Go to the "Annotation" section under Commands and you will find it there, not under "View". The help documents that it is available on the Annotation toolbar in the following two topics:
It is one of those commands that relates both to annotations and viewing and we can only have it present on the definition of one toolbar category so we chose Annotations since it is strictly about annotations and not general viewing.
I hope this helps,
Thanks! There it is!
I use this tool with mouse gestures. I have not noticed that it is not in the view catorgory on the commands tab but it is available if you add it to mouse gesture.
