How to Open Attachments as a Full-Screen Slideshow in Mac OS X Mail

All the photos are in the email. It's a pretty and picturesque email. It is not a full-screen slideshow that progresses through the images automatically; or is it?

In Mac OS X Mail, you can save the attached files and open them in Quick Look, of course; or you open Quick Look directly from the message and progress to the slideshow from there. There's an even faster and more direct way, though.

Open Attachments as a Full-Screen Slideshow in Mac OS X Mail

To launch a full-screen slideshow of all files attached to an email (which can be viewed with Quick Look) in Mac OS X Mail:

• Open the email containing the attached images and documents.
• Hold down the Alt key.
• Click Quick Look (Slideshow in Mac OS X Mail 4) in the email's header area.
