Emmet(formerly Zen coding) is a set of plug-ins for text editors that allow for high-speed coding and editing in HTML, XML, XSLT and other structured code formats via content assist.

It uses a specific syntax in order to expand small snippets of code, similar to CSS selectors, into full-fledged HTML code and it also includes wrapping a section of code with expanded code.

The HTML pair matcher allows the user to locate the matching open/close tag for the tag at the current cursor position.

Unlike other HTML pair matchers, Emmet searches from the cursor's current position rather than scanning the document from the begining.
