Modifying the search engines in Google Chrome

I'd like to change the default google search from Chrome to

http://www.google.ro/search?q=${search}&esrch=BetaShortcuts

the reason being the the localised version of the search engine does not apply the keyboard shortcuts experiment.

How can I change the search engine settings in Chrome?

Just go to the preferences menu -> Basics, and next to default search there is a manage button.

In the resulting popup add a search engine, come up with a name, keyword, and for the URL just use http://www.google.ro/search?q=%s&esrch=BetaShortcuts. This should work.

I'm on OS X so the steps may be a little different but it should be the same on linux and windows.

When you're done with that click on the new option you've created and press "Make Default".
