By recording and processing the direction of light rays entering its sensor, the forthcoming Lytro camera promises to provide previously impossible features, such as the capability to focus on any part of a photo, at any time, or even bring an entire photo into focus at once. The camera isn’t slated for release until later in 2011, but you can play with refocusing photos and read more about the technology on Lytro’s site now (the picture gallery requires Flash on a Mac, but does work in iOS via HTML5). follow link
Delete All Comments in Word in a Flash
You needn't clear comments in a Word document one by one. Instead, bring out the big guns to delete all of them at once:
1. Chose Tools > Keyboard Shortcuts.
2. Under Categories, select Tools.
3. Under Commands, select DeleteAllCommentsInDoc.
4. With the insertion point in the "Press new keyboard shortcut" field, press keys to create a keyboard shortcut. (I use Control-7)
5. Click the Assign button.
6. Click OK.
You can now press your keyboard shortcut to zap out the comments.
The steps above work in Word 2008; they likely work nearly as described in older versions of Word.
Lytro Promises to Revolutionize Photography
Otherwise, you'll be left scratching your head for a while - like I was - wondering what the fuss is all about. :-)
