@ symbol in Finnish keyboard?

Hi,

I just got my hands to second hand MacBook Pro 15" Retina from mid 2012. It has a Finnish keyboard layout. Previous owner has some weird settings and I can't access @-symbol which is located in key 2 in Finnish keyboard.

Alt+2 gives me ™ symboll, while Cmd+2 swaps the focus to the tab.

How do I get access to @-symbol?
