Navigation > Settings > Change marking settings

Change Marking uses the last_updated field which is present for most EA element to highlight text & diagrams which have changed since a specified date.

You can choose both the date, and the color to use for the highlighting.

Note: Due to restrictions in MS Word, only a restricted set of colors is available to highlight Diagrams which have changed.

For the moment, this has been fixed as being yellow, so we suggest that, unless you feel very strongly, you use yellow as the change marking color.
