Editing tip: Ensuring all quotation marks are in your manuscript. However, this only works in specific circumstances and may not apply to you. Please be certain of your style of writing to see if it would apply.

NOTE: It was noted by Hitch on MobileRead forums:
What happens when you have a character using multiple paragraphs, for his dialogue? In that instance, you would always have more opening quotation marks then closing--and it would be easy to have an odd number.
In this instance, it is true that my double tap method below will not work. I suppose I may be unusual in that I never allow my characters to have dialogue in two paragraphs. I always intersperse actions and counter dialogue between. If you write otherwise, than please do not use the method listed below.
