To find out and learn the keyboard shortcuts it would be nice to see them next to all menu entries, e.g. to rotate, or zoom.
With the zoom especially there is no entry for “zoom in … a” or zoom out … z” so this should be considered to add.
Not sure if I’d ever pull down and select e.g. 2000% in one jump from the menu ???
Brand new interactions and interfaces. 
Easy to use and quick to get started.
