Vim in 100 Seconds

Vim’s core pitch is simple: a keyboard-first editor can make coding faster by keeping hands on the keys and reducing context switching to the mouse. Built on the original Unix text editor vi (released in 1976), Vim arrived in 1991 with a long list of improvements—and it still runs in the terminal and on most systems. That portability matters because it means Vim often appears when you least expect it (for example, when a command drops you into an editor with no GUI). Exiting is therefore a practical survival skill: “:q” quits an unmodified file, “:q!” discards changes, and “:wq” saves and quits.

Once inside, Vim’s power comes from mode-based editing. Normal mode is for navigation and commands; insert mode is for typing; visual mode supports selection; and command-line mode handles “:” commands like setting options. Movement is fast and mnemonic-driven: “h” and “l” move left and right, while “j” and “k” move down and up. Deletion is equally direct: “x” removes a character under the cursor, and “dd” deletes an entire line. Mistakes are recoverable with “u” for undo. For readability, Vim can add line numbers via “:set number,” and line-jumping can be done with “:number.”

Copying, saving, and running code are also handled without leaving the editor. Pasting from the system clipboard uses “+p,” saving uses “:w,” and running a command from within Vim uses “:! <shell command>.” The overall workflow is designed to keep editing and execution tightly coupled—type, adjust, save, run—without reaching for a mouse.

The transcript then pivots to why Vim still matters even in the era of modern IDEs, arguing that it’s an “evergreen” skill: once learned, the muscle memory carries across a career. The practical route is learning Vim inside VS Code rather than abandoning it. Setup involves installing the “vim” extension (specifically “vscodevim.vim” with about 2 million installations mentioned) and enabling key repeat through the “VS Code Vim” GitHub repository instructions. After restarting VS Code, a quick test—holding “k” to see cursor movement—confirms key repeat is working.

With the environment ready, the focus shifts to a small command set that delivers most of the benefit quickly. Navigation uses “h j k l” in command mode. Insert-mode entry uses “i,” while line-focused insertions use “I” (beginning of line) and “A” (end of line). Lowercase “a” appends after the cursor, and “x” deletes characters without leaving command mode. Character replacement uses “r,” which swaps the character under the cursor with what’s typed next. The message is that Vim can be adopted incrementally—especially inside VS Code—by learning a handful of commands that make day-to-day editing smoother and more keyboard-native.
