Highlight text in Pages on Mac
You can highlight text in the body of your document, in text boxes and in shapes. 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. To learn how to change your colour, see Set author name and comment colour in Pages on Mac.
Tip: If you want highlights that are visible in your final document, add a background colour to text in any colour. This type of highlight isn’t part of the Pages review tools.
Highlight text
Select the text you want to highlight.
Do one of the following:
Press Shift-Command-H on the keyboard.
Select Insert > Highlight from the Insert menu at the top of your screen. (The Insert button on the Pages toolbar doesn’t have the Highlight command.)
Click Highlight in the review toolbar at the top of the document. The review toolbar is visible only if there are already comments, highlights or tracked changes in the document.
You can’t highlight text in table cells, but you can add conditional highlighting to a cell to change the cell’s appearance based on its value.
Add a comment to highlighted text
Click the highlighted text.
In the pop over, click “Add a comment”, then type your comment.
Click Done.
You can also add a comment to highlighted text in the Comments and Changes sidebar on the left. To open it, click 
in the toolbar, then select Show Comments Pane (or Show Comments and Changes pane).
Remove a highlight
If a document is shared with others, only you and the document owner can remove your highlight.
Move the pointer over the highlighted text, then click Delete in the pop over.
If no pop over appears, that means the highlight was added as colour behind the text. To remove it, remove the background colour.
Note: If the document is shared with others, only you and the document owner can delete your highlight. If someone else adds a comment to your highlight, the author name and colour of the highlight changes to the comment’s author, and you can’t delete the comment.
Remove all highlights and comments from text
You can quickly remove highlights and comments from body text in your document.
Select the text where you want to remove highlights and comments.
To remove them for all body text in the document, press Command-A on your keyboard.
Select Edit > Remove Highlights and Comments (from the Edit menu at the top of your screen).
Highlights and Comments on text in text boxes, shapes and tables are not affected.
