发明名称 Annotations for Electronic Content
摘要 Embodiments are described for capturing, displaying, and navigating text annotations in a non-modifiable document. In some embodiments, a determination is made that a text annotation is to be created and a system determines the file position of the selected object. The file position of the selected object can be stored along with the created text annotation in another file or a non-read only portion of a file storing the document. Using the file position, the text annotation may be identified with the selected object without modifying the non-modifiable document. In some embodiments, once a text annotation is displayed a user may easily navigate among the captured annotations.
