I often start up an app to do something quickly, e.g. quicktime, record some audio, check it out, then I'll Q out of it.

I don't know about other people but generally for me Q means "be gone as fast as possible"

I always get prompted with these though:

Can I make the "Delete" or "Don't save"-type options the default?

So I can just hit enter when the dialogue appears and quit the app without saving any changes to that document?

Command Backspace (⌘⌫)

This works in all the apps I've tried (Preview, QuickTime, ScriptEditor):

  1. Q to ask to quit, then
  2. to quit without saving.

It seems selects the Don't Save equivalent in all these dialogues.


The options you want to make the default, are the options that are the most likely to cause data loss, and so they are not the default for a reason. However, you mentioned quitting using the Q key, so you’re not afraid to use keyboard shortcuts.

I mention this because the Mac OS usually allows you to select a button in a dialog by hitting and the first letter of the button’s text. In the ‘Delete’ or ‘Don’t save’ case, this would mean you can dismiss the dialog and not save by hitting D. For ‘Revert’, hit R.

It’s not as convenient as Q and Enter, but it’s still two keystrokes. And without opening you up to potential data loss by default.

    This didn't work for me in either of my examples (Preview nor QuickTime)

  • I am surprised - it works in the default File dialog boxes. I’ve been using these shortcuts for years Mar 24, 2018 at 14:17
  • DIdn't work in script editor either

    This doesn't work. In Preview, at least, where I tried it.

  • The default these days is Cmd/Backspace, though some apps still hang onto the old Cmd/D.
