Highlight text in Pages on iPhone
You can temporarily highlight text in the body of your document, in text boxes and in shapes. This is helpful, for example, if you’re reviewing a document and want to call out certain parts. These highlights aren’t visible in printed documents. When multiple people are working on a document, each person’s highlights appear in a unique colour.
Tip: If you want highlights in any colour that are visible in your final document, add a background colour to text.
To learn how to change your highlight colour, see Set your author name for comments.
