Adding Strafing to 3rd Person Controller

Hello there, I'm not new to Unity but am quite new to coding in any capacity. So far I've got a great 3rd Person Controller running quite well but my only problem is adding strafing to the code to allow strafing on Q and E keys, or alternatively on the A and D key at another time.

I'm using the stock 3rd Person Controller script from Unity's Standard Assets and for the life of me, after trial and error, after going back and forth on every forum, hub, or resource and finding very little if any detailed help on getting this small task completed.

MY QUESTION: How can I get the player to strafe left and right instead of turning left and right?

Here is a web player of my current controller build. It still needs work so bare with it, but it does work outside of the strafe. http://mediarotation.com/controller/ And here is the code provided by Unity within the Standard Assets/Controller/~

Thank you so much in advance for any help that can be provided.
