ABSTRACT:
Provided is an apparatus and method for a secondary scroll bar that yields increased granularity in scrolling through a viewable object, such as a document displayed within a window of a graphical user interface of a computer system. Initially, an icon is displayed within the graphical user interface which, when activated by a user, provides this secondary scroll bar. Next, the secondary scroll bar is displayed within the window in response to a selection of the icon by a user, wherein the secondary scroll bar allows a user to scroll through a narrowly defined region of the viewable object, in response to activation of the icon. Delimiter marks are also displayed within a primary scroll bar upon which the secondary scroll bar is dependent, in response to the selection by the user of the secondary scroll bar. The delimiter marks indicate a searchable range of the viewable object by the secondary scroll bar. Thereafter, the user can scroll through the narrowly defined region of the viewable object by utilizing the secondary scroll bar. Additionally, multiple additional scroll bars can be activated by the user to provide increased granularity on multiple levels when scrolling through the viewable object.
