eFor context, see the thread here:
As I read through the Bible in Greek, I would like to prepare to read a chapter by reviewing the rare words in that chapter before I read it. I would like a list of the words in that chapter, sorted by frequency in the entire New Testament. Unfortunately, there is no way to do that currently. The best way is to create a word list for a particular chapter, and Merge (Intersect) with a word list of all the lemmas in the New Testament. However, this combines frequency counts, so it makes the resulting frequency counts inaccurate. As an example, if there is a word that's used only 4 times in the New Testament but they all happen to be in this chapter, the frequency count would be 8, but if there is another word that is used 4 times in the New Testament but only once in this chapter, the frequency count would be 5.
My suggestion is to add another option to "Filter" by reference, selected text, another word list, or clipboard, and the ability to clear the filter.
