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’.
