[edit] Overview
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, ASCII and RTF text documents, Apple Keynote, Pages and Numbers, ODF documents, Microsoft Word, Excel, and PowerPoint files (including OOXML), RAW camera images.
[edit] Activation
To activate Quick Look, select the document and press the space bar (or choose File > Quick Look, Cmd-Y) and the file will be viewable in a separate window. Press space bar again to close, or double-click the window to open the file with its default application.
Quick Look can also be opened in full screen by pressing Opt-Spacebar or Cmd-Opt-Y in the Finder. Press the Escape key (esc) to exit full screen.
Additionally, files like powerpoints,can be navigated with by hovering the cursor over the icon in finder and left and right arrows appear enabling the user to browse the slides within the icon, without having to even open up quick look itself.
