I am trying to highlight text in FM, but cannot find a way to do that. Any ideas?
In the edit window, or in the rendered output text?
And if the latter, what version of FM. Newer releases support background fill for text.
You can designate a highlight behind an entire paragraph style in Paragraph Designer > Font, but more likely you want to highlight specific strings. In that case, create a character style in Character Designer and set the background color to your highlight color. Be sure to set Window to As Is so that you can use it on any paragraph style.
