There are two ways to highlight text:
Add a permanent highlight: Add color behind text to create a highlight effect. With this method, the highlight appears in printed documents.
Add a highlight for content review purposes: Use the text review toolbar to temporarily highlight text and add comments. With this method, highlights don’t appear in printed documents.
Select the text.
Click the Style button near the top of the sidebar on the right.
If you don’t see a sidebar, or it doesn’t have a Style button, click
in the toolbar. If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Style button.
In the Font section, click
, then choose a color from either the Character Fill Color well or the color wheel.
The left color well shows colors that match the template. The color wheel on the right opens the Colors window, where you can choose any color.

To remove the color, select the text, then click the Character Fill Color well and choose the swatch that has a diagonal line through it at the bottom-right corner of the well.
Select the text, then do one of the following:

Choose Insert > Highlight (from the Insert menu at the top of your screen).
Note: The Insert button on the Pages toolbar doesn’t have the Highlight command.
Click Highlight in the gray review toolbar at the top of the document.
The review toolbar is visible only if there are already tracked changes, comments, or highlights in the document.
To remove the highlight, click the highlighted text, then click Delete in the comment that appears.
