Most advanced page layout programs and word processing programs have a feature called smart quotations. This feature automatically inserts these marks into the text when the inch mark key is pressed. Too many hyphenated line breaks in a row creates unattractive text that is difficult to read. As a general rule, three hyphens in a row should be your maximum. Discretionary hyphens can be placed where you prefer a word to split.
Most computer programs provide for a discretionary hyphen.
While this may take a little extra time and effort, the payoff is the professional look your text can create. Use the right dashes and hyphens. A professional looking publication can be affected by the smallest detail. There is a difference between dashes and hyphens. Em dashes organize phrases and clauses within a sentence.
