The 
Annotation panel provides access to all of the document’s annotations to assist you in making them accessible.
Basic Annotation Actions
Basic Annotation actions offers automated batch processing of one or more annotations. You can run these actions on the selected annotations or on the whole document.
In each case you can specify which annotations should be processed. In the action dialog you can define the Annotations to which the actions will be applied.
Annotations panel
Annotation view
In the Annotations panel you can manually Edit, Tag and Delete selected annotations.
Click on the 
Options menu (or right click) at the panel toolbar to see all available actions that works for the current annotation selection.
Tag Annotation
Creates a new appropriate tag for the selected annotations. If disabled, it means the annotation is already tagged. You can use 
Find Tag to navigate to this tag.
Delete Annotation
Clicking 
Delete will remove all selected annotations. Instead of outright deletion, consider 
Flatten annotations to preserve important information.
Find Tag for Annotation
The Find Tag feature navigates to the associated annotation tag.
Annotation Properties
Click 
Properties to see available annotation properties to edit. Change Contents key, annotation flags, name or Modified key.
Annotation Attributes
Annotation Attributes provide low-level access to the Annotation object.
We do not recommend using this for editing an annotation unless you have deep PDF format expertise.
Annotation Actions
Each annotation can have an associated list of actions. You can add, remove, and edit actions in the Actions tab in the Properties view.
