Defaults tool equivalent of Ctrl-F7 In OSX one can use Ctrl-F7 to change what the Tab key can move the focus between. By default it is only text boxes and lists but after pressing ctrl-f7 one can move between all ui elements. 

I was wondering if there is a way to toggle this functionality by using the defaults tool.
After some searching the equivalent command using the defaults tool is 

defaults write NSGlobalDomain AppleKeyboardUIMode -int 2


Anyone can verify this by toggling the values and then reading the key value. The default value has a value of 0 and switching it to all ui elements will turn it to a value of 2.
