Manipulating visual representations of data

A computer program product, encoded on a non- transitory computer-readable storage device, operable to cause data processing apparatus to perform operations comprising:

• causing display, in a first operating mode, an initial view of a first portion of a document in an application window;
• determining whether there is an input to an input device within a threshold time;
• in response to the threshold time being elapsed without receiving the input to the input device, entering a second operating mode, wherein the entering the second operating mode comprises causing display of a visual guide and a zoomed-out view of the document, wherein the visual guide comprising comprises a frame that indicates a size and location of the first portion of the document relative to the zoomed-out view;
• causing a second portion of the document that is not being displayed in the zoomed-out view to be displayed in the visual guide in response to an auto scroll operation triggered by the visual guide being placed within a predetermined distance to an edge of the zoomed-out view.

A system comprising:

• a processor and a memory operable to perform operations comprising:
• in a first operating mode, presenting, in a user interface, an initial view of a first portion of a document;
• in response to an input not being received within a predetermined time period, entering a second operating mode to update the user interface with a zoomed-out view of the document;
• rendering a visual guide on the user interface to encompass the first portion of the document in the zoomed-out view;
• moving, in the user interface, the visual guide to a second portion of the document in response to a change in position of a cursor in the user interface;
• and in response to a request to zoom in the second portion of the document causing display of a zoomed-in view of the second portion of the document identified by the visual guide in the zoomed-out view, wherein the request to zoom in the second portion of the document comprises modifying a size of the visual guide, wherein the zoomed-in view displays the second portion identified by the modified visual guide.
