return/enter key to open/launch files/apps
Hello
Just before I bought my new mac, I saw a genius at Apple Store open files/launch app with the return/enter key.
And I just forgot to ask him if it had to be configured/customized....
when I tried to do it with my mac, it did not work....
Do you guys know how to open files with the return key on Mountain Lion?
I just saw the guy doing it...
thanks
