A family of Microsoft word processing software products for creating web, email, and print documents.
Extending on Daniel's reply:
Pages do not exist in the structure of a Word document. Out of necessity, the term page is used in a strictly conceptual frame of reference. Microsoft has gone to a great deal of trouble & expense to make it appear otherwise because that's what users want to see.
What he described will copy the objects [text boxes, images, shapes] displayed on the representative Content 'page' along with their formatting. However, none of the elements that are on the Master Page on which that page is based [Headers, Footers, page numbers, background graphics, etc.] will be included. Master Page content will have to be copied separately & pasted to a Master Page in the other document.
