How do you insert a non breaking hyphen in a document?

A non-breaking hyphen is when you want two Words to appear together on one line and not split over two lines. Once there is not enough space at the end of the line for the two Words, both will be brought onto a new line, rather than having one on at the end of one line and the other at the start of the next line. So the two Words and their hyphen are always kept as a single entity, and is therefore non-breaking. A non-breaking space works in the same way, always keeping two Words that have a space between them on one line, like the name of a company.
