MBP 13" display problem - please help

I was working on my MBP and my 2 year old son executed a sneak attack from my left and hit some keys that made the display go funky. It's almost like everything is on a larger display now... so I have to scroll up and down and left and right on everything. I can't get the windows to automatically size correctly. The dock is off the bottom of the screen (and no, it's not on auto-hide) and I have to scroll to get to it. If I can see the dock, I can't see the menu bar. I also have to scroll to the right if I want to see the scroll bar and whatnot. Like on the Mac Rumors site, if I want to see the tab that says "Forums," I have to scroll to the right.

I have tried adjusting the display resolution - no help. I've rebooted a few times with no results. I've googled everything I can think of and haven't come up with good ideas about what the problem might be and I didn't find anything on the Apple site, either.

I am sure that my son hit some crazy keyboard shortcut that just needs to be undone, but I have no idea what exactly that might be.

Any ideas???? I welcome any suggestions! Thank you.

 

Yes! I was able to fix it through Universal Access. Thank you!!!

That's one of the few System Preferences panel screens I hadn't looked into. I'm a pretty recent convert from Windows and sometimes I still don't know where to find some things.

Thanks again
