Idiot that I am, I was playing around with system preferences. Now, when I try to use Quick Look, the space bar will open the item, but will not close it, unless I tab the focus to the red "X" button. What did I do, and how do I restore it back the initial setting?

So the answer was the Preferences -> Accessibility -> Keyboard. Once I deselected "Enable Full Keyboard Access", the Quick Look feature was restored and the annoying blue focus box went away. Thanks for helping.
Hi Mark Stokes,
Fascinating question! I have searched through settings looking for a way to change the spacebar functionality. I got nothing. No clue what to tell you on that one. You said "playing around with system preferences." Do you recall which preferences? I have looked around through Keyboard, etc. but find nothing.
Good question too. I was mostly in the keyboard and the accessibility panels. Am certain I clicked something but who knows what. Also getting that blue focus box around everything. Am sure is related.
"Also getting that blue focus box around everything."
I believe that is caused by turning this on. Bottom of System Preferences > Keyboard > Shortcuts.
For the other issue, you might try going to the Keyboard > Shortcuts, select each of the categories in turn, and click on the Resort Defaults button. You may have accidentally assigned the Spacebar to do something else. Although, odd it would open Quick Look, yet fail to them close it as well.
