Spell Checking Comments
======
I’m notorious for all the typos I make. Thankfully Emacs features an awesome built-in mode named `flyspell` to help poor typists like me. Flyspell highlights misspelled words as you type (a.k.a. on the fly) and has useful keybindings to quickly fix them.

Most people typically enable `flyspell` only for major modes derived from `text-mode` (e.g. `markdown-mode`, `adoc-mode`), but it can really help programmers as well by pointing out typos they make in comments. All you need to do is enable `flyspell-prog-mode`. I typically enable it for all programming modes like this:

```
(add-hook 'prog-mode-hook #'flyspell-prog-mode)
```

Now you’ll get instant feedback when you make some typo in a comment. To fix a word just press `C-c $` (`M-x flyspell-correct-word-before-point`), while your cursor is behind it.

That’s all I have for you today! Keep fixing those nasty typos!
