Apple’s HIG documentation clarifies how such a situation should be handled: see https://goo.gl/AwhKiW. Quoting the relevant paragraph: "Don’t use a default button if you use the Return key in the dialog’s text fields. Having two behaviors for one key can confuse users and make the interface less predictable. Also, users might press Return one too many times and dismiss the dialog (and activate the default button) without meaning to.” Beyond that and in reference to the entire discussion, I would suggest that JavaFX follow the platform behavior as closely as possible. But in complex dialogs in which the user is presented with controls which respond to the “Enter/Return” key, it is probably up to the programmer to be aware of the guidelines, and make the necessary adjustment by making sure that none of the buttons in the button bar are set to “default button”. As noted, OS X configures the key press triggers for actions of the default (“Return”) and focused button (space) differently. Whether *all* users are aware of, or understand, this is probably not the point. For those who do know how Apple prescribes how dialog buttons should work, it has become ingrained behavior to hit the spacebar to fire the focused button. However, note that the ability to have a focused button other than the default depends on the user having activated “Full Keyboard Access — All controls” in the Accessibility preferences. Only then can one can navigate through the dialog controls to focus a non-default button, such as “Don’t Save” in TextWrangler. My guess is that few Mac users, other than programmers, have enabled this functionality. (It may be too much to ask — or impossible — to have JavaFX respect the accessibility settings: that is, not allow tabbed navigation across the buttons if the “All controls” setting is not in force.) [I haven’t used Windows in a very long time, so I cannot comment on how it, across its many versions, prescribes how dialog buttons should work.]
