Thank you for the explanation, keshab! Learning something new every day.
SDL also has its own review tool.
Select a segment and go to Edit> Comments. Instead of indicating a word like MS word, it takes the whole segment and you have to indicate the errors in it. After completion the review of the segment, go to Edit>Marker>Set Marker. the reviewed segment becomes marked in red.
It's cool. Isn't it?
However, I'm afraid that is not cool. It's just another example of how counter-intuitive and antiproductive SDLX really is!
