[ Security ] Open Question : How do I open up the Internet?

I have an iMac Desktop. And I'm playing this game right... And usually. On my previous computers.... I could just press like.. The option button and it GAVE me the option to Click on the Internet. But not the iMacs keyboard. I press option. Nothing happens. I press the Esc button nothing happens. It's like the screen is locked on the game screen. Of course I can log off but I don't want to. I have no idea how to access the internet. Not even Alt - Control Delete works. Not that it's frozen. But I just wanna see if there's any option to let me access the internet. Can anyone help me?
