Apple has updated iTunes U to version 2.0, with a bunch of new features for students and teachers. Students in private courses can now pose questions on the course, any post, or an assignment; and students in the same class can join the discussion to ask questions or provide answers. Teachers now have the option of creating or updating courses from their iPads and can use the iWork apps to create course materials. Students and teachers both can now receive push notifications for discussions. follow link
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.
