The Scroll Bar Wars of Changes to the Scroll Bar

The Andrew scroll bar had two functions: It was used to move through a document, and it functioned as a visual indicator to show which part of the document was currently displayed and the approximate length of the document. The first version of the scroll bar was a white box with a black line indicating the part of the document currently in view. The location of the text caret in the document was indicated by a black circle within the scroll bar; this circle would enlarge when a part of the text was selected.
