Recently used annotations are listed in the Recent Comments section of the My Comments Toolchest. Annotations that are added to a document or modified on a document will automatically be added to this list. This list keeps the 30 most recently used annotations.
To permanently keep an item from the Recent Comments list, right-click (Mac: Ctrl+click) the annotation in the Recent Comments list and select Save Comment from the context menu.
To add a Recent annotation to a document, click the annotation in Recent Comments, and then click the location on the document to place the annotation. Once placed the annotation can be edited as normal.
Recent comments can be reordered, deleted, or resized.
