<p>A method and apparatus for providing zoom functionality in a mobile device display are described. In the method, a data file is displayed on the portable device display in a full layout view. A cursor is displayed in the layout view as a zoom icon, such as a magnifying glass cursor, with which any portion of the layout view can be selected by positioning the icon and triggering a zoom tool in response to actuation of an input device, such as trackball, on a mobile communications device. In response to actuation of the trackball, the selected portion is displayed in the portable device display at a next higher magnification. The process can be repeated to successively zoom in on a desired portion of the data file, until a maximum magnification is reached.</p> |
