Kim Komando answers your computer, camera questions

OSKALOOSA — Q. I’m suddenly getting questions from people on Facebook. How do I opt out?

A. You can’t. Facebook Questions is a new option for informal social polling. Creating a question is just like creating a status update. They are even in the same area of your Facebook profile. Just select the Questions option in the status update area and enter your question. You can add premade answers for your question. You can also let your friends provide answers. I would be careful when using the Questions feature. Make it something that actually matters. For example, it’s a good way to decide on meeting places and times. Businesses can also use it for customer feedback.

Q. I accidentally saved over an important file. Is there a way to recover a previous version? I use Windows 7.

A. You should be able to recover an older version of the file. All editions of Windows 7 have a feature called Shadow Copy. This creates periodic copies of files. Vista Business, Enterprise and Ultimate also have Shadow Copy. Right-click your file and select the Previous Versions option. You will see a list of previous versions of the file. However, it likely won’t include very recent changes. If you deleted the file, you obviously can’t right-click on it. In that case, open the folder that contained the file. Then, right-click a blank area. You'll see the Previous Versions option. This lets you access previous versions of the folder and files it contained.

Q. What does the VoiceOver feature in Apple’s OS X do?

A. VoiceOver is designed to help those with visual impairments. It reads out loud everything on the screen. You can also use it to communicate with Braille displays. To activate VoiceOver, just hold Command + F5. Pressing the Spacebar will activate a tutorial. One handy feature is QuickNav. This helps you navigate your Mac with the arrow keys. Each object you pass will be read out loud. To start QuickNav, hold the left and right arrow keys simultaneously. Now use the arrow keys to move. To click an object, hold the up and down arrow keys simultaneously.
