These Bookmarklets use the Google search engine, and a few others, to search for stuff. Including to search for MS Knowledge Base articles, or all the MS sites (because Google is often quicker than Microsoft's own).
N.B. some are adapted (and slightly improved because mine for the KB search restricts itself to the .support.microsoft.com site which houses the KB articles) from the cool tips given in the LangaList newsletter. Some are updated for better cross-browser support using Jesse Ruderman's terrific coding.
If you're not sure what a Bookmarklet is, please take a trip to The Bookmarklets site or Jesse Ruderman's site : you won't be sorry!
These should work for Internet Explorer 4 and above, and recent versions of Mozilla, Firefox, Netscape, and Opera, but you'll need javascript to be enabled (at least in whichever Security Zone you put this page[1]).
You can try each Bookmarklet first from here if you like: just left-click the links and and enter search word(s) in the dialog box that pops up. Or highlight (select) a word on this page first and then left-click the links (select+click won't work from here in Opera, but it will once you've added them to your Bookmarks or Personal Bar).
Then to save each Bookmarklet, right-click (or drag and drop[2]) and add it to your Favorites or Bookmarks (or Links or Personal Bar or Taskbar Toolbar or … ).
To use each Bookmarklet, left-click the Favorite/Bookmark and enter the search word(s) in the dialog box that pops up. Or most will search on any word(s) you've already selected on a web page.
