It's easy to fill your iPhoto library with pictures. However, the task of finding the ones you're after isn't. The Events feature of iPhoto '08 is helpful, and you can improve it with Keywords.

Think of keywords as tags. You can assign any keyword(s) to any photo, like "Suzie," "Summer" or "Beach." Then, simply search "Suzie" to find relevant photos, sorted by event. Here's how to do it.

From the "View" menu, select "Keywords" (or hit Shift-Apple-K). Next, click beneath your photos to reveal the keyword text field. Enter as many comma-separated keywords as you like; previously used keywords will auto-complete.

Here's an added bonus. You can also search by keyword via the Image Browser in Pages (see above).

Recently, I had to create a new admin user on an older 500mhz Power Mac G4 running OS 10.3.9. Needless to say, there was no 10.3 install discs to be found. What to do? Follow these simple (but powerful) steps.

First, restart the Mac while holding down the Command and "S" keys to start in Single-User Mode. Next, you'll see the UNIX boot sequence in white text on a black field. Don't worry, that's what we expected. At the prompt, type the following commands, hitting "Return" after each.

• mount -uw /
• rm /var/db/.AppleSetupDone
• shutdown /h now

Please be sure to type these commands exactly as presented here (sans bullets). "rm" is a powerful little command and if the syntax isn't right, you might unintentionally delete something important. Next, your machine will shut down. Turn it back on and you'll see the "Welcome to OS X" video, and be prompted through the process of creating a new admin user.

Other users on that machine -- including other admin users -- will remain intact. This is also a good way to change the password on an older admin account without the disc. Simply follow the same steps and, once you've logged in with the new account, change the password on your old account. Then, log in as the old account and delete the new one.

IntoMobile has a few good tips on how to extend your iPhone's battery life, and most of them involve the most obvious thing you can do to keep your iPhone running: cut down on any and all extra functions. They actually recommend to turn off 3G, but you don't have to go that far -- just by holding down the Home button, you can close any background applications sucking up juice. And by resetting your phone, you can do the same thing -- clear out anything running that you're not using.

Actually, while I was in Los Angeles last week, I heard the great Leo Laporte mention a great tip on his radio show: turn off the "Ask to join networks" feature in the WiFi settings. If you're like me, you almost always know when there's a WiFi network around that you can use on your iPhone, and so it's pointless (and a waste of battery life) for the iPhone to be constantly searching for one. You can always flip it back on if you do want to do a little poking around, but leaving it off will significantly help battery life.

In fact, when in extreme trouble, you can go even farther and just switch the whole thing into Airplane Mode. It'll make your phone useless, but when you really need it -- out on a trip, or waiting to make an important call -- the extra battery time might make all the difference.

As we know, the Finder offers four ways to display your files. Namely icon view, list view, column view, and Cover Flow. Perhaps you prefer one over the others (let's say column view), but your windows open to icon view by default. That can be annoying but here's how to fix it.

First, open a new Finder window. Next, select your preferred display method and then close the window without doing anything else. Don't open a folder, drag an icon, nothing. Now subsequent Finder windows will default to your preferred setting.

Is your laptop not among those that can do Multi-touch? Don't feel badly, you can replicate those great features!

Well, kind of. First, open an image with Quick Look. Next, hold down the Option key while performing a two-finger scroll. The image zooms in and out!

Finally, let go of the Option key but keep your fingers in place on your trackpad. The cursor turns into a four-point directional, and then you can pan the image within the Quick Look window.

This also works with a mouse and scrollwheel.

Thanks, Max!

A while back reader Michael Coyle was nice enough to send us this write-up on how to customize Leopard's Guest account, and just recently he sent along another guide that you might not need right away, but will come in handy when you really need it. He's got an in-depth look at how to create a custom menu style when authoring a DVD in Toast Titanium 8.

As he says, the default styles that come with the application are a little less than formal, so if you want to create a professional menu for the DVD that fits your needs, this will show you how. As far as I can tell, the style is just a Photoshop file with various layers for the DVD to use as a menu (selected, frames for videos and the border around them, and so on); so the trick is finding the right layers to edit and leaving everything else alone (so nothing breaks).

If you've got some DVD authoring in your future, and plan to use Toast to get it all done, there you go.

Here are two simple but useful tips from TUAW readers David B Alford and Andrew Akker that help you navigate through your iPhone or iPod home screens. David points out that if you tap just to the left or to the right of the dots at the bottom of your screen, you can move a page at a time without having to drag. Tap left, you move left. Tap right, you move right. It's quick and it's easy.

Andrew figured out how to pause his drag Home screen drags. If you start to move between screens by dragging and then tap the dots control during that drag, screen pauses. You'll see bits of both home screens at once, and can interact with them normally by tapping icons. You can see up to 24 icons at once (16 off to one side, 4 along the other side, and 4 in the bar at the bottom).

I've tested both tips extensively and they work great -- two really nice additions to one's Home-screens skills.

Widgets are way too much fun. Though your Mac ships with a few of them already installed on the Dashboard, frankly they're kind of boring. I mean, how much fun is a calculator, clock, or calendar? Did you know there's a bunch more hiding in the far corners of your computer, and even more waiting to be discovered online? Let's take a look at where to find the extra goodies.

Mac | Life has a huge roundup of "25 iPhone Power Tips"-- just in case you've been living under a rock since late June, here's everything you missed about the iPhone, from how to unstick a stuck slider, to using aluminum foil to insulate an audio cable from the iPhone's signal, to where to go for iPhone 411. Of course you're here already, baby, and if you haven't noticed, that we have a page completely dedicated to iPhone itself, then look no further.

Some of the tips are a little obvious (like #6: surprise, surprise, if you can't see the camera button while the phone's turned away from you, place your finger before you turn it-- brilliant!). And there are plenty of omissions-- I know for sure that Battlefleet, the best game I've seen on the non-jailbroken iPhone, is missing, and there's nothing at all about Installer.app or any of the craziness you can pull off with that. That's a big deal, even though it may be a little more underground than Mac | Life wants to go.

But there's some good info here, especially if you've just recently plunked down the cash to AT&T and want your tips all in one place. Just make sure to come back here and pay attention when you're done.

As I understand it, there are a lot of new DAPs and music-enabled mobile phones that support A2DP - a technology that allows devices to transmit stereo audio to Bluetooth headphones. It's all the rage with the kids these days, and many fans of cutting cables wherever possible were a bit disappointed when the A2DP acronym didn't make the iPhone's feature list. Thanks to a tip from TUAW reader Earle Davies though, the iPhone apparently does seem to support sending any audio - including music and the audio tracks from your videos - to a Bluetooth headset that isn't even enabled with A2DP - but it aint pretty.

To tinker with this, you of course need to have a Bluetooth headset paired with your iPhone. I personally have an older HS-850, one of the first Motorola models with a microphone that flipped open to toggle the headset on and off. After you've switched your headset on and it's shaken hands with your iPhone, go into the Visual Voicemail screen and tap the Audio button in the upper right (which is otherwise a Speaker button when your headset isn't on and communicating with your phone). You'll receive an audio selection dialog much like the in-call dialog that allows you to chose where to send the iPhone's audio. As you might guess, select the Headset option, then switch over to the iPod and begin playing music or a video. This, unfortunately, is why I had to include 'kinda' in this post's headline - while the iPhone sends audio to both Earle's Motorola H700 headset and my HS-850, it still plays audio though the iPhone's speakers as well. It's a bizarre quirk I can't seem to figure out how to stop, which makes me think this is either an unfinished feature or, perhaps more likely, simply a side effect of some of the iPhone's functionality.

Whether you can use this trick to get the iPhone to send stereo audio to a true set of Bluetooth headphones I couldn't tell you, because I own no such headphones. If you readers tinker with this more and help uncover more of what's going on here, please sound off in the comments.

I mentioned simple Safari downloads in my recent iPhone ringtones post. Several readers contacted me asking if I could give a step-by-step description how to do this trick.

The problem with downloading audio and video through Safari is that if you paste the link directly into the Address bar, the resources load into the Safari window. They don't download directly to disk.

The easiest way to handle this is by right-clicking (control-clicking) a music or video link and selecting Download Linked File from the pop-up menu. However if you get your URL outside Safari and don't have a link to right-click, that method won't work. In the ringtones example, the URL was copied from a text file.

To download a URL directly then, go into Safari and select Window -> Downloads. The Downloads windows open. Select it and paste your URL (Edit -> Paste or just type Command-V). The download begins immediately without having to open the file in an intermediate window and then save to disk.

This trick has been tested with Safari 3, and several people have told me that it works for them in Safari 2. Let me know in the comments how it works for you. I tried it out in Firefox and can confirm it does not work there.

While typing on the iPhone is an arguably difficult / easy process depending on who you are, I figured out a handy tip for saving at least one button press - as long as you're going to a .com site. Just like a real browser, it appears that the iPhone will allow you to type in most .com URLs without having to type the actual .com or pressing the button. Simply press Go after typing the site name and MobileSafari should automatically insert the .com for you. It's worked in every site I've tried so far at least. A mere savings of one button press to be sure, but in my opinion, shaving off even one repeated key press can amount to a lot of saved time after a while.

At TUAW HQ we absolutely love Quicksilver, the powerful, incredibly extensible and indispensable productivity tool, as it's capable of speeding up just about any conceivable operation on your Mac. Still, with everything Quicksilver is capable of, I honestly never thought it could be used to help you print documents faster. Sure enough, I have been taught my lesson to never doubt Quicksilver's reach by Mark Fisher, author of this Faster Printing with Quicksilver. In summary, Fisher's how-to walks you through adding your printer to Quicksilver's catalog so it can be used as a target for sending files to print. Combined with the Quicksilver comma trick, you can send multiple files to your printer at once, all from the streamlined efficiency of Quicksilver's search interface.

One downside to Fisher's tip, however, is that it requires a bit of digging around in Quicksilver, not to mention a decent workout training oneself through the app's arguably steep learning curve. If all this tinkering simply isn't your bag, there's a much easier trick I wrote about last year for creating a drag-and-drop desktop printer. This is much easier for virtually anyone to set up for themselves, and as a commenter on that post mentioned, you can drag that desktop printer to the right side of your Dock and delete the Desktop icon altogether, saving precious space for... well, probably all those documents you need to print off to begin with.

Ultimately, either of these tips are a great way print your documents more efficiently, as they remove the need to open each individual app and print the documents manually, one by one.

The iPhone offers some delightful navigation tricks in Safari. Here are a few of my favorites for you to enjoy and to use while scrolling though webpages:

Page down. When not using a zoomed-in display, double-tap towards the bottom of the screen. The page will re-center around your tap. Make sure not to tap a link!

Jump to the top. Double-tap the very top of the screen, just below the time display to pop back to the top of the page. (Thanks John C)

Zoom onto a single picture. Double-tapping images in Safari zooms them to fit your iPhone display. If the picture is linked to a URL, this can prove a little tricky but it works great for non-linked images. Double-tap again to return to the unzoomed display.

Zoom a column. You can zoom text columns as well as pictures. Double-tap on the column to fit it to the display. Double-tap again to return out of the zoom. Not only does Safari zoom block-quoted text independently of regular text but if you move your finger after the first double-tap-to-fit, it interprets the next double-tap as a re-center page command rather than a return-to-previous-zoom. Smart.

Stopping a scroll. After flicking a page to get it to scroll, you can tap the page at any time to stop that movement. Don't forget, you can also manually drag the screen display to reset the part you're viewing.

Manual zoom. This is probably one of the most-advertised Safari features (along with the flip-the-phone-on-its-side-trick) but it's worth mentioning again. To zoom into a Safari page, put your thumb and forefinger on the screen and move them apart. To zoom out, pinch the fingers together after starting with them apart.

Examining the URL. To peek at a link's destination, touch and hold the link for a few seconds. You can also do this with images to see if they are linked. If a link appears and you don't want to activate it, just slide your finger away until the destination text disappears.
