Retrieving a document

[Cubbie23]

I accidentally pressed a wrong key on my keyboard which brought up a completely different page. Tried to get back to where I was on my document and even tried "Undo" but it seems everything is lost. I s there still an easy way that "Word Dummy" like me can retrieve my document?

"Undo" will undo your last typing / deletion / move around. it will not undo moving around the document.
