Tab key not working properly in dialogue boxes in macOS I change the setting ‘Full Keyboard Access’ (the Keyboard settings in the ‘Keyboard Shortcuts’ tab) from ‘Text Boxes and Lists Only’ to ‘All controls’. Now, I am able to press Tab to moving focus, as illustrated below.



When I hit Enter, pop up a window, instead close the window.

My desired action: hit Enter → move to ‘Don't Save’ → Enter → Close the window.
Hitting Return will activate the default command (the blue button). Pressing the space bar will activate the selected command (blue ring around it).
