Cant change the viewport/screen back to normal size

[ZipMan 0]

I am running mac with a Swedish keyboard. By mistake i pressed the "+" button on my keyboard and the screen/viewport went very small. I am now unable to scale the screen back to max size, as a matter of fact i am not able to scale it back to any other size.

 

I did logon to a Windows system with Swedish keyboard and there it worked.

 

I also noticed that it was the "+" key that decreased the size. Nothing happens when i press the "-" key.

 

Can someone please advice me how to fix this problem?

PROBLEM FIXED

 

I changed the keyboard layout to English and then i could do it. However, it should probably be possible with another layout.
