Four text editions are included in full in this program:
TR - the Textus Receptus, which is the oldest text edition and has served longest compared to other text editions
H-F - the Majority Text of Hodges and Farstad
N25 - the 25th edition of Nestle-Aland
N27 - the 27th edition of Nestle-Aland
However, in comparing editions, some differences disregarded.
Using the manuscript information and these editions, one can easily identify the text lore through the ages follow.
In the toolbar above the Greek text window, you can choose which of these four editions you want to see the text from (in the example above, it is the TR).
In case there are deviations from other text editions, at the bottom of the verse is indicated by which editions and possibly manuscripts the text of the particular edition is supported and which Bible translation follow that text.
All four text editions feature transliteration and translation. If one wants to omit these, and thus see only the Greek words, one can check the option "Greek only.
When one clicks on a Greek word, the word study window automatically loads the relevant word study.
