Putting a line through a word (take it you mean crossing-out so you can still see the original word?) - in "reply", you get the options top left: B=bold, I=italic, u=underline, S= strikethrough. So highlight the word you want to modify then click the relevant modification. Strikethrough is the one you want in this case.
