To the author: stop railing about toolbars. Misguided as Microsoft is in many cases, they do have metrics for those things and people do press them. I can also add a ton of anecdotal evidence pointing that even super smart casual users don't know or use keyboard shortcuts. Even for copy paste, in many cases.
Sad from our point of view, but a lot of people have better things to do with their lives and we should stop judging them.
I like toolbars for quick, frequent-but-not-that-much actions, like exporting to a pdf in LibreOffice.
But I also like menu bars, as those give you some shortcuts if you often use a functionality. As an example, and since I type this into Firefox right now, after glancing at the menus, Alt+V,Y,N disables the page stylesheets, Alt+T,S synchronizes the account, etc.
