What did the + and - buttons do for the Xerox Star scrollbar? And is there any particular reason for its arrows to be inverted?

- justsomehnguy 3y ago> Between 1981 and 1982, the Xerox Star moved the scrollbar to the right to get it out of the way and reduce visual clutter. Scroll arrows pointed inwards in the direction the content would move based on user studies, and + and – buttons allowed for scrolling by pages. The thumb was a fixed size diamond, independent of how much of document is visible. Clicking in the thumb elevator region would jump to that part of document.[7]
- tail_exchange 3y agoThat's interesting. Maybe just a product of what I expect from the UIs nowadays, but the arrows seem very counter-intuitive, and the + and - buttons lead me to believe it is going to zoom in and out from the document, not scroll by pages.
