In Windows XP, an en or em dash may be typed into most text areas
(including a Mozilla Firefox browser window to do a Google search, but not
SSH terminals!), by holding down the Alt key and pressing 0150 or 0151
respectively. The numbers must be typed on the numeric keypad with NumLock
turned on.
--------------
For wildcard searches, altavista is better, google doesn't do it (though it
now allows ~ to allow synonyms). Google also allow searches for
brownies (fudge OR fudgy)
--------------
AlltheWeb.com recommended by NYT 2003 for link searches.
link:URL will search for links to a particular URL. To search for web
sites that link to or even just mention a particular URL, type just the URL
without "link:".
--------------
filetype: will restrict search to particular file types (pdf, ppt,
etc.).
