I've spent one and a half day trying to get OO to open the

So, how do I open to the next one-page-at-a-time?
Thank you! Someday maybe I can help others.
Are you intending to build a book of scanned page images, that is, an exact copy of an existing book? And then, from this collection of images, you intend to make a .pdf file, so that you effectively have a .pdf copy of the original book?If I understand you correctly I cannot insert a scanned document - and build each page in OOo one-at-a-time - one scanned document per page (I'm scanning 8 of my books to convert to pdf to put on my website for teachers, counselors, etc.)
"Enter" is "Return" on some Apple keyboards.I have a "control" but I do not have an "enter".
On a Mac use "Command/Return".I work with a MacIntosh (10.5 Intel) I looked an looked and hit every button I could find - I have a "control" but I do not have an "enter". So I pushed "control" and hit every button on the keyboard (and on my coffee-maker) and could not get the page to turn.
