Add and print comments in Keynote on iPad
You can add comments to text, objects, graphs, table cells and slides. A small square appears next to text (which is also highlighted) to indicate a comment is attached. Comments attached to shapes are also indicated by a small square. Comments in table cells are indicated by a triangle in the corner of the cell. When you don’t want comments to be visible, you can hide them, and you can print a presentation with or without comments.
When multiple people are working on a presentation, each person’s comments appear in a unique colour and include their author name. Anyone can reply to a comment, which is especially useful if you’re collaborating — you can add a comment and with back-and-forth replies, have a conversation in real time.
Note: Comments aren’t visible in printed presentations unless you select that printing option.
Add, edit or delete a comment
You can add and edit your own comments, and anyone can delete a comment.
Select text, or tap an object or a table cell, then tap Comment.
Note: If you tap the background of the slide (so that nothing is selected), you can add a comment to the slide that always stays open. You can resize the comment and reposition it on the slide. Others can’t reply to this type of comment.
Type your comment, then tap Done.
To view, edit or delete your comment, do one of the following:
Open a comment: Tap the comment marker.
Edit a comment: If you’re the comment’s author, tap the comment marker, tap in the text, type your changes, then tap Done.
If there are replies to your comment, you can’t edit the original comment by tapping its text. Instead, tap
at the top of the comment, tap Edit Comment, make your changes, then tap Done.Delete a comment: Tap the comment marker, then tap Delete at the bottom of the comment. If there are replies to the comment, this action deletes the entire conversation. You can delete an individual reply only if you’re the author of the reply or the presentation owner.
If the comment is on the slide background, move the pointer over the comment, then tap Delete.

Review a comment or conversation: Scroll through the text. If a comment is truncated, tap Show More. If replies are hidden, tap “View [n] more replies”.

If the comment is on the slide background, move the pointer over the comment, then tap the arrows.
