Automatic button highlighting/selection
Somehow I turned on a system-wide feature(?) that I'd like to turn off. A button or control of any dialog box is always selected (highlighted by a blue border). This happens in Finder or any app. See the "About This Mac" dialog image attached, where "System Report..." has the blue border. I've looked at at every system setting I can think of (especially Trackpad, Keyboard, Accessibility) to disable this, but no luck. Anyone know how to toggle this off?
