The new features include an innovative, if odd, vertical “accordion” tab.

“We have been actively working on the algorithmic transition of search, which was completed in August, and we are already releasing new features to the search experience,” said Shashi Seth, SVP of Yahoo Search and Marketplaces, in an interview with BoomTown today. “Since we are not actively spending a lot of energy on back-end stuff, we can focus our efforts on new things.”

Among the new enhancements to Yahoo (YHOO) search: A vertical “accordion” paradigm with shortcuts on search results that allow for new kinds of information presentation; “quick apps,” beginning with one for Netflix (NFLX) that lets its members add movies to their queue directly from the search results page; slideshows within search from the “Trending Now” lists on Yahoo; more immersive and theater-style photo and video search, as well as “the ability for people to view personally meaningful public Facebook albums from friends,” when they sign in to Facebook; and a new mobile search experience for Apple (AAPL) iPhone and Google Android smartphones, as well as feature phones, that uses HTML5 technology.

“We wanted users to see that things had changed dramatically,” said Seth. “Consumer needs for search engines have changed.”

He said that in testing so far, engagement–an increasingly important measure for advertisers–had spiked with the new features, especially in “taking search from an information need to action at an end.”

Seth promised a “huge pipeline of stuff” to come in search, where the Silicon Valley Internet giant holds the No. 2 position in market share, well behind Google (GOOG) and ahead of the Microsoft (MSFT) Bing service.

Both Google and Microsoft have been adding a series of search upgrades over the last year, such as Google Instant, while Yahoo has not.

Yahoo has a blog post up about it here.

And here are some screenshots, as well as the official press release and an overview by Yahoo of the new search features (click on the images to make them bigger):

Yahoo! Makes Searching More Relevant, Productive and Fun

New features help people explore their interests and do more

SUNNYVALE, Calif., October 7, 2010–Yahoo! (NASDAQ: YHOO) today introduced new Search enhancements that will help millions of people be entertained, productive, and informed anywhere they are across Yahoo!. Leveraging Yahoo!’s rich content and robust technology platforms, these new Yahoo! Search features will help people get to the entertainment and news content they care about on all connected devices–and do more with the things they find.

“Our goal is to understand what people care about and to make it fun for them to explore the most personally relevant, interesting, and informative content so that they can get things done faster and stay in the know,” said Shashi Seth, senior vice president, Yahoo! Search and Marketplaces. “Yahoo!’s new immersive Search is a cornerstone of the overall Yahoo! experience, creating more ways to connect people with whatever and whoever interests them.”

To start using the new enhancements, go to Yahoo.com and search for topics such as “Lady Gaga” or “Wall Street: Money Never Sleeps.” The features include 3D multifaceted results and tools that let people:

• Cut to the chase–Intelligent shortcuts for movies, musical artists, celebrities and news topics conveniently organize the most important details such as images, articles, videos, tweets, event listings, and ratings. They also provide quick and easy ways to purchase movie or concert tickets while searching.

• Find favorite flicks–The first in a series of unique “quick apps” from Yahoo! Search, a new Web app for Netflix provides an easy way for Netflix members to add movies to their Queue right from the Search results page. In the coming months, Yahoo! plans to launch additional apps that change the search paradigm from finding to doing.

• Watch what’s happening now–Continuing to bring Search to more people in more places across Yahoo!, the company is helping people feed their curiosity by displaying image slideshows right above the standard results for interesting topics from Yahoo!’s Trending Now lists on Yahoo.com and elsewhere.

• Lean back and browse more pictures–An immersive new Yahoo! Image Search delivers engaging slideshows with public photos from Flickr and Yahoo!’s leading content sites, as well as the ability for people to view personally meaningful public Facebook albums from friends when they sign-in and connect their Yahoo! accounts to Facebook.

• Search on the go–Android and iPhone users can now get faster, more sophisticated Search results, thanks to the latest HTML5 technology. Rich content on entertainment, finance, and local topics is surfaced in more unique and compelling ways for high-end mobile devices.

Working toward its vision to be the center of people’s online lives, Yahoo! is dedicated to re-imagining Search by creating new ways to bring people closer to what they need and want on the Web. Today’s visually stunning new Search experiences throughout the Yahoo! network, along with innovative technology enhancements and quality improvements for rich local and shopping searches, all supplement organic algorithmic Search listings from the recently transitioned Microsoft search platform. Yahoo! expects current and future innovations to redefine Yahoo! Search and drive greater consumer engagement and loyalty.

New features began rolling out to Search users across the U.S. today, and Yahoo! expects to launch them for additional global markets in 2011.

Search Launch Overview Oct 2010

This week, I gathered up some useful shortcuts that come built into most of the BlackBerrys, even older models, made by Research In Motion Ltd. but not many owners actually use or know about them. Ironically, most of these shortcuts are conducted using a BlackBerry feature that the iPhone lacks: its physical keyboard. (The iPhone uses a virtual keyboard that appears on-screen only when needed.)

Some useful shortcuts are built into most BlackBerrys, even older models, though not many owners actually use or know about them. Most of these shortcuts are conducted using a BlackBerry feature that the iPhone lacks: its physical keyboard.

Some of these shortcuts are seemingly obvious, like number or capitalization locks, but others are more obscure, like codes that can be entered to display the BlackBerry’s precise signal strength. Some shortcuts are performed with a single keystroke; others work in conjunction with a trackwheel or trackball, depending on your BlackBerry model, and still others work when two keys are pressed simultaneously. BlackBerrys with condensed keyboards that use auto-correcting SureType may require extra or different keystrokes.

Navigation Simplified

A series of keystrokes work in various BlackBerry applications to make navigation much faster. Pressing the Space bar works like Page Down on a computer keyboard, moving down one screen per press. Holding Shift while pressing the Space bar moves in the opposite direction, like the Page Up key. To quickly move to the very top or bottom of a page, press “T” or “B,” respectively. Another way to page down or up through lists is to hold the ALT key while scrolling with the trackwheel.

Users can toggle between the BlackBerry’s running applications without the extra step of navigating back to the Home screen. To do this, press ALT and the Escape key, then release Escape and use the trackwheel to scroll through a display of icons that represent running programs until you reach the desired program, then release the ALT key to select that program.

Messaging Magic

Shortcuts in BlackBerry messaging can be a real boon when you’re trying to get work done quickly. While looking at a list of emails, hit “C” to immediately start composing a new email. When a specific email is highlighted, pressing “R” will reply to that message; “L” will reply to all and “F” will forward it. Hitting “J” while an email is highlighted will jump directly to the oldest message in that email chain.

A list of emails can be more neatly organized from the message screen by holding the ALT key and pressing a letter. “I” will alter the list to show only incoming emails, “O” will show just those emails that were sent. “P” shows a phone log, including dates and times, and “s” displays all SMS messages made or received on the BlackBerry.

In the body of a message, pressing the Space bar twice inserts a period and capitalizes the next word. When the left Shift key and ALT are pressed together, the keyboard’s number lock is on; the right Shift key and ALT work as the caps lock. Holding any letter down will capitalize it, saving users from pressing another key to do so. To type a letter with an accent, hold the letter key down while scrolling up or down with the trackwheel until you find the correctly accented letter.

Type Less, Say More

While composing emails, a series of AutoText codes can be typed in the email body to automatically display certain phrases or information. Typing “mynumber” and a space in the text of an email will automatically display your BlackBerry’s phone number. Similarly, when “LD” is entered the local date is displayed, and when “LT” is typed the local time appears.

If your email inbox is full and you can’t send emails, find out the PIN of your recipient’s BlackBerry and use it to message the person directly. (To find your own PIN, type “mypin” and a space into the body of an email. This code can be used to send PIN messages from one device to another without using the device’s usual email system.)

Geeky Codes

If you’re just dying to know some techie details about your BlackBerry, the “Help Me!” screen will be right up your alley. To view the “Help Me!” screen, press ALT, Shift and “H” simultaneously. This displays data that won’t matter much to the average person, such as the device’s vendor ID, platform and free file space. But it also shows the exact percentage of remaining battery power on the BlackBerry, which could be helpful if you aren’t sure how to interpret the imprecise battery indicator bars at the top of the home screen.

Another way to geek up your BlackBerry is to change its signal strength indicator from bars to numbers that tell how many decibels per milliwatt the device is transmitting. To do this, go to the Home screen and hold down the ALT button while typing “NMLL.” My BlackBerry displayed a minus 75 when I made this change. Strengths of minus 50 to minus 90 are said to be good, while anything higher, like minus 100, isn’t. Though this numerical indicator won’t likely be of any practical use, you could use it to turn to a friend and compare reception during an excruciatingly boring meeting.

One way to impress a technophile on a date is by pulling up a BlackBerry’s Event Log. To do this, go to the Home screen and hold down ALT while typing “LGLG.” This retrieves a long list of numerous confusing codes representing the functions that were performed on your device. The Menu screen in the Event Log gives users the option to clear this log, freeing up some BlackBerry memory, while an Options screen lets people set the log up to record only certain kinds of activities.

Finally, to reboot your BlackBerry without removing its plastic back and taking out the battery, press ALT, Right Shift and Delete simultaneously. More codes can be found in the blogosphere or in a special section of RIM’s Web site: http://na.blackberry.com/eng/support/blackberry101/tips/. Adopting just one of these shortcuts can significantly change the way you use your BlackBerry.

A fondness for TiVo has encouraged users to refer to it with designated nicknames and/or genders. A teacher friend of mine was recently asked by a student if her husband’s name was TiVo after the child heard her say she would have to tell TiVo about a new TV show. But like any old friend — or spouse — who has been around for a while, TiVo has a few tricks up its sleeve that might surprise longtime users and new owners alike. This column includes just a handful of those tricks and highlights some features that may make TiVo more useful. These tips are for everyday users, not serious hackers, and many others exist.

Remote-Control Codes

Each of these codes is entered one time to enable an otherwise-hidden function, and three chimes signal the code is set. These functions can be disabled by entering the code a second time, or if TiVo is rebooted.

Clock: If you miss having a VCR nearby to tell you the time while you watch TV, TiVo can help. A digital clock can be programmed to show up in the lower right-hand corner of your television screen by pressing “SELECT-PLAY-SELECT-9-SELECT.”

While playing recorded shows, this clock displays the current time and the elapsed time of the program you’re watching. Personally, I check a show’s progress by pressing the remote’s Play button to see the progress bar, and the Info button shows the current time. But the on-screen clock might come in handy when you’re watching TV on a terrible date and you don’t want to get caught glancing at your watch.

30-second skip: One of the glorious functions of TiVo and other DVRs is their ability to fast-forward through commercials. But it takes practice to know when to press Play so as to completely miss commercials.

If you’re unsure about your fast-forwarding technique, TiVo can be permanently set to skip ahead in 30-second increments, by entering “SELECT-PLAY-SELECT-3-0-SELECT.” This code must be set while watching a recorded show. After that, the 30-second skipping works whenever you press the “Skip To Tick” button, which looks like an arrow pointing right to a straight line.

TiVo says this code won’t work for longer time increments, like 90 seconds, and I tried using various increments, to no avail. Still, pressing this button about five or seven times in a row (depending on the show) gets you through commercials with less guesswork.

Disappearing progress bar: TiVo’s progress bar, which shows how far along a program has progressed in terms of the entire show’s duration, appears at various moments, such as when you first play a recorded show or unpause. This indicator lingers on the screen for just about three seconds, but if this seems too long, you can enter “SELECT-PLAY-SELECT-PAUSE-SELECT” to set the progress bar to disappear after less than a second.

I tried this setting on my TiVo, but one second showed only a quick blink of the progress bar, not enough time to see anything.

Number Shortcuts

From the TiVo Central menu, pressing each number on the remote control’s numeric keypad skips directly to a different tool. Some of the more useful shortcuts include pressing “1″ to go to Season Pass Manager (a list of programs that are set to automatically record every episode), “4″ to go to Search Title and “8″ to go to TiVo Suggestions.

Viewing Tips

TiVo can display a programming guide in a TV-Guide-like grid, or as a two-columned TiVo Live Guide that can list future shows for hours or days out. The top of Live Guide gives a detailed description of each selected program, along with its duration and TV rating.

The Now Playing list shows content stored on a TiVo. By default, this list is organized in time sequential order with same-series TV shows grouped into folders. Remote-control shortcuts re-sort this list: pressing “1″ switches from sequential to alphabetical order and vice versa; pressing “2″ ungroups shows to display each title; shows are regrouped into folders when “2″ is pressed again.

Lesser-Known Features

Universal Swivel Search is a way of seeing how TiVo’s various shows and movies are related to one another. It lists details about each program, including actors, directors, tags associated with a show (like love, dating and addiction) and suggestions of similar content. Swivel Search is accessed through the Find Programs menu or More Options while looking at a recorded show.

By selecting a Swivel Search detail about a particular show, such as one of its actors, you can see what else he or she starred in and whether or not that show or movie is available through TiVo or Amazon.com‘s Unbox. Unbox downloads movies directly to your TiVo ranging from $2 to $15 each depending on whether you rent or buy a movie.

Plenty of free Internet content can be downloaded from the Web to your TiVo. But TiVo confusingly places this content in two menus: Find Programs and Music, Photos, Products & More. Under Find Programs, a Download TV & Movies section offers Amazon Unbox movies and free TiVoCast content. The latter can be set to automatically download with Season Pass settings, such as The Onion’s weekly video or ExerciseTV’s twice weekly videos.

The Music, Photos, Products & More menu holds content like photos and unprotected MP3s from a nearby computer, podcasts, Rhapsody music, Yahoo! Weather and Traffic and on-screen games. You can even buy movie tickets through Fandango.

TiVo takes up valuable space in a home entertainment center, so it’s important for the company to make sure its content is varied and useful. The codes and shortcuts mentioned can change the way you use this valuable device every day.
