I don't usually use the KJV or NKJV, but I am aware that some of my listeners do. So I created a visual filter for the NKJV that will alert me at a glance that they will be seeing something different than what I am quoting or reading, because of Greek text differences between the Textus Receptus and NA27/UBS4. The screenshot shows that I did a footnote search within the NKJV (I didn't hit enter on the search because it would color my visual filter in NKJV.) The highlight uses "Text Before" under "Label Text". I created a separate palette so that I could turn the filter off or on and arrow up or down to find the next filter highlight, if so needed. The highlight occurs immediately in front of the numbered footnote hyperlink throughout the N.T. (For those who don't normally pay any attention to Greek apparatus, the NU in the footnote is an abbreviation of the Greek Texts NA27 and UBS4 and the M stands for the Majority Text.) You could leave the M out of the search if your not interested in that.
