I accidentally unchecked View -> Show Menubar which hides the menubar in File Manager, and there doesn't appear to be a keyboard shortcut to show the menubar again.
How can I go back and make it appear?
I had a look on Thunar (default file-manager on XFCE) and it reports ^M (ctrl+M) will display/hide the menu bar.
I had it visible so could look thru my menus, but if I didn't I'd have tried to hit ALT+V in hopes it'd show the VIEW menu (or ALT+F to show FILE menu). It won't work in every program, desktop or place, but works for many.
