Hi. Using Word 2003 on Win XP Home

Please excuse this newbie question but I must create
a long (60-80 pages) MS Word 2003 document and
the manual effort (Insert Break New Page Okay)
involved in inserting many new pages in the document is
getting to me.

Don't know how to go about finding a Word command
key to eliminate this drudgery. Please advise. Thank you.
