
vim.opt.number = true
vim.opt.relativenumber = true
vim.opt.tabstop = 4
vim.opt.expandtab = true
vim.g.mapleader = ' '

Neovim brings Lua configuration, a built-in LSP client for language support (autocomplete, go-to-definition, refactoring), tree-sitter for precise syntax highlighting, and an active plugin ecosystem. With plugins like telescope.nvim (fuzzy finder), nvim-lspconfig (LSP), and nvim-treesitter, Neovim becomes a full-featured IDE.

Vim Is an Investment

Start with vimtutor, learn 20 basic shortcuts, and gradually add more. After a month of daily use, you will edit faster than in any GUI editor.
