It appears that the Dev Center at Apple just updated its documentation set today. If you're using Xcode 3.2 and you want to update your documentation, you might be looking in the wrong place.

Before 3.2, you used to update your documentation in the Developer Documentation window (Help > Developer Documentation, or Command-Option-?). Now you'll find your documentation sets in the Xcode Preferences window (Xcode > Preferences... or Command-, and then choose the Documentation tab). Also, if checked, Xcode will automatically update your documentation when you launch it.

This Documentation panel offers subscription options for installing a documentation set (such as, for example, Mac OS X Legacy Library or iPhone OS 2.2 Library) as well as a handy Check and Install Now button that lets you request the latest updates. Use this to keep on top of the latest documentation updates.

Thanks, Scott Lawrence and @zadr

Once again, it's time for another edition of Ask TUAW: the place where we try to answer all of your Mac and Apple-related questions. This week we're taking questions about recovering pictures from corrupted compact flash cards, Twitter for the iPhone, extending iPhone battery life and more.

As always, we welcome your suggestions for this week and questions for next time. Please leave your contributions in the comments for this post. When asking questions, please include which Mac and which version of OS X you're running. If you don't specify, we'll assume you're running Leopard on an Intel Mac.

Okay, let's get to it!

Nick F. asks:

I've got some pictures I need to recover from a corrupted Compact Flash card. What's the best, preferably free, software to do it on my Mac?

This is one of those questions that can get frustrating if you're a Mac user. On the Windows side, there are a few good (and free) pieces of software that can help you accomplish this task. For the Mac, you're choices are mostly limited to pay applications -- at least if you want good results. Fortunately, these pay applications are very good.

For my money, the piece of software that works best when you want to recover pictures from a bad CF or SD card is Klix ($29.95) from Joesoft. I've used it quite a bit with clients, and on my own bad cards, and each time it performed flawlessly, recovering every lost picture from the card. Other alternatives for the Mac include CardRaider ($19.95), PhotoRescue ($29.00) and Data Rescue II ($99.00).

I realize that $29.95 for a piece of software might seem like a lot to some people. But if the software is easy to use and works as advertised, I think it's a worthwhile investment in the long run. Besides, it would cost far more to go back and take those vacation pictures you lost on the card again when you could buy Klix and recover them from your bad card instead. Given that, a program like Klix is actually a bargain.

If you've got Windows running on your Mac (either through Boot Camp or virtualization) and you've had good luck with one of the tools from the other side of the fence, let us know in the comments.

For this edition of Ask TUAW we've got questions about preventing an external partition from automounting, printing text selections, getting email from an Exchange server, syncing the Address Book with Google contacts, and more.

As always, your suggestions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions!

Being the Kool-aid sipping, Apple fanatic that you are, I'm sure you have already updated to the latest versions of iLife and iWork, right? If you have then it's not unlikely for you to be experiencing the same kind of problem that Rob Griffiths over at Macworld is dealing with as well.

Following his recent upgrade to the latest (and greatest!) version of iPhoto, Rob noticed some inconsistencies in the way Help was providing him information. Specifically, he had trouble with locating documentation on the new Faces feature when navigating through iPhoto's Help menu and launching the Help application. Rob was able to locate the documents he sought by using Leopard's Spotlight-esque Help-searching feature and querying for "Faces."

During our review of iPhoto '09 we did not come across any issues with the Help documentation. But we here at the TUAW headquarters at the Winter office in Hawaii are too stubborn to read directions. Rob's problem seems to be an old one that has occasionally plagued users through many versions of OS X. He points to another article at Macworld by Chris Breen which covers some tactics for wrangling Help back into line.

The culprit in this whodunit case turns out to be Help's cache file (in the library with the candlestick). According to Rob, "Help relies heavily on cache files to present its information to the user." For reasons unknown, upgrading an application does not necessarily cause the cache files to rebuild. In order to force the system to accomplish this, first quit iPhoto then navigate to the current user's home directory -> Library -> Caches (~/Library/Caches) and locate "com.apple.helpui." Once the cache file is located, drag it into the trash and restart iPhoto. Boom! You now have a working-as-intended iPhoto Help viewer.

While any application's help cache can become obsolete, Rob notes an increase in likelihood for Apple's own applications. Whether you're experiencing problems with an Apple app or not, deleting the cache file is very likely the solution. Have you had any issues with an application's help viewer? If so, which app was it and how did you resolve it? Let us know in the comments!

Note: This tip is Leopard-only, sorry Tiger holdouts.

The Command-? trick is easily one of my favorites among the less-ballyhooed feature expansions of Leopard. If you missed that one, it allows you to search for menu items in any application by pulling down the "Help" menu, which can be triggered from the keyboard with the Command-? (Command-Shift-/) shortcut. Typing the first few letters of the menu item you're searching for will highlight its location in the dropdown menus. I use it a lot, but somehow missed one great capability noted by TUAW reader Maarten: in Safari, the menu item search extends to your bookmark collection and Safari history!

Because the bookmarks and history items are contained in the menubar's menus, they're searched along with the other menu items, allowing blazing-fast navigation of the sites listed in the Bookmarks and History menus. I like speed; I have my bookmarks toolbar set up with numbered titles which correlate to their Command-number shortcut (the first non-folder item in the toolbar can be accessed with Command-1, the second with Command-2, etc.), and I have keyword shortcuts assigned to my other most-accessed bookmarks using various tools. There's only so much room in my life, however, for organizing bookmarks and assigning keywords. History search can be a tedious prospect, too, even using Spotlight or Safari's History menu hierarchy. This trick provides instant search and it's only a keyboard shortcut away. Because the History results are sorted into sub-menus named by date, the results from the history menu appear with their access date first, so it's easy to navigate the results to find what you're looking for.

The concept behind this tip applies to all kinds of applications. I started experimenting and found that the search bar in the help menu almost always included recent documents and open windows ... basically anything the application lists in its menus. The bookmarks/history search works in most other browsers, too. I use Firefox as well as Safari, so I was happy to find it worked there, with one minor caveat: the Command-? shortcut in Firefox opens the Firefox Help webpage, not the Help menu item, requiring a mouse click to focus the search box in the dropdown. I haven't found a way to add shortcut keys for top-level menu items in System Preferences, so if anyone knows that, or another way to access the search menu via a shortcut key, I'd love to know about it.

Happy searching, and a big thanks to Maarten for the tip!

If you're going to be a new iPhone 3G owner this week, you might want to make a note of this site to help you get acquainted with your new mobile device.

Apple has a guide to the iPhone available at http://help.apple.com/iphone/guide that you can view directly in MobileSafari, so you'll always have it when you need it.

The guide has help for Phone, Mail, Safari, iPod, Applications, Settings, the Wi-Fi Music Store, and some Troubleshooting tips.

I even learned something new: you can scroll to the top of web pages by double-tapping the title bar. Nice!

Thanks, Rubinnz!

Update: Major poopie! Apple has taken down the site for some inexplicable reason. I'll try and find out where it's moved to (or a mirror) and get back to you.

Update 2: It's back, and its contents are updated for the new iPhone software. The new guide includes tips for enterprise users, and for using the App Store. It seems to be oddly not fitting in MobileSafari's display window very well, but hopefully that will get sorted out soon.

Over at Mac OS X Hints I recently ran into this doozy of a hint that I somehow missed on its first go around. Basically the idea is to capitalize on a great new feature in Leopard's help. You can get to any menu item without your mouse by activating the help menu with the keyboard shortcut ? + ? (i.e. ? + shift + /). Then type the name of the menu command you want and scroll down to it with the arrow keys. That command's menu will automatically drop down with the item highlighted, hit enter and you're done! If you're a keyboard maven this is a really easy way to get to your menu items (though you can also activate the menubar from the keyboard with ?F2).

Thanks Brandon!

When I posted the new System Preferences pane in Leopard earlier this week, I was a little disappointed to see that while the desktop had changed (here it is online, if you want to make it your own already-- thanks, Ryan D!), the screensaver had not. I figured this is because Apple wasn't bringing any new screensavers to the fold in Leopard, but that was premature-- here's a "Falling Photos" screensaver sent to us by Christian BS (thanks!). I would be very, very surprised if it didn't automatically pull photos from iPhoto for you, as apparently "you can display any photos this way." Also notice the clock-- we're told that it can be displayed on any screensaver you choose.

And he also sent us this video of the new Help system, which has a Spotlightesque bar in it that will actually let you search for clickable options. That's terrific-- no more browsing through a Help system to find a tutorial about how to increase the text size: in Leopard, you'll be able to type "text size" into the bar, and automatically get the commands right within that menu.

Adium 1.0.1 is a great (and long-awaited) release for the free & open-source multiplatform chat client. The work, however, continues, and the Adium developers are politely asking for your help. First, there are a slew of items that need user feedback, and you can do that, right? Second, additional skilled devs are wanted so that some of the "cool but challenging" features on deck (video and audio chat, anyone?) can be tackled. Let's show the fine folks behind the quacking some TUAW love.

Thanks Nik!

Did your brand new iTV just go on the iFritz? Or possibly your iPhone took a cue from Mr. Jobs and prank called Japa-

Wait, they aren't out yet?

Well, maybe these two shiny new pre-release Apple Discussion forums, one for the Apple TV and another for the iPhone, will still come in handy for chatting about everything you need before you lay down your credit card(s). Topics are already flying in these forums, such as whether the iPhone's EDGE data speed is really all that bad, how much the data plan will cost in the first place and how to get your DVD movies into iTunes for transmission to the Apple TV. With all this chatter going on already, you should be well-prepared once these products actually land.

Last week we issued the first call for questions for the Ask TUAW weekly help column and now it's time to take a shot at some answers. Thanks to everyone who submitted a question. And since we'll be back next Wednesday, we want to renew the call for questions. Please submit your question via the comments page (put Ask TUAW in the subject), or just by leaving a comment to this post. Although we will try to be as helpful as possible, we may not be able to answer all questions. And naturally we invite our other readers to pitch in with suggestions as well.

Read on for this week's questions.

Beyond a doubt, Apple's retail stores have been and still are making headlines of all kinds - from business magazines hailing the stores' sleek design, to consumer reviews giving the stores high marks for their unique and (ideally) helpful Genius Bar feature. However, as some of you may know - not everyone's trip to the genius bar wraps up with a happy ending, and I'm not just talking about the customers; the Geniuses don't always have it so peachy-keen either.

Hence, Ungenius - a blog by "JC" who apparently has some stories to tell of his adventures "aton[ing] for the sins of a multinational corporation during nearly four years as a Mac Genius". JC delves into all sorts of topics surrounding the world of the Genius including QA, the obvious defects that have made headlines as of late, and even some thoughts as to why Class Actions might be bad for consumers.

Whether you've made a shrine for the last Genius who helped you out of a pickle or you're putting the finishing touches on a Genius Voodoo doll as you read this, Ungenius might be an interesting read from the other side of the cheery Apple retail store fence.

I'm delighted to see ifoAppleStore reporting that Apple will be releasing a new series of brochures and employee t-shirts in their retail stores to advertise the wide range of creative capabilities their Macs and software offer to consumers. The cover of the 12-page brochure (pictured) seems largely focused on advertising all the content-creating doors their award-winning iLife suite opens, while the inside of the brochure features various Apple Store employees wearing t-shirts with help-related slogans such as "I can help you go from shutterbug to photocaster."

Other strong Apple Store advantages that the brochures boast are the various Creative, Genius and Mac Specialist employees staffed at the stores who are trained to accommodate the various interests, hobbies and professions that Mac users have. The brochures advertise many more unique facets of the Apple Store and Mac-buying experience, such as their free workshops and on-line Concierge appointment scheduling service.

While I haven't been in an Apple Store in a while, all I remember from my past experience is advertising that was almost entirely focused on making me buy an iPod. It's great to see Apple putting their best foot forward with a campaign like this.

[Thanks Benjamin Bowles]

Earlier today while reading Splorp, a favorite blog of mine, I came across this post. Seems that, buried deep within the help files for Apple's DVD Player is the screen depicted at the right, which mistakenly lists Canada as a U.S. territory. We may share some land mass with our next door neighbors, but that's really where it ends. See a full version of the screenshot in Splorp's Flickr account. Oops.
