Highlight text in Numbers on Mac
You can highlight text in text boxes and in shapes. These highlights aren’t visible in printed spreadsheets.
When multiple people are working on a spreadsheet, each person’s highlights appear in a unique color. To learn how to change your color, see Set author name and comment color in Numbers on Mac.
Tip: If you want highlights that are visible in your final spreadsheet, add a background color to text in any color. This type of highlight isn’t included with Numbers review tools.
