I am cutting and pasting highlighted segments of text from an Adobe pdf format document which is in double columns, to a new blank word document. When I paste the text into the document it aligns left (default) but the text only goes about one half to two thirds of the way across the page. I desire the word document to only have one large column. Without manually removing the “enter” key codes, how can I reformat that text (or prepare the blank word document) to have the text behave as if it were always one single full page column? (I am using Word 2003, Windows XP)
