In Notepad++ for example when your cursor is next to a brace it will highlight the corresponding opening or closing brace on screen. Check out the link below for a example as to what I mean. http://www.atmel.com/webdoc/visualassist/visualassist._match.html How can Visual Studio do this?

The Visual Studio 2013 C# editor has brace highlighting. Place the cursor on the outside of the brace, (not the inside) to see the highlight. <img src="https://i.stack.imgur.com/qBQJe.png" alt="Default Brace color"> The default color is very subtle, use the Tools\Options\Fonts And Colors setting to apply a different highlight color. <img src="https://i.stack.imgur.com/JjVYy.png" alt="Fonts and Colors setting"> <img src="https://i.stack.imgur.com/HdQVG.png" alt="New Brace Color">
