Q:

control + enter in browser takes only .com?

I have this strange problem, how exactly does control + enter decides the domain of a website??
If i type stackoverflow,then hit control+enter, it works and takes to homepage, but i type ubuntuforums, 
then hit control + enter, it does not recognise its ubuntuforums.org, but goes to ubuntuforums.com??
How does this exactly work? If i need to change this behaviour, how should i do it?

A:

It just take what all you typed in the address bar, append it with .com and start talking to that server.
If you want to visit .net user shift + enter
If you want to visit .org user control + shift + enter
