Thanks for trying to help out. I read your reply all the while still thinking about what was written in the book, and what you said makes sense. But, I'm having some difficulty trying to understand what the book is saying now. I had thought that in Step 3, when the Command-Z is pressed to undo the rotation that it would undo the change. In fact, the Properties Inspector numbers were white but the Record Button was red - just the button, not the area in the button square surrounding the button. Elsewhere/somewhere, I saw that the entire square around the button would turn red.
Since there has been an update to "5" since the book was written one thought was the red square was changed to turn red.
Anyway, I can't do anymore on this for the time being as there are other thing I have to work on so I'll have to revisit this later. I hate doing any steps beyond what I know is "perfect" because I don't want to get off course with the book. There are a few other things in my life besides studying the Motion 5 book. Not a whole lot, but enough.
Side note: After my original post I discovered a few things to edit but couldn't get the site to allow me to edit. For one thing, it isn't "Chapter 4", for anyone reading the book it's "LESSON 4". Don't want to confuse anyone who comes by later.
