Rogue Amoeba has released Airfoil 4.7.4, which now provides support for Airfoil Speakers for Android (which was recently released as a public beta). The network audio streaming app also improves support for audio sent from an Apple TV (running iOS 5.1 or later) to Airfoil Speakers and fixes a crash that occurred when selecting "Show Airfoil Only in the Menu Bar" in Preferences. ($25 new with a 15-percent discount for TidBITS members, free update, 9.1 MB, release notes)
Close Word Comments Easily
If you don't like how precisely you must mouse in Microsoft Word 2008 to delete comment balloons, note that you can Control-click (right-click) a balloon to pop up a contextual menu. From the menu choose Delete Comment, and you're done.
Also, to get rid of all comments at once, choose Tools > Customize Keyboard and set up a keyboard shortcut to go with the DeleteAllComments command, available in the Tools category. Oddly, there's no Delete Comment keyboard customization option that I can find.
