A primary graphical input device such as a scroll bar or slider is displayed in order to allow graphical input and adjustment of at least one parameter, such as the page number of a displayed document in a word-processing program or a range value in a data visualization routine. Whenever a user activates the graphical input device, the user may set and change the parameter not only purely graphically, as in conventional applications, for example by dragging some portion of the primary device by moving a mouse, but also by entering a specific value into the secondary graphical input device, for example, via a keyboard. The invention thus provides an intuitive way for a user to quickly and easily navigate graphical objects not only by using pointing devices, but also by entering alphabetic or numeric input, all while maintaining the inherent advantages of 'point and click' graphical displays.
