One of the great new features of Leopard is Quick Look. With Quick Look, you can view images, documents and media files just by pressing the spacebar. If you're using Leopard, you've probably tried Quick Look in the Finder, but that's not the only place you can use it. Quick Look saves me time everyday as I use it in the Finder, in Mail, in Time Machine, and in third-party applications. Here are some ways you can use Quick Look.
Select an image in the Finder
and press the spacebar to open the image in the
Quick Look window. If you want, you can view the
image in full-screen by clicking the button at
the bottom of the window. When you're finished
viewing the image, you can send it to iPhoto or
you can exit Quick Look by pressing the spacebar
again.

You no longer have to open
documents to view their contents. Just select a
document, for example, a pdf file, in the Finder
and press the spacebar. You'll be able to view
the document and navigate through it with a
scroll bar. If the print in the document is too
small to read, click the button at the bottom of
the window to enter full-screen mode.

If you use the column view in
the Finder, you know that you can preview audio
and video files directly in the Finder, but the
image will be small. Instead of using the
old-fashioned preview mode, press the spacebar
after selecting a video and view it in the much
larger Quick Look window. Again, if you want to
view the video in full-screen, just click the
button at the bottom of the window.

If you use Mail, you know that
image attachments will often appear as inline
images in your message. But documents appear as
icons and you may not want to open an attachment
if you don't know what it contains. That problem
is eliminated with Quick Look. Just select the
attachment and click the Quick Look button on the
toolbar in Mail and you can preview the document
without opening it.

Spotlight is great for
searching but sometimes you can end up with a
long list of search results with odd names.
Knowing if a file is actually the one you're
searching for can sometimes be a challenge. Quick
Look, however, can come to your rescue by letting
you preview files in the Spotlight search results
window, just as you would in a Finder
window.

If you use Time Machine for
backing up your data, Quick Look can save you
time if you need to restore a file. Instead of
guessing if the file you found in Time Machine is
the one you really need, you can use the spacebar
to access Quick Look and preview the file before
restoring it.

If you're like me, your Trash
might sometimes fill up with many files and, of
course, it's at those times that you realize that
you need a file you deleted. Going through all
that trash can waste time but Quick Look can make
the task easier for you. Invoke Quick Look with
the usual press on the spacebar and you can
easily navigate through the files until you find
the one you need.

Some third-party applications,
particularly those that relate primarily to file
or document management, let you use Quick Look
with the application. For example, I use ForkLift
to transfer files from my computer to my
website's server and sometimes I need to check
that I'm transferring the correct file.
Fortunately, the developers of ForkLift have
incorporated Quick Look technology into their
application and I can use the spacebar to preview
a document before sending it to the server. If
you use third-party applications, try the old
"press the spacebar" trick and see if Quick Look
is available from the application.
