OK? XX? Difference
 

Is there any difference between OK and XX in setup. My guess is OK is save current, XX skip.:confused:

Basically.

If you select "OK", it will save that value and go to the next value.

If you hit xx it is the same as "Cancel", except there wasn't enough real estate to print out the word "Cancel", it ignores any changes to that value and goes to the next value. Useful if you "fat finger" something and didn't really mean to change it.
