1. A method for accessing a data field comprising:
- providing a scalable scroll controller including a scale controller to modify a scale for controlling a magnification for accessing data within the data field;
receiving a user event to modify scale through the scale controller;
automatically adjusting the scalable scroll controller to maintain a center of the scalable scroll controller unchanged in response to receiving the user event; and
adjusting the scale based on the receiving of the user event to modify scale through the scale controller.

Abstract
A method for accessing a data field having fine resolution is disclosed. The method includes providing a scalable scroll controller with a scale controller to modify a scale for controlling a magnification for accessing data within the data field. The method also includes receiving a first user event to select the scale controller and receiving a second user event to modify a position of the scale controller. The scale is adjusted based on the position of the scale controller. An apparatus for performing the method is also disclosed.
