You're looking for something on a long web page with Internet Explorer or Netscape. You think it's there, but you're faced with seemingly insurmountable number of paragraphs, sentences, and words to hunt though.
Well, next time this happens to you, hit the Edit menu, Find (or CTRL-F for you shortcut lovers). You'll get a handy little "find" box that lets you type in a specific word. After you type in your search term, hit the Find Next button and Explorer will look for that word on the page. If it's successful, you'll be zapped right to it.
As if that wasn't cool enough, you can also use a variation of this tip in Windows Explorer. Next time you're looking for a file in Explorer, hit CRTL-F and you'll get a Find or Search box (depending on what flavor of Windows you're using).
If you are already in the area of your hard drive where you think the file is (say, My Documents), hit CTRL-F and your search will be set to look in the My Documents sfolder.
