Claim:
A method of displaying large format data files with predetermined dimensions and resolution on a display of a portable electronic device comprising: entering a first display mode to render a viewable portion of a large format data file on the display using the large format data file's predetermined dimensions and resolution; and displaying non-viewable portions of the large format data file in response to a cursor on the display moving near an edge of the viewable portion of the large format data file by automatically scrolling the viewable portion in the direction of the approached edge to reveal an updated viewable portion of the large format data file; receiving a selection signal to change to a second display mode; and switching between the first display mode and the second display mode in response to the selection signal, wherein the second display mode includes rendering one or more fields from the large format data file as a list of fields for field-to-field navigation without maintaining the predetermined dimensions and resolution of the large format data file.
