Here's what I did:

From within MOHAA I assigned the Backspace key to the Voice Message: Main command. From there you can go thru the voice messages using the number keys. It's similar to what you posted.

Example:
Backspace 41 = "Is that all you've got?"

The Voice Message menu is three menus deep. Backspace brings up the main menu, 4 brings up the Taunt submenu and 1 selects the specific taunt. You've seen the menus pop up in the middle left of your screen, right?

I jumped into an empty server and typed up the list of messages so all I have to do is look on the list, find the message I want and hit Backspace ##.
