  • Track changes permissions
    Patent number: 9122886
    Abstract: Various features and processes related to document collaboration are disclosed. In some implementations, animations are presented when updating a local document display to reflect changes made to the document at a remote device. In some implementations, a user can selectively highlight changes made by collaborators in a document. In some implementations, a user can select an identifier associated with another user to display a portion of a document that includes the other user's cursor location. In some implementations, text in document chat sessions can be automatically converted into hyperlinks which, when selected, cause a document editor to perform an operation.
