In e-sword, I have downloaded the "Greek New Testament (Interlinear) w/Strong's Numbers". Some of the words are gray and have either "τσβ", "να", "σ" or "ναβτ" in red under them. What does this signify? I believe that it means that this word is missing from the Westcott-Hort version or missing from the Textus Receptus version. Is that right? I have posted an image of this along with this post.
In the image, I have shown "Parallel" view and shown the 4 views: KJV, Greek NT Textus Receptus, Greek NT Westcott Hort, Greek NT Interlinear +.
I have circled τσβ, να, σ, ναβτ below the gray words in question.
Do modules ever come with "Readme.txt" descriptions? Where would they be?
