I said- this is the one thing I was waiting for and requesting it for years. If they included it in a list of new features, it would save me from a stress of transition to the new purchasing system. lol.

Like here?  :) We're glad you found one feature that made it worth it!

...and this is how it works. At first, the request seemed silly - there's a keyboard command. After she explained how she works, it make a lot more sense...AGO keyboard remote from the computer, with a wireless mouse. Of course! An undo  button would be helpful under those circumstances.
 
And the mighty Cakewalk said, "Behold! For there is now a button you can access from your wireless mouse! Go forth and undo!" And undo was done.
