Windows to Mac Shortcuts

First week into using Mac for the first time (WHEW). I work a lot with MS Office programs and use the shortcuts for cut, paste, copy, print and such in my work.

I have figured out that the “command” key functions the same as the Windows “ctrl” for those shortcuts; I also figured out how the Home/End works using “command” with the right/left arrow keys. What I cannot figure out is the Page Up/Page Down sequence.

Is there an article which outlines/shows the shortcuts which emulate the Windows shortcuts? 

Thanks.
