Before I start, just remember, when in doubt just don't close vim and you'll live.

Exiting Vim

It's easier said than done for some, there's countless articles asking for help, here's a shortcut:

Intent: Write and Quit

If you intend to write and quit (save changes, exit), you should follow this key bindings:

1. ESCAPE
2. :
3. wq
4. ENTER

Intent: Write, but don't quit

If you intend to write and don't quit, simply run:

1. ESCAPE
2. :
3. w
4. ENTER

Editing content

You can either use the i key, or hit insert to write content in vim. If you hit r or double hit insert, it will open the replace mode.

Undo, anyone?

In order to undo, make sure you're not in write mode (hit escape), and hit the U key until satisfied.

Can I redo it?

Yep, r until satisfied.

How the heck can I fix the indentation?

A little opinionated, but if you run this command then hit F7, it'll format your code in an opinionated way:

1. ESCAPE
2. :map mzgg=G`z
3. ENTER
4. [KEY:F7]

That's all for now!

This should get you by using vim in it's most basic format!
