After some good direction from Calvin and Tracy, I was able to get this mapkey to work.
Some lessons learned:
* Use the pause function carefully and at the correct time.
* Use the pause for keyboard option.
* Don't try to create a text style and then use it later in the mapkey. Pro/E aka Creo refers to text styles by number and different drawings will have different numbers and you will get unexpected results. It's better to just change the text style values directly. (text height, justification, etc...)
Thanks for all the help, everyone.
