Shortcut to exit 'Customize' state

I run DO full screen most of the time. I know about the Alt-click on a button to go directly to editing but is there a way, once edits are OK'd, to gracefully exit the customize state without hunting for the dialog box, which is in the background?

Don't you have this button in your top right corner?

Wow. Add that one to the 'blind as a bat' category. :grinning_face:

Thank you.
