In the above online help page, for ArcGIS Pro, it would be helpful if it explained what the "other tools specific to a map view" are.
This stems from the fact I found I was unable to switch on the Maplex labelling engine when creating a map. There was nothing to tell me in the online help as to what I was doing wrong. The online help just said I could switch to the Maplex labelling engine.
Turns out I needed to have the map view enabled. This was far from obvious to me. After contacting UK Technical support they suggested I log this as an ArcGIS Idea.
Hopefully enough people will agree with me and ESRI will implement this.
