I’ve been always annoyed with inability of selecting dialog box on Mac using keyboard like you can in Windows:
Thanks to this rather-old-post there’s actually a way to enable dialog box option selection / cycling using keyboard. Go to System Preferences -> Keyboard and select All Controls under Full Keyboard Access at the bottom:
Keep in mind Return key will always activates the blue button regardless which button has focus. If you want to active the button that has focus (blue border), use spacebar.
Now there’s one less thing for which you shouldn’t take your fingers off keyboard from.
Only thing that’s still annoying – ‘return’ keydown != ‘spacebar’ keydown
Yes you’re right! I remember struggling with this when first switching from Windows to Mac. Basically return always triggers the blue button while space will trigger whichever other button that has focus (blue border)
