What you are seeing probably isn't highlighting but text (or
paragraph) shading. To remove it, select the text and, on the Format
menu, click Borders and Shading. Click the Shading tab. Click the "No
Fill" option and then click OK. Alternatively, press Ctrl+SpaceBar to
remove all font formatting not in style. (If the formatting comes from
a paragraph style, you would have to modify it to get rid of the
shading.)
