This may not matter for the newer versions of Dragon. Sometimes when you want to put one letter into a sentence, such as A, it works better if you use the phonetic alphabet. For instance if you want a capital A, I would say " press capital a" Lo and behold you have your letter. It also works really well in "spell this" most of the time I spell words out using the phonetic alphabet, rather than just saying the letters.

Just a quick tip for those of you who didn't know that.
