Tabbing to All Controls

Having just re-installed OS X there were some settings I was accustomed to that I had to find and reset. The hardest for me to find was the ability to tab to controls other than text boxes and lists. I remember this was an OS X settings I turned on a long time ago, I was very used to it but couldn’t find the dang thing. I was getting quite frustrated without it. Finally I found it, it’s under System Prefs > Keyboard Shortcuts > at the bottom. Enjoy.
