Exit the "Do you want to save your changes?" dialogue as fast as possible (discard changes) When I press cmd-q or cmd-w on an app, sometimes I get a popup like:



I just want to quit the app as fast as possible, I want to select the "Revert Changes" or "Don't Save" etc. equivalents without having to move my hand to my mouse/trackpad, move the mouse cursor to the button on the screen, and click.

I don't want to have to take my hands off of the keyboard.

cmd-backspace used to work for me

But it doesn't anymore, at least not in Preview.app.

What's the new solution in Catalina?
Press the Spacebar.

⌘ + Backspace works if you are trying to choose “Don’t Save” but the Spacebar is what you want to select ‘Revert’.
