after playing around some time, I added a previous, next and home button
for faster frame distance zapping.
With these buttons, I can narrow down (previous/shorter distances) the
cutting point and switch to larger distance (home) zapping very fast.
I use the next button (larger distances) very seldom and added it for
completeness only.
You can switch the previous and next meaning, when you order the list to
ascending distances.
Regards, Olaf
