Seeing as there is no tooltip itself to tell you what each option does I have no idea what this option does, but when I scroll through to change it it seems to have no value until about halfway which says 1.. Idk if this is a visual bug or its meant to be like that (though it would make more sense to have a value at every line).
Screenshot to see what I'm talking about:

As you can see the other one has 31 while the Tooltip Delay has 0 yet it isn't set to 0 (all the way on the left)
