In using Dictation in iMac, is there a Glossary of terms?

I am using dictation in English in iMac, but there are terms, words, and symbols that I do not know how to pronounce in a way that iMac can type them appropriately. For example, quotes: ".zxcv", words in italics,or in bold, etc. So is there a glossary that I can look into for ways how to pronounce what I want iMac to type? This would be similar to the ASCII Extended Character for Set for Mac, but "in reverse": i.e., tell me how to pronounce the term for iMac to type.

This would save me lots of time. as it is I keep on "Speaking" and then have yo go back and go thru a tedious process of looking at the type word, then checking with the 'written word original", the correct, then lose my point of reference in either text, aaaagggghhhh!

Ideas are most welcome!
