When programming the X52, when you right lick on a button--say the pinkie button--you can choose to have the button "latched".
What does that mean? I am guessing that it means when you push the button its state becomes "on" until you push the button agin and it then becomes "off". However, I can't see any functional difference in having the button set as 'latched' and there is no documentation as to this option.
