Vim survival guide: the 20 keys you actually need

Tags: Linux, Terminal, Developer Tips

Introduction – what, why, and who this is for

Vim is everywhere on Linux servers, in Docker containers, and even inside many IDEs. It’s powerful, but the default learning curve feels like climbing a mountain of obscure commands. This guide cuts the noise down to 20 keys that let you navigate, edit, and save files without ever leaving the keyboard.

If you:

• are new to Vim or only use it for quick edits,
• want to feel confident after a five‑minute practice session,

then this cheat‑sheet plus a short drill will get you editing like a pro in under ten minutes.

Part 1 – The absolute essentials

These 20 keys cover movement, editing, saving, and undo/redo—the core workflow for any file.

Part 2 – Putting the keys together: a 5‑minute editing drill

1. Open a test file

   echo -e "function hello(){\n    console.log('hi');\n}\n" > demo.js
   vim demo.js
   

2. Navigate
   • Press gg to go to the top.
   • Use w to land on hello.
3. Rename the function
   • Type ciw (change inner word) → greet → <Esc>.
4. Add a missing semicolon
   • Move to the console.log line with j.
   • Jump to the end of the line with $.
   • Press i; then <Esc>.
5. Duplicate the console.log line
   • yy (yank line).
   • Move down with j.
   • p (paste).
6. Indent the new line
   • V to select the line.
   • > to indent.
7. Undo the duplication
   • Press u.
8. Save and quit
   • Type :wq and <Enter>.

You’ve just used movement (gg, w, $, j), editing (ciw, i;, yy, p, >), undo (u), and saving (:wq)—all within 5 minutes.

Hands‑on example – a runnable script that demonstrates Vim commands

Below is a tiny Bash script you can copy, run, and then edit with Vim using only the 20 keys.

#!/usr/bin/env bash
# demo_vim.sh – prints a greeting and the current date

greet() {
    echo "Hello, world!"
    echo "Today is $(date +%A), $(date +%Y-%m-%d)"
}

greet

1. Save the script as demo_vim.sh and make it executable:

chmod +x demo_vim.sh

1. Open it in Vim:

vim demo_vim.sh

Now try the drill from Part 2, but with a twist:

• Change “Hello, world!” to “Hi, Vim!” (ciw → Hi → <Esc>).
• Add a comment above the function (O → # prints a friendly message → <Esc>).
• Delete the blank line after the function (dd).
• Save (:w) and quit (:q).

Run the script again:

./demo_vim.sh

You should see the updated greeting. Every change was made with the 20 keys only.

Common mistakes / troubleshooting

Try it yourself – short exercise

1. Open a new file notes.txt with Vim.
2. Write three lines of any text.
3. Using only the 20 keys, reorder the lines so the third line becomes the first.
4. Save and quit.

Hint: Use visual line mode (V), move the selected line with :m command, or yank (yy) and paste (p).

What’s next

• Mastering motions – learn the power of f, t, ;, and , for character‑wise jumps.
• Registers and macros – record repetitive edits with q and replay with @.
• Plugins for beginners – try vim-sensible and nerdtree to make Vim more approachable.
• From Vim to Neovim – see why many developers switch and what new features to expect.
