Select the objects and press (Ctrl + L). To unlock (Ctrl + M)
reference : MMM 15, but I guess it will work with other issue.

Thanks so much for your thoughtful answer and for taking the time. To my knowledge, CTRL-L groups the items together but the individual objects still retain their properties. I am trying to make many objects into a whole object (in my case, I am trying to fade in across the whole object groups). Any ideas there?
You have posted to a thread which is more than seven years old and refers to a very old version of MM.
I strongly suggest you start a new thread with your question, making sure to include all the information in this post, especially about your computer and precisely which version and variant of MM you are running.
