Abstract: An electronic device displays a view of a lower portion of a first column from a document. The document includes at least a first column and a second column. A first user input gesture is received by the electronic device. In response to detecting the first user input gesture, the electronic device displays an animated transition from the view of the lower portion of the first column to a view of an upper portion of the second column.

Abstract: Methods and devices are provided. A method includes at an electronic device with one or more processors, a display, and memory, displaying, by the display, a playback position indicator for a media file; receiving, by the electronic device, a user input for adjusting a position of the playback position indicator from a first position of the media file to a second position of the media file; and in response to receiving the user input, displaying, by the display, a snippet from a document corresponding to content of the media file at the second position of the media file.

Abstract: A method for detecting content on a page of digital media that has a reading direction by reading image data beginning from a starting point in the reading direction of the digital media and identifying the content by analyzing differences in the image data as the image data is read. The method can include mapping a boundary of the content based on variations between content image data and surrounding background image data and generating a content map for the page using the boundary of the content, where the content map allows the page to be navigated between multiple pieces of content.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a document authoring application which when executed by at least one processing unit provides a graphical user interface (“GUI”) for the document authoring application. The GUI includes a display area for displaying a document being authored. The GUI also includes a document authoring tool for adding to the document a floatable content control. The floatable content control includes (1) a content display area for displaying content specified for the floatable content control and (2) a selectable user interface item (UI) that when selected causes the document authoring application to display the content display area. The floatable content control for display by a document viewing application such that the document viewing application displays the specified content through the content display area when the document viewing application receives a selection of the UI item.

Abstract: Some embodiments provide a content processing application with a novel annotation migration operation that allows the application to automatically migrate annotations from a first version of content such as a document to a second version of the content. Examples of such annotations include user-specified notes, highlights, bookmarks, and/or other annotations. The content processing application examines different sets of content segments in the second version to identify a particular set of content segments that matches a first set of content segments in the first version associated with a particular annotation. Upon identifying a matching particular set of content segments, the content processing application associates the particular annotation with the particular set of content segments in the second version. The content processing application can then provide a presentation of the second version with the particular annotation for the matching particular set of content segments.

Abstract: A content presentations editing application for editing a structured electronic document that includes mathematical objects is provided. The content presentation editing application selects a portion of the document, the selected portion including at least one mathematical object. The content presentation editing application centers the selected portion of the document by identifying an alignment symbol in the mathematical object and aligning the mathematical object to a particular position in the document at the identified alignment symbol. To align the mathematical object, some embodiments move the mathematical object such that the alignment symbol is at the center of the page. For mathematical objects that are located within cells of a table, the center alignment operation moves each mathematical object in the table such that the identified alignment symbol aligns with the center of the table column that contains the mathematical object.
