Quick Look is a quick preview feature developed by Apple Inc. which was introduced in their operating system, Mac OS X v10.5 "Leopard". It was announced and demonstrated at Apple's Worldwide Developers Conference 2007.
While OS X's Finder has always had icon previews, Quick Look allows users to look at the contents of a file in the Finder at full or near-full size, depending on the size of the document relative to the desktop. It can view files including, but not limited to: PDFs, HTML, QuickTime readable media, plain text and RTF text documents, Apple Keynote, Pages and Numbers, ODF documents, Microsoft Word, Excel, and PowerPoint files (including OOXML), RAW camera images.
Quick Look can also be opened in full screen and launched from the command line. Additionally, multi-page documents like PowerPoint slide shows can be navigated using the arrow keys.
