In iTunes Radio
Q. I updated the iTunes program on my computer to try iTunes Radio, but I can't find all those online radio stations that used to be under the Radio tab. Are they gone?
A. When Apple released iTunes 11.1 last week to coincide with the arrival of its iOS 7 mobile operating system and debut of the iTunes Radio service, it shifted a few things around. If the preset channels or build-your-own-station approach of iTunes Radio do not suit you, you can still find the online radio stations list under the Internet tab in the main iTunes window when you have the Music library selected.
Likewise, you can still listen to stations you find online by going to the File menu, choosing Open Stream and pasting the URL for that station's stream into the box. And saving a station to an iTunes playlist can help you find your favorite streams more quickly -- just drag the station name from the station list onto an existing playlist. If you have the iTunes Sidebar open on the left, drag the radio stream to the desired playlist in the sidebar panel. If you do not have the sidebar visible (the panel can be toggled on and off under the View menu), drag the stream to the right side of the window, where the Playlists panel slides open automatically.
Along with moving things around in the Music library, the iTunes 11.1 update adds a few other features, like the ability to sync with devices running the iOS 7 software, and a shuffle option for the iTunes Genius tool that groups similar-sounding songs together.
In the Podcasts library, you can now make personalized "Podcast Stations" of your favorite shows (if you have any) to collect and manage a bunch of shows together. To set up Podcast Stations, select Podcasts in the iTunes library, click the My Stations tab and then click the Settings icon on the right side of the window.
Locking the Screen
On a Nexus 7
Q. I just got a new Google Nexus 7 tablet. How do I keep the screen from flipping around every time I move it? I can't find a switch on the side.
A. The new Nexus 7, a tablet by Asus running Google's Android 4.3 (Jelly Bean) software, can rotate its screen between portrait and landscape orientation based on the way the tablet is held. If you tend to move around, or shift frequently when reading, the screen may keep trying to reorient itself.
You can lock the orientation in either portrait or landscape mode by swiping down from the top right of the screen to get to the Quick Settings box. In addition to controls for brightness, Bluetooth, airplane mode and general settings, you should see an Auto Rotate icon. Tap it to lock the screen in the orientation you prefer.
TIP OF THE WEEK Hitting the Tab key to jump through fields in a Web form can speed things up because you do not have to use the mouse to click into each box before starting to type. For sites that use a pop-up menu to select an address's two-letter state abbreviation, most Web browsers still let you keep your hands on the keyboard. When you get to the state menu, type the first letter of your state to jump to that part of the alphabet; for example, if you live in New York, type "N." Doing so usually jumps the menu to Nebraska (or North Carolina, depending on the site), but keep hitting the N key until New York appears -- then tab onward to the ZIP code field. J. D. BIERSDORFER
