I'm in singularity and I accidentally pressed a key combination that made my viewer super magnified?

Help! This has happened before and I even re logged and it goes right back to this super close-up view! I can't function!!

You may have pressed CTRL+0 which progressively magnifies the view with each key press and perists across logins. Press CTRL+ 9 to instantly go back to normal view. CTRL + 8 will progressively reduce magnification with each key press. I can't think of any other key combination that would increase viewer magnification.
