Style guides like those published by the Modern Language Association (MLA) and the American Psychological Association (APA) are great sources to turn to when you need to know how to punctuate something properly for a paper. But if you’re not writing an academic paper or your writing includes topics that aren’t typically found in professional publications, they won’t provide you with the answers you need. For those issues, you have to rely on your own judgment in applying the rules because an official standard hasn’t been set.
The ellipsis should be regarded as one unit and should not be broken at the end of a line. Toward that end, it is useful to know the code that will create an unbroken and unbreakable ellipsis for you on the word-processing program you are using. On most machines, it's a simple matter of holding down the option key and hitting the semicolon, but this varies from program to program. To avoid problems when you reformat a paper (change margins, font sizes, etc.), the spaces that surround the ellipsis should also be created as "non-breaking spaces."
