Hi, I too, sometimes, I've removed my toolbar. Later when I wanted to restore it, I've never succeded. The more simple is maybe to download it one more time. If there is an other way, I would be happy to learn how to do.
I accidentally got the menu and from view permanently enabled them. You are right ye.zero it does show up when you hold Alt but I have to try 4 times to understand how it shows up.
