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.
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.
Select the text you want to highlight.
Choose Insert > Highlight (from the Insert menu at the top of your screen).
The Insert button on the Numbers toolbar doesn’t have the Highlight command.
You can’t highlight text in table cells, but you can add conditional highlighting to a cell to change a cell’s appearance based on its value.
Click the highlighted text.
In the popover, click “Add a comment,” then type your comment.
Click Done.
If a spreadsheet is shared with others on iCloud, only you and the spreadsheet owner can remove your highlight.
Move the pointer over the highlighted text, then click Delete in the popover.
Note: If the spreadsheet is shared with others, only you and the spreadsheet owner can delete your highlight. If someone else adds a comment to your highlight, the author name and color of the highlight changes to the comment author, and you can’t delete the comment.
