A method and system for providing readability control are described. The rendering and display of a data file on the display can be switched between a layout view and a column view. Initially, the data file is displayed on the display in one of the layout view or the column view. A portion of the displayed data file is selected by positioning a cursor over the portion and a trackball is actuated, for example, by clicking and holding the trackball for a predetermined time to display the data file in the other of the layout view or the column view within the selected portion. The selected portion is rendered on the display and centered generally in the vicinity of the cursor position when actuating the trackball.
