One would expcet it to be in View | Show/Hide but it is not.
The only way I have found is with VBA:
Application.DisplayStatusBar = False
In the Excel Options on the Popula tab, check the Display Developer on
Ribbon
Now you can open Developer and clcik Visal Basic
Copy the cose above into the Immediate window; tap Enter key
Done!
Of course, Application.DisplayStatusBar = True will restore it.
