Notepad++ is the editor that programmers most widely use because it is fast, lightweight, and filled with tons of useful features and plugins. Recently, Notepad++ added a built-in plugin for automatic spell checking. Unfortunately, this new feature can be annoying to some as it shows a red mark under most programming language keywords, under some words related specifically to the web, and under html tags. Here is how to turn it off.
