|Description||Files with a .key extension are created by Apple's "Keynote" application which forms part of Apple's iWork office suite, a set of applications which run on the Mac OS X and iOS operating systems, and also includes Numbers (for spreadsheets) and Pages (for word processing).
Keynote began life in 2002 as an internal Apple tool developed for Steve Jobs to help him present at MacWorld. The first version was made available to the public in 2003 as Keynote 1.0 and was designed to compete with Microsoft's Powerpoint presentation software which formed part of Microsoft Office.
Designed to let users easily create, play and share presentations, Keynote contains most of the features found in modern presentation software, such as a slide navigator, the ability to add tables, shapes and charts to slides and a powerful media browser which allows users to drag and drop music from from iTunes, and photos from iPhoto and Aperture into their slides.
Keynote contains a large number of pre-designed themes to let users select common presentation formats, and powerful graphics tools to manipulate embedded images and provide advanced 3D transitions between slides (powered by OpenGL). The major Keynote releases are summarised below:

|Technical Details||Official file format specifications for iWork Keynote files are not published by Apple, but it is still possible to look at a developer document Apple released for iWork '05 file formats.
A .key file is actually a compressed ZIP file comprised of a number of other different files combined that together make up a .key file. The most recent version of Keynote saves files with an "Index" directory containing Apple's proprietary IWA file format, a "Metadata" directory with .plist files, a "Data" directory with image assets (e.g. backgrounds and photos used in slides) and one or more jpg files for allowing quick previews.
Files created by Keynote in iWork cannot be opened by programs other than iWork.

|Description||Tiff was originally created by a company called Aldus, and is now owned by Adobe systems, it is a file format for storing images, including line art and photographs. It was created due to the popularity of scanners and was thought-up to become the standard scanned image file format. It is a popular format for high-colour-depth images and it has also been adapted to accommodate greyscale images.|

|Technical Details||A TIFF file is made up of many different blocks which define the palette data or the LZW-compressed body among other things. The byte order is either Motorola or Intel depending on the first word. if it is MM, then you have Motorola byte ordering and likewise if it is II it means you have Intel byte ordering. Each TIFF file begins with an image file header which then points to an image file directory which contains the image data and image information.|
