When you click on Correct an entry you will see a box to correct in . Above the box you will see (in English if you read it in English) B - I - U (abc) T (eraser) <<<<<< B = bold I = Italics U = Underline abc = cross out like T = FONT COLOR +++ CHOOSE ONE Erase = delete. If you have a Korean interface I don't know what it shows, but to choose to color in red, highlight the letters or words and go to the T and choose a color from the box. Try it. Nancy
