Grouping markups
You can group two or more markups together so that your comments function as a single
comment. You might group your markups temporarily to move them to a new location or
to modify their properties rather than editing each one individually. Grouping also helps to
distinguish your markups from other reviewers' markups in a document review.
Note: You cannot group text edit markups.
To group markups:
1. Using the Hand tool, select a markup.
2. Ctrl-click (Windows) or Command-click (Mac OS) to select all the markups you want to
group.
3. Right-click (Windows) or Control-click (Mac OS) anywhere in the selection, and choose
Group from the pop-up menu.
To ungroup markups:
Right-click (Windows) or Control-click (Mac OS) the grouped selection, and choose
Ungroup from the pop-up menu.
