Safari 6, how to automatically add ''.com''

Before upgrading to Safari 6, if i wanted to go to a particular site, all i had to write was the ''main'' adress without the ''www.'' and the ''.com'' for example, i only had to write OWC, it would add AUTOMATICALLY the www and the .com and go to www.owc.com. IT WASN'T GOING ON GOOGLE TO DO A SEARCH. Now if i only write OWC, it'll do a google search. is there a keyboard command to add automatically the ''www.'' and ''.com'' like on PC it was, ''CTRL+Return'' OR a Safari EXTENSION to bring that feature back.

thanks
