Numbers

Highlight text in Numbers on iPad
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 colour. To learn how to change your colour, see Set your author name for comments in Numbers on iPad.
Tip: If you want highlights that are visible in your final spreadsheet, add a background colour to text in any colour. This type of highlight isn’t included with Numbers review tools.
