Yes, the red color means I think it is a correction. If you see red on the last letter of a word and the first letter of the next word, it means I deleted some text that was between these words. Usually you see the blue color after a / mark, so that means I think it is an alternative, another way of saying it that may or may not be better. If there is no / mark then blue means the word or text is optional, that is you can use it there or not use it. That is how I should have shown "then". The green color means I moved the word or some text within the sentence.Originally Posted by vox05
