Thanks to all who replied. After examining the many responses that included the mapkey definition that worked for them, I see that the `ProCmdModelSave.file` that was near the end of my mapkey appears the be the problem. Several responses suggested that I start with a fresh record from within Pro. I did that and the mapkey definition did not have the `ProCmdModelSave.file` command in it and it worked. Don't know how I picked that up in my original but at least the mapkey is working now.
