FAQ - difference between "Copy" and "Add to Copied Text"?
Answer:
"Copy" - Only the text of the verse being pressed is copied.
"Added to Copied Text" - The text of the verse being pressed is copied and added to the end of the existing copied text. There is a practical reason for this design. For example, if you want to copy John 3:16, 18, 20. "Copy" John 3:16, then "Add to Copied Text" on John 3:18 and 3:20.
