Some useful tips from David Pogue in his New York Times "Circuits" column:
* Nobody, but nobody, is going to give you half of $80 million to help them liberate the funds of a deceased millionaire…from Nigeria or anywhere else.
* You can enlarge the text on any Web page. In Windows, press Ctrl and the plus or minus keys (for bigger or smaller fonts); on the Mac, it's the Command key and plus or minus.
* You can also enlarge the entire Web page or document by pressing the Control key as you turn the wheel on top of your mouse. On the Mac, this enlarges the entire screen image.
* On most cellphones, press the Send key to open up a list of recent calls. Instead of manually dialing, you can return a call by highlighting one of these calls and pressing Send again.
* You can tap the Space bar to scroll down on a Web page one screenful. Add the Shift key to scroll back up.
* When you're filling in the boxes on a Web page (like City, State, Zip), you can press the Tab key to jump from box to box, rather than clicking. Add the Shift key to jump through the boxes backwards.
* You can adjust the size and position of any window on your computer. Drag the top strip to move it; drag the lower-right corner (Mac) or any edge (Windows) to resize it.
* When you're searching for something on the Web using, say, Google, put quotes around phrases that must be searched together. For example, if you put quotes around "electric curtains," Google won't waste your time finding one set of Web pages containing the word "electric" and another set containing the word "curtains."
* You can use Google to do math for you. Just type the equation, like 23*7+15/3=, and hit Enter.
* Oh, yeah: on the computer, * means "times" and / means "divided by."
* Google is also a units-of-measurement and currency converter. Type "teaspoons in 1.3 gallons," for example, or "euros in 17 dollars." Click Search to see the answer.
* You can switch from one open program to the next by pressing Alt+Tab (Windows) or Command-Tab (Mac).
* Just putting something into the Trash or the Recycle Bin doesn't actually delete it. You then have to *empty* the Trash or Recycle Bin. (Once a year, I hear about somebody whose hard drive is full, despite having practically no files. It's because over the years, they've put 79 gigabytes' worth of stuff in the Recycle Bin and never emptied it.
* You don't have to type "http://www.blogger.com/" into your Web browser. Just type the remainder: "nytimes.com" or "dilbert.com," for example. (In the Safari browser, you can even leave off the ".com" part.)
* Come up with an automated backup system for your computer. There's no misery quite like the sick feeling of having lost chunks of your life because you didn't have a safety copy.
