Two-dimensional document navigation

A non-transitory computer-readable storage device including program instructions executable by one or more processors that, when executed, cause the one or more processors to perform operations, the operations comprising:

• receiving a first user input signal requesting a document preview view of a plurality of documents from a document list that includes at least a first document and a second document, wherein the first document is designated as an active document;
• in response to the first user input signal, outputting for display the document preview view including an active document representation of content from the first document, wherein a first portion of the active document representation is visible in the document preview view;
• receiving, while the preview view is displayed, a second user input signal;
• determining whether the second user input signal corresponds to a document navigation request or a document change request;
• in response to determining that the second user input signal corresponds to the document navigation request, repositioning the active document representation such that a second portion of the active document representation is visible in the document preview view;
• and
• in response to determining that the second user input signal corresponds to the document change request, designating the second document as the active document.

An apparatus, comprising:

• one or more processors;
• and
• one or more memory devices for storing program instructions used by the one or more processors, wherein the program instructions, when executed by the one or more processors, cause the one or more processors to:
• receive a first user input signal requesting a document preview view of a plurality of documents from a document list that includes at least a first document and a second document, wherein the first document is designated as an active document;
• in response to the first user input signal, output for display the document preview view including an active document representation of content from the first document, wherein a first portion of the active document representation is visible in the document preview view;
• receive, while the preview view is displayed, a second user input signal;
• determine whether the second user input signal corresponds to a document navigation request or a document change request;
• in response to a determination that that the second user input signal corresponds to the document navigation request, reposition the active document representation such that a second portion of the active document representation is visible in the document preview view;
• and
• in response to a determination that that the second user input signal corresponds to the document change request, designate the second document as the active document.
