Now there's a set of free plug-ins integrating the LSL Wiki right to your browser! With them you can configure LSL Wiki as your browser's search engine, such as for IE 7:
-- LSL Wiki Search on IE7
What's even cooler, on Firefox 2 the plugins feature LSL auto-completion!! Start typing in any function name to the search box (such as "llSetT"

-- Firefox 2 auto-completion example
And that's not all: the plug-ins are mirror-aware. That's right, if the main LSL Wiki is unavailable for any reason, your searches are automatically sent to the mirror site! In some cases it will even rewrite your queries "behind the scenes" so it's mirror-compatible.
On Firefox you can also configure the search into the main location bar (though you don't get the auto-complete benefit that way.) With minor changes the Firefox 1 plugin can also be used with the Mac's OS X Sherlock, however I don't have a Mac so have not tested this aspect yet.
There is also a Google shortcut if you decide to use the tool as the default search provider.
To get started please visit the LSL Wiki Search page. I hope you will find it useful.
All thanks go to Catherine Omega and Thraxis Epsilon for maintaining the wiki and its mirror.

ps. If you maintain an up-to-date LSL wiki mirror and would like it to be added to the search tool please let me know.
