Working on slides and view is now all magnified

[Guest]

Help, I'm working on a presentation, I have to finish in the next hour. I
hit some keys, which ones I don't know and now the view of the slide I'm
working on is magnified to a portion of the slide. I can't see the whole
slide to work on it. Help, I can't finish.

I found ZOOM and got back to normal size.
