Welcome back to Mac 101, our occasional series of tips for new and novice Mac users.

Over the past 25 years, icons may have become ubiquitous almost to the point of fading into the visual background; still, the little pictures that began in 32x32 black and white format have grown up quite nicely into the massive 512x512 icons we enjoy in Mac OS X 10.5 Leopard. Although the list and column views are more utilitarian for most file management tasks, there are times when icon view is the way to go.

You can control whether or not a particular Finder window displays in Icon view via the View Menu ("as Icons," or ⌘-1), and then adjust the display size of the icons via the View Options inspector panel (⌘-J). You can get up to 128px square icons in Finder windows, which is plenty big, but what if you want to see all the graphical power of those fully operational battle icons?

One way to see the full-size icons is via Cover Flow -- simply switch your Finder window to "as Cover Flow" (via the toolbar button, the View menu, or with a quick ⌘-4) and you can scale your icons at will by adjusting the window size. If you prefer not to have that black background around your icon, however, what is there to do? Thanks to Rob Griffiths at Macworld & MacOSXHints, here's a great tip for getting the maximum size out of your icon previews in the Finder without resorting to Cover Flow.

To view icon previews up to 512x512, hit the Spotlight search field at the top right of the window; search for a null string (two quotation marks next to each other, no space in between, like so ""), then change the search target from This Mac to Current Folder and the search type from Contents to File Name. Switch to icon view and you'll see, at the bottom right corner of the window, a scaling slider. Push it to the right to maximize your icon size. It's just the thing for appreciating the fine detail on your bottle of unicorn tears. (If you're looking for the CHOCK LOCK and Rick Astley icons above, they're in the QuickPix 2008 pack from the Iconfactory.)

Rob also hazarded a guess that we might see a more accessible version of this feature in future Mac OS X versions. If you watched the Snow Leopard stealth preview video posted earlier, you know he may well be right.

Quick! The boss is coming! Hide your screen! What, you don't have Spaces set up so you can switch to that handy Excel worksheet you've got open? That's okay -- just put your display to sleep.

Of course, there are other reasons to want to quickly turn off your display, but they all have one simple key combination: Control + Shift + Eject.

It works with both desktop and laptop Macs. Moving the mouse or pressing a key on the keyboard wakes it right back up when you're ready.

Of course, if you want to put your whole computer to sleep, you can use Option + Command + Eject. There are other helpful shortcuts, too, in this article deep in the TUAW archives.

Thanks to our own Michael Rose for this one. Want more tips and tricks like this? Visit TUAW's Mac 101 section.

• Scroll -- If you're in a long document, or webpage, you can easily scroll through it by moving two fingers, side-by-side, up and down the trackpad. This feature works in almost any application.
  
• Rotate -- If you're in Preview.app or iPhoto, you can easily rotate a photo by rotating two fingers (like twisting off a bottle cap). This will work in only a few Apple applications, and may work with some third-party apps.
  
• Pinch Open and Close -- In Preview.app or iPhoto, you can zoom in on a photo by "pinching" the trackpad using two fingers. This is similar to the way you would zoom a photo on the iPhone.
  

• You can launch Exposé by swiping four fingers downward on the trackpad. This will allow you to view all open windows as tiles on your screen. This is the equivalent to using fn + F9.
  
• You can view your desktop by swiping four fingers upward on the trackpad. This will allow you to see everything on your desktop, without the clutter of open windows. This is the equivalent to using fn + F11.

• While reading your email in Mail.app, try swiping three fingers up or down on the trackpad. This will allow you to move to the next / last email without clicking or using the arrow keys.
  
• While in browsing the web in Safari.app, try the two-finger "pinch" to zoom in on text. You can also use three fingers to swipe back and forth through the recent browsing history.
• If you want more cool multi-touch trackpad features, check the "Trackpad" section of System Preferences.

• If your Mac is new: Boot up the new Mac and go through the setup screens. When the setup assistant asks if you want to migrate information from your old Mac, choose "From Time Machine backup or other disk."
  
• If your Mac has an existing account, don't fret. Just open "Migration Assistant" located in /Applications/Utilities.

New to the Mac? Welcome back to our Mac 101 series, which explores the basics of Mac OS X, provides tips and tricks, and dives into key features of Apple's bundled applications.

Address Book is the contact management software bundled with every new Mac. It's easy to use and well integrated with Mail and iCal. Let's explore some of its capabilities.

Creating a new record

There are three ways to do this. The first is to select "New Card" from the "File" menu. The second is to click the "+" icon below the "Name" column. Finally, you can press Command - N on your keyboard.

Next, fill in the fields. Some have drop-down titles. For example, you can label a phone number as "work", "home" or "mobile". Finally, you can add a note to the notes field.

Adding a photo is fun. Just click the photo box next to a contact's name and a new window appears. From there, you can browse to a photo on your computer or take a snapshot with your iSight camera. You can even apply some filters to the photo by clicking the Filters button on the right hand side of the window. That photo will appear on that person's record, on email messages retreived with Apple's Mail and on a synchronized iPhone or iPod.
