Fix URL hint numbering
The previous behavior was actually the intended one, the URL hints are intended to strictly increase from start to finish (physically on the keyboard).
It might not be "technically" correct, but that's the original behavior before the refactor (and I think it makes the most sense, that's why I implemented it that way originally).
Also fixes activating the first URL, activating 0 didn't work.
