Here's a neat trick if you want to zoom in on an image while using Quick Look. Hold down the Option key while your mouse is hovered over the image, and it will change to a magnifying glass. Once you've zoomed in, drag the cursor, use the scroll wheel, or two fingers on a trackpad to move around the image. Press Option-Shift, and then click on the picture to zoom out.

To see this tip in action, check out the brief video above. Nothing too complicated, but definitely a fun and easy way, built directly into the OS, to browse around and inspect a picture file without opening a much heftier app like Photoshop.

As you've probably noticed, there are suddenly a lot of Safari Extensions floating around, thanks to the new features in Safari 5. PimpMySafari is ramping back up, and the Safari Extensions Tumblog is doing a great job of keeping track of all of them. I'm going to wait until the dust settles, the cream rises, and several other clichés come to pass before I dig in and start featuring my favorites. I do, however, want to offer a quick tip for dealing with Extensions that add toolbars.

Most of the Extensions I've tried that add a toolbar to Safari don't make it easy to show and hide it (and I don't really need every extension I install polling my keyboard, anyway). Aside from my url bar, my bookmarks bar, and my tabs, there's no toolbar in the world that I want to have open all the time. What is this, Firefox? Fortunately, there's a simple way to add shortcuts to show toolbars when they're useful, and hide them when they're irrelevant.

Ever wonder how your documents go from screen pixels to paper printouts? CUPS is the open source printing system that powers Mac OS X output, built for a variety of UNIX systems and now developed (or at least assimilated) by Apple. It provides print services by creating a representation of the page contents, and converting that data into formats that any number of printers understand.

OS X applications don't need to know the printer specifics. All they have to provide is a page description, which they pass along to the CUPS server. The server takes over from there and sends the document data to the active printer.

You can access your CUPS-based printers via a Web administration page, if the mood strikes you. It's easy; point your Web browser to http://127.0.0.1:631/printers. From there, you'll be able to check print queues, show completed print jobs, and more. You'll also be able to print a test page, pause the print queue, cancel all jobs, and set the default printer -- among other maintenance and administrative tasks. Most of the things you'd do there are also manageable via System Preferences, but it's nice to know what's underneath.

The recent launch of Steam for the Mac has brought a great deal of focus on the Mac's graphics capabilities. Specifically, it's led many Mac users to wonder whether Steam's games will run well (or at all) on their Macs. One of the potential points of confusion is Valve's assertion that Steam games aren't recommended for Macs with integrated graphics cards. That leads to the question: why not? What's the difference between integrated and discrete graphics, and which Macs have which?

TUAW reader Cody Rogers wrote in to say: "I'm fairly new to my iMac and Macbook Pro running Snow Leopard. One of my biggest annoyances from switching over from PC to Mac is when a dialogue box comes up and says 'cancel' or 'okay' I can't find the keyboard shortcut to go from cancel to okay. In Windows, I could just hit 'tab' to go to the other option. Is this possible on a Mac? I've been doing some searching on it and can't find anything!"

I happened to have found the same thing when doing a clean reinstall of Snow Leopard over the weekend. The good news is that there is a way to do it, but it is not turned on by default and it does require a bit of hunting around. I didn't remember where it was either.

1. Launch System Preferences, either by choosing it from the "Apple" menu or by going to your /Applications/ folder.
2. In System Preferences, select the "Keyboard" preference pane (middle of the 2nd row)
3. Then click "Keyboard Shortcuts" at the top of that window (see image above)
4. At the bottom of that panel there is an option to use Tab to move between either "Text boxes and lists only" (default) or "All controls".

Select the radio control next to "All controls" and you will now be able to use the tab to go between "Save" and "Cancel" or any other dialog boxes which appear.

Also note that for most dialog boxes, the Enter/Return key will select "OK" and command+period (or the Escape key) will cancel.

If you'd like to learn more about using keyboard shortcuts with Mac OS X, Apple has a really useful page which will come in handy, especially for those switching from Windows.

One of the adjustments those new to the Mac need to make is to familiarize themselves with the Command key. Although I switch hit and use Windows at work and a Mac when I'm not working, I've always preferred it over Control. Its proximity next to the space bar allows me to use my thumb, as opposed to my pinky finger with the Control key, for keyboard shortcuts. I find it particularly faster for copying and pasting.

The clover-looking key (it's actually an infinite loop), which had always been accompanied by an Apple logo until recently, sometimes behaves in ways similar to the Control key in the Windows world. At other times, however, it doesn't. Whether you're a recent Mac switcher or a seasoned Mac user, here are some shortcuts using the Command key to help you speed your way through tasks.

Let's face it: unless you're just casually surfing the Internet or playing a game, chances are pretty good that your hands are on the keyboard most of the time when you're at the computer. Sure, the mouse is only a few inches away, but wouldn't it just be easier if you didn't have to keep going back and forth from the mouse to the keyboard?

Enter the world of keyboard shortcuts. A keyboard shortcut is exactly what the name implies: a way of using the keys on your keyboard to quickly perform tasks that typically would require multiple steps using a mouse. Before we dive in to the magic keystrokes, let's take a quick look at how shortcuts work on the Mac.

Adjusting the volume on your Mac via the keyboard is pretty easy: there are 3 buttons, one for Volume Down, one for Volume Up, and one for Mute.

When you adjust the volume, a sound is played to help you determine when it is loud enough or quiet enough. Most times I find this helpful, but sometimes I want to adjust the volume without hearing the noise. To temporarily disable the "volume change" sound, hold down the shift key while you adjust the volume. You will see the visual indicator on-screen, but no sound will come out.

For example, on my iMac keyboard, I can increase the volume by pressing fn+f12, but if I press fn+ shift+ f12 it will increase the volume without making any sound. Very handy especially if you are in a meeting or working in a library, etc.

(Thanks to TUAW reader @webgalpat for that tip!)

But what If you never want to hear the sound when you adjust the volume? Go to "System Preferences.app" and then click on the "Sound" preference pane, and UNcheck the box next to "Play feedback when volume is changed" (That tip and others were covered in our recent 5 Tips for Switchers article.).

Now let's combine those two tips: what if you have changed the preference so that the sound is not normally played when you adjust the volume but you decide that just this once you want to hear the sound level changes? In that case, just hold down shift while adjusting the volume and it will make the noise.

Bonus tip: you can use the keyboard to adjust the volume of your Mac, or mute/unmute it, even when the screensaver is on -- without entering your password or disabling the screensaver.

As Apple removes sexually suggestive apps from the App Store (and is evidently preparing a Red Light District for the future), users are wondering how they can protect their kids from certain content. With that in mind, here's an overview of the parental controls in iTunes.

Note that the screenshot at right is from iTunes 9.0.3. Older versions look slightly different. Parental controls are only available in iTunes 5 and later.

To access these settings, select Preferences from the iTunes menu, and then click the Parental tab. Here you've got several options.

First, you can disable access to podcasts, internet radio or the iTunes Store completely. Note that you can keep iTunes U accessible while disabling the rest of the store. Additionally, you can deny access to shared libraries. Once turned off, these items won't appear in the left sidebar of the iTunes window.

Ever since you've started using your Mac, you've been looking at those icons towards the top right of your display in your menu bar. These items can direct to many different things, from connecting to a wireless network, to finding items on your Mac. These items not only can be clicked on to show a pop-up menu to perform actions, they can also indicate activity depending on what that icon if for. Here's a summary of some of the most widely-used icons, some menu items you might not have seen before on your Mac, common applications that have uses for menu items, and some extra functions in these items.

Spotlight: The Spotlight menu item provides an easy shortcut to finding files on your Mac. Clicking it will show a search box directly under the menu bar, and will provide a summary of results when searching. This icon will also indicate when your Mac is indexing new search results, like when you plug in a external hard drive, by a pulsing dot inside the magnifying glass.

Bluetooth: This icon (which is a Bluetooth logo) will show the current status of Bluetooth on your Mac. If Bluetooth is turned on, it will simply show the Bluetooth symbol. If it's turned off, the item will appear faded. If the Bluetooth part has been unplugged, it will slow a line and it will also appear faded. If your Mac is connected to a Bluetooth device, it will show three dots along with a faded Bluetooth logo. If your Mac is connected to an Apple Wireless Keyboard or Mouse, there will be a low battery warning displayed on the icon if their batteries are running low.

The iTunes Store and App Store have mastered the art of the impulse purchase. "Only two bucks? Sure, why not?" The good news is that you can send a song, album, movie or TV show to a friend just as easily.

Let's start with music. First, find the album or song you'd like to send. If you're sending a song, you'll see a drop-down arrow next to the track's "Buy" button. Click it to reveal the menu at right, then select "Gift this song."

You're brought to a new screen (in the gallery below). From there you only need to enter some information, click continue and you're done! Your recipient will receive a nice email message with a download link. The process is the same for albums, individual TV shows, audiobooks (though the "Gift this audiobook" looks different) and movies.

Note that you can't gift entire TV seasons (bummer) or iPhone/iPod touch apps. However, you can opt to share a link to an interesting app. With the app selected, click the same drop-down button to reveal the "Tell a Friend" option. The same is true of Podcasts - hit that "Tell a Friend" button to let everyone know what you're listening to. With just a few clicks, you can share your favorite content with anyone you want!

Text replacement: it's one of Snow Leopard's really cool features. With it, you can type abbreviations and they'll automatically expand into full text. You can convert your most common phrases into just a few keystrokes, and let Snow Leopard take care of the rest. Here's a quick summary of what you need to do to make text replacement work for you.

Creating Macros in System Preferences.

Open System Preferences (it's in the Apple menu at the top of your screen) and navigate to Language & Text > Text. There you'll find a Symbol and Text Substitution list. Click the + button to add a new item. For this example, put (tuaw) into the Replace column and The Unofficial Apple Weblog into the With column. Leave the box to the left of these items checked.

So why use the parentheses? Strictly speaking, they're not necessary. You can define text substitutions on any set of characters, as shown in the screen shot below. What these parentheses do for me, is that they distinguish between when I want to type TUAW and not have it expand, and when I want the abbreviation to transform into the full Weblog name.



Enabling Text Replacement

Text replacement works on a per-application basis. Many applications default to this feature being off. To make text replacement happen, right-click within any text entry area such as a composition window in Mail or the text entry field in Colloquy, etc. The contextual menu provides a Substitutions submenu. Make sure Text Replacement is checked. If it is not, select it to toggle the option from on to off or off to on.



Applying Text Replacment

The big secret to making text replacement happen, once you've defined the shortcuts and enabled Text Replacement in the contextual menu, is the space key. Snow Leopard does not apply the shortcut replacement until it detects you have finished typing a phrase. Only then does it perform its internal look up and substitution.

Also prepare to wait a second or so. The replacement text often lags behind your typing. So go ahead and keep entering text. The operating system will catch up and perform its substitution work without your oversight.

I love iPhoto. I use it for most of my photo editing. The thing I don't like about iPhoto is how it opens each and every time I connect my iPhone to my Mac. What strikes my as plain silly is that, since the introduction of the iPhone two and a half years ago, Apple has not built in an option in the iTunes iPhone status window to disable the automatic iPhoto launch every time you plug in your iPhone.

If you want to take control of this behavior, and you'd prefer to stick with Apple's built-in tools (rather than take advantage of the free and easy Cameras prefpane) there is good news: there's a simple way to disable this 'feature' and it doesn't involve command line stuff. Even better, it isn't an "all or nothing" solution – eg: you can still have iPhoto automatically open when you connect your camera, but not have it open when you connect your iPhone. Aron mentioned this approach a few months ago but I thought it would be helpful to walk through it in detail.

It should be noted that this solution only works on Mac OS X 10.6 Snow Leopard. If you are running 10.5 or earlier, you'll have to use one of the solutions noted above; we recommend the free Cameras preference pane as a quick fix.

You'll see the image above is of iPhoto's preferences. You may think the option of disabling iPhone auto-open is in there, but it's not. To stop the iPhone from opening iPhoto you actually need to launch the Image Capture application.

Step 1: Launch Image Capture (Applications>Image Capture). If your iPhone isn't plugged in already, plug it in to the USB port on your Mac. It should then show up in the devices source list.

Step 2: Make sure you have the iPhone selected in the source list. When you do, you should see any photos you have on the iPhone appear in the right-hand column of the Image Capture application.
Step 3: At the bottom of the source list, you'll see your iPhone's name then, below that, you'll see the words "Connecting this iPhone opens:" and a drop-down menu. Select "No application." Now close the Image Capture app and you're done. No more iPhone opening up iPhoto, but your other cameras will still auto-launch iPhoto when they are connected!

RSS reader support has been a built-in feature of Mail.app since version 3.0 (when Mac OS X 10.5 Leopard was released). Although I subscribe to a number of RSS feeds, I've yet to find the need for a dedicated RSS reader app -- such as Newsgator's NetNewsWire.

I like having my email and news feeds in the same application. By default, RSS feeds that you subscribe to in Mail will appear in their own folder. If you'd like your RSS feeds to appear in your inbox, just click on the upward pointing arrow of an RSS feed(s) within the RSS section in Mail.app.

On the downside, this view of RSS feeds may flood your inbox and be overwhelming, depending on the number and the activity of feeds you're subscribed to. As a result, you may want to be selective in choosing your feeds. However, I've found this view particularly handy with time-sensitive feeds, and have used it on numerous occasions to score in-demand concert tickets (at face value prices, too!) with search-based Craigslist feeds.

The video shows hints about keyboard shortcuts (such as using the Command key on a Mac instead of the Control key on a PC), and using Command-Option-Escape on a Mac to force-quit an application, much like Control-Alt-Delete does on Windows. There's also tips on using the mouse on a Mac, and using the trackpad to perform gestures to get around your laptop.

Switchers are also going to need help on controlling windows; closing and minimizing controls, of course, are on the top left of windows on a Mac, much like the buttons on the top right of a window on Windows. There's also tips on the differences and how to adjust to similar features and applications on a Mac, like the differences between Windows Explorer and the Finder on the Mac, and what parallels there are between other bundled applications. Finally, there's also tips on which web browser to use, how to eject a disc, and where to go for help.

If you've got a friend or family member who's new to Mac OS X, it's something they should check out to help get used to using the Mac. Of course, right after that, the next step is to read through our library of Mac 101 tips and tricks for novice Mac users.
