I tired a quick search but my eyes dont have it in me....Is there a way to do point selection by "1 over n"...To type a value and have a curves points selected by every other 2nd, 3rd 4th etc????

Actually just found a wishlist from 2007 where a guy asks about it... The thread is like 100+ pages long!!! LOL
