However Opera’s still has that ace up its sleeve. By typing a ‘g’ in front of the search you will search Google. So “g osGuide.net” will search Google for “osguide.net”. I can’t begin to tell you how useful this is. This would be pretty weak if you couldn’t search other search engines as well, but of course you can, by default you can search:

• g – google
• y – yahoo
• a – ask
• z – amazon
• w – wikipedia
• e – ebay
• s – yahoo shopping
• b – bitTorrent
• h – browsing history

You can also add any other search engine you like. Just go to Tools > Preferences > Search and you can view all of these default search engines as well as add any you like or change the key used for these search engines. The second is the classic quick search bar which is located next to your address bar. This style of searching is similar to that of IE, FF, and Safari. It also basically works in the same fashion as the other browsers however it allows you to choose from the same 9 different search engines by default. The third search style is Opera’s speed dial. A great search location because its on every new tab you open. By default it searches Ask.com, but it can easily be changed to any that you like. To do this Right click on the Search bar > Manage Search Engines > Click on the search engine > Details > check use as speed dial default and you can set it as your overall default search as well.

Personally with only the address bar I have all the searching power I could ever want. I can quickly search Google or turn around and quickly search Wikipedia without changing any settings.
