People used to using Other Browser(tm) might have been missing the possibility of being automatically redirected to a search engine if they type in an non-existent address in the address bar.
Some browsers, including Opera allows you to automatically add a prefix and postfix so that say 'foo' becomes 'www.foo.com', but it normally stops there.
Fear not. A user actually asked for this feature in one of the IRC chat channels at http://my.opera.com/chat/
User-what? You might ask. Well, it just happens to be that Opera lets you run your own scripts on virtually any page out there. You put a script in a dedicated drawer and you tell Opera to look there when loading pages. The script might be run before a page loads or after it is finished, depending on elements found in the page, the domain of the page or other criteria.
and download the auto-search-forwarder
script, put it in a directory of your choice and go into:
When typing addresses that don't exist in the address bar, you will now get redirected to Google's Feeling Lucky feature. That is namely the first hit searching on the term you typed.
Unfortunately any spaces you might have typed disappear, but you can circumvent that by using underscore, this means if you want to search for "foo bar", use "foo_bar".
