I have a very long document that many lines can be logically grouped into ranges. For example, maybe something like this:
cow #1 cow #2 cow #3 ... dog #1 dog #2 ... table #1 ... chair #1 ... etc.
This list can be grouped into ranges (lines 1-1000: animals, lines 1001-2042: furniture, etc.) and sub ranges (lines 1-444: cows, lines 445-678: dogs, etc.)
Since this is a long list, I want to present a quick document map type of scroll bar thing with colored areas (don't need labels) to allow quick navigation by clicking the bar. Any ideas/examples of how to do this?
Bonus What if the ranges aren't nested, so that we can have for example ranges such as 1-200, 100-150, 120-300?
